Show 258 MR. M. JACOBY ON THE [Feb. 2, The sculpturing of this species is quite exceptional amongst the African representatives of the genus, but it approaches in that respect, as well as in colouring, C. smaragdulus, Fabr.; but the present species has entirely black antennas, rounded shoulders, and the arrangement of the punctures in rows can only be seen in certain lights, as they are so closely approached and having the interstices nearly as strongly punctured. CRYPTOCEPHALUS TRISULCATUS, Suffr. Black, clypeus white; thorax and elytra fulvous, the former with two oblique black bands; elytra moderately strongly punctured, a spot on the shoulder and two others, obliquely-transverse, near the apex black; femora black and white. Var. Thorax with four black spots, elytra without any spots. Length 2 lines. Head black, very finely punctured at the vertex ; the clypeus and the sides below the eyes yellowish white; antennas slender, black, the lower five joints testaceous, the third joint one-half longer than the second, the fourth shorter than the fifth joint, terminal joints elongate in the male, shorter in the other sex; thorax strongly narrowed in front, the sides evenly rounded, posterior margin bisinuate at the sides, the surface nearly impunctate, fulvous, the posterior angles flavous, all the margins narrowly black, the middle of the disc with two oblique longitudinal bands, not extending to the apex, and scarcely to the base; scutellum black; elytra rather finely punctate-striate near the suture, the punctures nearly obsolete at the base, tbe sides more strongly and closely punctured, with the interstices slightly convex, the lateral margins posteriorly as well as the apical ones narrowly black, a black spot is placed on the shoulder and two others near the apex, of these one is situated across the suture, the other rather larger one near the lateral margin and a little higher than the sutural spot; underside and the femora black, the anterior femora with their lower surface nearly white; tibias fulvous, or stained with piceous at the apex; prosternum wdth two small teeth at its base, yellowish white, as well as the mesosternum and the space between the posterior coxas, the entire underside nearly impunctate. Hab. Natal, Estcourt (67. Marshall). The position of the elytral spots differs from that of any other African species except C. erythromelas with which I a m acquainted, and the white clypeus, prosternum, and bicolored anterior femora are likewise characteristic of the present insect. The variety differs in no way from the type except in the absence of the elytral spots and in the breaking up into four spots of the thoracic bauds; the former are placed quadrately, thus indicating the oblique shape of the bands in the normal form, marking their commencement and end. I have given here a new description of Stiffrian's species, with which the present insect agrees so closely that I must identify it with it, although the specimens before m e are smaller than the size given by Suffrian; this author had also probably old specimens |
