Show 1905.] OF PHYTOPHAGOUS COLEOPTERA. 415 anterior portion of tlie elytra are normal or accidental, I am unable to say. The design of the elytra resembles that of Hoino-phceta 8-guttata Fab., but in that insect the vertex of the head has the characteristic white or flavous patch and the clypeus is of similar coloration ; the elytra are smooth, and the intermediate flavous patch is never subdivided ; in the Peru species the metatarsus is moderately elongate and the claw-joint rather strongly swollen. A sph .e r a n it id is s im a , sp. n. (Plate XIV. fig. 5.) Broadly ovate, black; clypeus fulvous; thorax strongly transverse, fulvous, anterior angles toothed; elytra strongly convex, minutely punctured, bright metallic green, the lateral and apical margins and a narrow transverse band at the middle flavous or fulyous. Length 10 millim. Head impunctate, blackish; frontal elevations transverse, bounded by a deep groove behind ; clypeus fulvous, acutely cari-nate at the middle; diameter of each eye of less width than the dividing space; antenna? long and slender, extending below the middle of the elytra, black, the third joint shorter than the fourth; thorax more than twice as broad as long, the lateral margins strongly rounded, deeply and broadly sulcate, the anterior angles strongly produced into a blunt tooth, the disc impunctate, fulvous, sometimes marked with two small fulvous spots ; scutellum black; elytra broad, convex and widened posteriorly, deeply sulcate within the shoulders and with another shallow depression below the base, very minutely punctured, very bright metallic green, this colour divided at the middle by a narrow transverse fulvous band which joins the similarly coloured lateral margins; under side and legs black; the metatarsus of the posterior legs as long as the following two joints together; claw-joint strongly swollen. Hab. Pacliitea, Peru. Larger and more broadly ovate than the other similarly coloured species of the genus; the antenna? slender and proportionately long; the thorax strongly toothed; the metatarsus somewhat intermediate between that of Oedionychis and the present genus as a rule, but as long as the following two joints together. A sphjera v ir id ic o l l is , sp. n. Black; thorax bright green, impunctate, the sides gradually flattened; elytra black or seneous, deeply foveolate, the lateral and apical margins green. Length 7 millim. Of medially slightly widened shape ; the ^head black, impunctate, frontal elevations broad and convex ; clypeus triangularly widened, not ridge-shaped ; antennse black, the third and fourth joints equal; thorax not more than twice as broad as long, rather widened at the sides, the lateral margins feebly rounded, anterior margin concave, its angles moderately produced, not toothed, the |
