[Received May 13, 1905.J (Plates XIY. & XV.*) In the 4 Proceedings ' for 1894 (p. 609) I have given the descriptions of many species belonging to the group of bladder-clawed Halticince, which until then were simply Catalogue names as published by Clark. The number of further species which I have received since enables me to publish here a considerable addition to my former paper; where Clark's names have been retained for the same species I have stated this, but by far the greater portion of my species were not known to Clark. The genera Oedionychis and Asphcera as at present understood almost rival in species the Galerucid genus Diabrotica, and it is frequently very doubtful to which of the two genera a species should be referred. Yon Harold has tried to point out the differences between Oedionychis, Asphcera, and the allied genera (Coleopterol. Hefte, xv. p. 91), and lays the principal stress on the more or less elongate first joint of the posterior tarsi in Asphcera in contradistinction to the corresponding very short joint in Oedionychis, which in most cases holds good, but in many instances there are intermediate degrees as Avell as in the more or less inflated claws, so that it is uncertain to which genus these species should be referred; these are, however, rather exceptional, and v. Harold's definition must be accepted for want of a better one. All the species described here are contained in my collection. U omophceta c l a v a r e a u i , sp. n. Black, a frontal spot and the clypeus flavous; thorax fulvous, impunctate ; elytra nearly impunctate, fulvous, a broad transverse band at the base and another narrower one below the middle, black. Length 9 millim. Head black, very shining, with some punctures near the eyes the latter widely separated, with a flavous transverse spot at the intermediate space, frontal elevations narrow, likewise flavous as well as the clypeus; antenna? extending beyond the middle of the elytra, black, the first joint fulvous below, third and fourth joints equal; thorax twice as broad as long, the sides feebly rounded, with narrow thickened margins, the anterior angles strongly produced and thickened, the surface fulvous, impunctate, rather convex; scutellum black ; elytra with narrow, reflexed margins, microscopically finely punctured, fulvous, with a rather broad basal band occupying about one-fourth of the length of the elytra, its posterior edge oblique, widest at the suture, another narrower * For explanation of the Plates, see p. 460. |
