I, On the South American species of Diabrotica. Part I. By Josnry S. Baty, M.R.C.S., F.L.8., &e.

[Read July 3rd, 1889.]

In the present paper I have brought together all the South American species of the genus Diabrotica known to me, describing all those which appeared to be new, and re-characterising those which from the original brief and imperfect diagnoses required to be more fully defined. Since the publication of my papers on the Columbian Diabrotice I have received great numbers both of specimens and species from various parts of the South American continent; my knowledge of the limits of the various specific forms has thus been greatly extended, and I have been compelled to sink a certain number hitherto considered distinct into varieties of other earlier described species. In this paper the genus is divided into groups and sub-groups, which will, I trust, greatly facilitate the work of the student. I must beg to thank Messrs. Kirsch, Meyer, P. de Borre, Fry, Jacoby, Duvivier, Donckier de Donceel, Staudinger and TRANS. ENT. SOC, LOND. 1890.—PART I, (APRIL.) B

2 Mr. Joseph S. Baly on the

others, who have kindly placed their types and collections in my hands for examination and description.

This insect nearly equals D. regalis in size, but is narrower and more elongate. In my former paper I drew up my diagnosis on a specimen in which the two medial spots on the elytron were confluent, forming a transverse band. I have since received other specimens in which the band is divided into two distinct spots, as in D. regalis ; this is doubtless the normal coloration of the species.

D. gratiosa closely resembles elegantula; the thorax in the present species is convex, the deep fovea on either side being replaced by a small puncture, only visible when viewed sideways under a lens. It is also separated by the rounded, not plicate, sides of the elytra.

Thorax one-third broader than long; sides parallel and slightly sinuate from the base to beyond the middle, thence slightly rounded and obliquely converging towards the apex; upper surface convex, shining, impunctate. Elytra oblong-ovate, dilated posteriorly ; upper surface convex, finely punctured, jet-black, each elytron with three round spots or patches (two half-way between the basal margin and the middle, the inner one large, the outer one smaller and placed close to the lateral margin, the third subapical), and a transverse band just below the middle, abbreviated at either end, white or yellowish white. Legs almost entirely black.

The entirely black legs in both sexes and compressed joints of the antennez in the male, render this species easy to be recognised. Diabrotica fraterna, mihi, with which Mr. Jacoby has confounded this species, is much narrower and quite distinct.

Head not longer than broad, triangular; clypeus with a broad ill-defined longitudinal ridge; antenne about three-fourths the length of the body, filiform, the second and third joints short, the third slightly longer than the preceding one; the three lower joints piceo-fulvous, the ninth and tenth white. Thorax about one-half broader than long; sides parallel and slightly sinuate from the base to beyond the middle, thence obliquely converging towards the apex, all the angles very slightly produced, subacute ; disk convex, impunctate. Elytra oblong, slightly dilated pos- teriorly, convex, not depressed below the basilar space, distinctly and rather closely punctured.

Although the specimens that I have described as representing the typical coloration of this species, and those I have placed as varieties, at first sight appear very dissimilar, they do not differ more than the type and varieties of D. regalis, consentanea, and many others of the present group. All the forms of D. scripta agree in the black anal segment of the abdomen and in the coloration of the antenne, the ninth and tenth joints of these latter alone being white. The type may be known from its allies by the extreme base of the elytra being narrowly edged with fulvous, by the absence of a second subbasal spot (although specimens will possibly be found in which this spot is present), and in the position of the submedial one, which is placed much lower down on the disk than is usually the case in D. guttata and other similarly coloured species.

Hab. Colombia, Bogota, Magdalena River. My collection.

Head triangular, not longer than broad; longitudinal ridge on clypeus ill-defined; antenne filiform, three-fourths of the body in length, the second joint short, the third nearly one-half longer, the fourth longer than the preceding two united, two or three of the basal joints piceous beneath, the rest entirely black. Thorax nearly two-thirds broader than long; sides moderately rounded, nearly straight and parallel posteriorly; disk convex, obsoletely foveolate on either side. Elytra rather broadly ovate, slightly dilated pos- teriorly, convex, disk impressed with faint longitudinal suleations.

The present insect varies greatly in coloration; in the typical form the elytra are black, with the sutural and outer margins, together with several obliquely trans- verse lines on the disk, flavous; in some specimens the black colour gradually disappears until they may be described as flavous, with irregular black markings.

Head scarcely broader than long; longitudinal ridge on clypeus well-defined; labrum and eyes black; antenne filiform, equal to the body in length in the g, slightly shorter in the ?, the second and third joints very short, equal in length in the g, the third nearly one-half longer in the 9; pale piceous, the two lower joints, together with the tenth and eleventh, the extreme apex of the latter excepted, piceo-flavous (in some specimens these two are not paler than the preceding ones). ‘Thorax slightly broader than long; sides rounded anteriorly, distinctly sinuate and slightly converging behind the middle ; disk shining, impunctate, impressed on either side with a shallow fovea, which varies in depth in different individuals. Elytra oblong, slightly dilated posteriorly, convex, rather closely punctured, plicate below the humeral callus, the subhumeral ridge bounded within by a broad suleation, which varies in depth and in some cases is almost entirely obsolete; in the more strongly-marked specimens there are traces in addition of several shallow sulcations on the disk.

This insect closely resembles D. atromaculata in the pattern of its elytra, but is separated by the paler head, foveolate thorax and plicate sides of the elytra.

Thorax nearly one-half broader than long; sides slightly produced and rounded anteriorly, nearly straight and parallel behind the middle; disk convex, not foveo- late. Elytra oblong-ovate, convex, closely punctured ; flavous, each elytron with a narrow sutural line, dilated at the base and extending downwards slightly below the middle, a subtriangular basal patch covering the humeral callus, a subrotundate spot on the outer disk at its middle and two smaller spots placed transversely on the hinder disk, half-way between the middle and apex, black; the basal margin between the humeral patch and the suture also narrowly edged with black; the lower and inner angle of the basal patch is joined to the suture by a narrow piceous line.

The specimen of this species, kindly lent me by Mr. Jacoby, and from which the above description was drawn,. differs slightly in the coloration of its antenne and legs from tke diagnosis given in that author’s paper ; it is however, probably somewhat variable in colour.

Hab. Colombia (type); two specimens in my own collection. Central America (type and varieties). In most collections.

Head shining black; longitudinal ridge on clypeus well-defined ; antenne filiform, the third joint distinctly longer than the second, the fourth longer than the preceding two united. Thorax nearly one-fourth broader than long; sides diverging and sinuate from the base to the middle, slightly produced and rounded anteriorly, thence slightly converging towards the apex; upper surface smooth, impunctate, hinder disk flattened or slightly excavated, impressed with three shallow fovew, one on either side about the middle, the third less distinctly defined than the others and often obsolete, placed immediately in front of the basal margin. LElytra oblong, slightly dilated posteriorly, minutely punctured.

The present species is so closely similar in colour and variation of pattern to D. pulchella and adelpha, Harold, that without close attention to the sculpturing of the thorax it is quite impossible to separate them. In C. biannularis the hinder portion of the middle disk is more or less distinctly excavated, the excavated surface being impressed with three shallow fove, placed in a triangle, the hinder one sometimes obsolete ; this exca- vation varies greatly in depth, and in some few cases almost entirely disappears, in some specimens the hinder disk being simply flattened, but never, in any of the specimens that I have examined, convex ; in the two allied species the disk is regularly convex, its surface being bifoveolate in C. pulchella, whilst in C. adelpha the fovezx are obsolete.

This insect is so closely allied to D. biannularis, Harold, that it is quite unnecessary to give a detailed description ; the sole point of difference between the two being that in pulchella the thorax is convex and bifoveo- late, whilst in biannularis it is more or less distinctly excavated and trifoveolate.

This species, for the possession of which I am indebted to the kindness of Mr. Jacoby, differs in its smaller size and in the absence of any flavous coloration on the disk of the elytra. The specimen before me appears to be a ?; in the absence of the other sex I am compelled to keep the two species distinct.

Hab. Ecuador (Buckley). A single specimen in my cabinet.

Head not longer than broad, subrotundate; clypeal ridge strongly raised; antenne nearly three-fourths the length of the body, filiform, the second joint short, the third rather longer, the fourth longer than the preceding two united. Thorax nearly one- half broader than long; sides straight and parallel from the base to the middle, thence rounded and converging towards the apex ; disk convex, obsoletely deflexed on the sides. Elytra oblong, slighly dilated posteriorly, convex, rather strongly plicate below the humeral callus, disk rather closely impressed with fine punctures.

Diabrotica Gorhami agrees to some extent with D. nigromaculata, Jac.; it is, however, more oblong in form, more convex and the disk of the elytra is without the longitudinal sulcations present in the latter species ; the post-medial spot is probably at times more strongly developed.

Longitudinal ridge on clypeus ill-defined; antenne nearly four- fifths the length of the body, filiform, the second joint short, the third scarcely longer than the second, the fourth longer than the preceding two united ; the fifth, sixth, seventh, eighth and eleventh joints piceous, the rest obscure fulvous. Thorax shaped as in D. elata. Elytra rather closely and distinctly punctured, not depressed below the basilar space, obsoletely plicate below the humeral callus.

This species differs from D. elata in the coloration of the thorax, in the more distinct punctuation of the elytra and in the different coloration of the elytral markings.

Spec. 67. Diabrotica mutabilis, Baly. Journ. Lin. Soc., xix., p. 225. Hab. Colombia. My collection.

Very closely allied to D. twmidicornis, Erichs.; sepa- rated by its broader more oval form and by the presence of several faint longitudinal sulcations on each elytron (these are not mentioned in the original description) ; the antenne in the male are thickened as in the former species, but the two upper joints are less abruptly narrowed. In my original diagnosis of this insect I described the thorax as obsoletely bifoveolate: this is to some extent an error; the foveew vary in depth, but in the majority of specimens are well-defined.

This widely-spread species varies in the coloration of the antenne, tibie and tarsi, from flavous to nigro- piceous or black. Hrichson describes the breast and antenne as testaceous and the tibie and tarsi as flavous. His description of the markings on the elytra agrees with D. fusco-maculata, Jac., var. A, in the absence of the third fuscous spot. In inconstans, mihi, which I have united with the present species, each elytron has two large yellow patches, one basal, the other below the middle, the upper one being stained at its base with rufo- or nigro-piceous. D. viridula varies greatly in size.

The number and position of the dark markings on the elytra appear to vary greatly; in two specimens I have seen they form two narrow interrupted linear fascie.

Head not longer than broad, triangular; clypeus with a broad longitudinal ridge; antenne shorter than the body in both sexes, filiform, the second and third joints short, nearly equal, the fourth slightly longer than the preceding two united. Thorax slightly broader than long; sides nearly parallel and slightly sinuate from the base to beyond the middle, thence obliquely converging towards the apex, hinder angles subacute ; upper surface moderately con- vex, smooth, impressed more or less distinctly on either side with a round fovea, which is in some specimens ill-defined and in many instances entirely obsolete. Elytra ovate, dilated posteriorly, their apices rounded ; above convex, not plicate below the humeral callus, finely but rather closely punctured.

This common and variable species is found in nearly all the warmer parts of the South American continent and also in Mexico and other parts of Central America ; it varies greatly in the coloration of the head, under surface of the body and in the presence or absence of the yellow markings on the elytra; these markings, when present, appear to differ but little in form. The fovee on the thorax, as stated above, vary from being ' well-defined to entirely obselete, every stage being found between the two extremes. Having nearly one hundred specimens of the different forms, both in sculpture and coloration, now under my observation, I cannot but regard them as varieties of the same species, therefore am compelled to unite them under a single head.

Mr. Jacoby, in his diagnosis of D. Simoni, gives the thorax in the ? as being marked with four piceous spots. I have several specimens in my collection in which the thorax is more or less distinctly marked with piceous or fulvous, evidently the result of fading after death.

Elytra oblong-ovate, dilated posteriorly, convex, plicate below the humeral callus; surface closely and distinctly punctured.

After a careful examination. of a long series of this variable species I cannot separate D. lineolata, Kirsch (the type-specimen of which, through the kindness of the author, I have before me) as a distinct specific form. The head varies in colour from entirely black to entirely flavous; the antenne are also equally variable in tint. Dr. Kirsch lays stress on the absence of the discoidal foves of the thorax in his insect, but in the specimen before me they, although faint, are distinctly visible under a lens. Erichson only gives the thorax as bi- foveolate, the third fovea is always less distinctly defined than the others and in some specimens possibly entirely obsolete.

D. septemliturata is separated from D. Clarkella by its smaller size, and by the difference in the sculpturing of the thorax. It is also much more variable in the pattern of its elytra than that species.
