MARTIN JACOBY ON NEW SPECIES [Mar. 4, regular rows, their epipleurae veiy broad, continued to the apex ; below flavous, the tibiae and tarsi black (sometimes only inf uscate), the posterior tibiae wdth a small spur, the others unarmed; pro-sternum narrow, anterior cavities open. Hab. Espirito Santo, Brazil. What I take to be the female of this species differs in having a rather broad reflexed lateral margin to the elytra, and the upper surface of a more pronounced fulvous; otherwise there is no difference of any importance. The species differs from C. flava Clark and C. testacea CI. in the general smaller size, the arrangement of the elytral punctuation, and in the black tibiae and tarsi. In the female the elytral interstices are more or less costiform. The species, like several others placed in this genus, has entire, not emarginate tibiae. CACOSCELIS VARIPES, sp. n. Below black ; head and thorax fulvous, impunctate ; elytra dark greenish, opaque, minutely punctured; the anterior and intermediate femora fulvous, the tibiae and tarsi and the posterior femora black. Length 10 millim. Head extremely minutely punctured when seen under a strong lens, fulvous, the frontal elevations subquadrate, rather strongly raised; clypeus with a highly raised blunt ridge between the antennae, the last-named organs black, the basal joint fulvous, the terminal two joints very elongate, much longer than the preceding ones ; thorax nearly twice as broad as long, slightly narrowed anteriorly, the sides feebly rounded, with a rather broad flattened margin, the base with a shallow sulcus, not extending to the sides, the anterior angles slightly thickened, the surface impunctate, fulvous; scutellum broad, black; elytra slightly wider at the base than the thorax, rather convex, of opaque greenish colour, very finely punctured, with a narrow reflexed lateral margin, their epipleurae very broad and concave; below clothed with grey pubescence, black, the anterior and intermediate femora fulvous; tibiae not emarginate at the apex, the first joint of the posterior tarsi as long as the following joints together. Hab. Brazil. Of this species, which differs in coloration from any of its allies, a single specimen is in m y collection, without any exact locality. It is somewhat allied in colour to C. opacipennis Jac, from Colombia, but differs entirely in the shape of the thorax and the colour of the underside and legs. CACOSCELIS CERULEIPENNIS, sp. n. Pale fulvous, the antennae (thefirst joint excepted) black; head and thorax impunctate; elytra dark violaceous blue, finely and closely punctured, with traces of longitudinal sulci. Length 7 millim. Head fulvous, entirely impunctate, the frontal elevations |
