Show 1886.] REV. H. S. GORHAM ON NEW COLEOPTERA. 159 Mas. Tibiis anticis dente acuta, adjacente, infra medium; intermediis apice mcurvato, posticis leviter sinuatis. Hab. Madagascar (Cowan). Entirely black, subopaque above, body beneath shining. Antennae rather short, a little longer in the male than in the female, their club not very wide nor abrupt; head rather uneven, with a few scattered obsolete punctures. Thorax half as wide again as long, opaque ; punctuation very obsolete, minute and scarcely visible, basal sulci distinct; front angles very little produced, scarcely at all in the female, sides nearly straight, base finely margined. Elytra halt as wide again as the thorax and slightly widened behind, callus only faintly raised. The male specimen has two minute red dots near the apex of the elytra, in the female they are wanting. Meta-sternum (in male) depressed between the hind coxae, and first ventral segment with scattered small punctures. Two specimens from Dr. Sharp's collection. ANIDRYTUS, Gerst. 1. ANIDRYTUS QUADRIPUNCTATUS. Oblongus, parum ovatus, rufo-piceus, nitidus, crebre subobsolete punctatus, cupreo-pubescens; antennis nigris, articulis quatuor basalibus et apice summo rufis,- prothorace punctis quatuor discoidalibus nigris. Long. 8 millim. $ . Hab. Brazil, Blumenau. Head finely punctured, a little rugulose between the eyes ; basal and three following joints of the antennae pale ferruginous, the fourth joint being deeper in colour, and at its articulation with the third nearly black. Thorax just twice as long as wide, from the front angles the sides are very evenly rounded to near the base, where they become straight. The basal furrows are two distinctly impressed, converging, linear channels ; within them, where they end on the front of the disk, halfway between the base and the front margins, are two round black points (as in A. bipunctatus) ; more in front and more widely apart are two other black points. The disk and sides of the thorax are evenly, thickly, not confluently punctured, but the surface of the black spots is smooth, or in the external spots with one or two punctures only. The elytra are somewhat parallel, not strongly convex, evenly and more thickly punctured; the punctures are (as is usual where they give rise to hairs) not pricked in, but irregular, somewhat linear, and flat-bottomed. Legs clear red, only a very little darkened at the base of the tibiae. The underside wholly ferruginous red. Although this appears to be a species very nearly allied to A. bipunctatus, Gerst. (a species also from Brazil), the description given above will show that it differs not only by the four black spots of the thorax, but by the colour of the underside and legs as well. I have only seen one specimen, a female, which was sent to m e by Herr Reitter, with other Coleoptera collected in the same district. |
