Oblongus, elytris gibbosis, Icete rufus; antennis, corpore infra, pedibus elytrorumque maculis duabus subquadratis nigris, elytris distincte punctato-striatis. Long. 12 millim. Hab. Peru, Chancamayo (Buckley). Like B. glyptoderus, "but differently shaped; the thorax is wider and has the sides much more rounded ; the elytra are much more convex, their surface (as well as that of the thorax) is smoother, but with the series of punctures more distinctly impressed ; the scutellum is black in one example, reddish in another ; the underside is black, excepting the head, which is wholly red, the sides of the thorax, the two apical segments, and a spot in the middle of two segments preceding them. The coxse and the trochanters are pitchy red. The thorax in one example has a spot on the front margin, four small ones transversely placed, and three linear basal marks, but all nearly obliterated. This insect is no doubt subject to variation, but, from its form and the smooth surface, is distinct from B. glyptoderus. 11. BRACHYSPHENUS PERVERSUS, sp. nov. Ater, glabratus; elytris singulis seriebus quinque punctorum postice abbreviutis, externe punctis nonnullis confuse dispersis flavis, sutura, limbo laterali tenuiter plagiaque magna in singulis suturce adjuncta nigris, abdomine castaneo-rufo. Long. 12 millim. LLab. Colombia, Medellin. This species resembles no other that I am acquainted with except Acronotus annularis. If the yellow ring of that species were obliterated just behind the scutellum the pattern of the elytra would be nearly similar. The head and thorax are, however, entirely jet-black. The structure of the prosternum is, moreover, that of Sterno-lobus. The sterna, legs, epipleurse, and limb of the elytra are black ; the abdomen chestnut-red, without spots or clouds. The form of the insect is almost exactly that of Acronotus; the elytra, however, are rather more convex than in A. annularis. 12. AULACOCHILUS MOLUCCANUS, sp. nov. Late ovatus, nigro-sub ceerulescens, glaber, nitidissimus, pedibus abdomineque castaneis, elytris convexis. Long. 7 millim. Hab. New Guinea. Var. immaturus 1 piceus, corpore infra dilutiore. LLab. Mysol (coll. Armitage). Head smooth, excepting the epistome, which is rather thickly punctured ; antennas pitchy black, the apex of the club and the basal joint paler, the third joint distinctly elongate, the fourth to the seventh bead-shaped, the eighth transverse ; palpi pitchy red. The thorax is, at the base, more than twice as wide as long, the base |
