Show 596 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA. [Nov. 16, Length 4|-5 lines. Head with some fine punctures and irregular impressions near the eyes ; anterior margin of labrum testaceous ; antennse black, extending one third the length of the body, apical joints long. Thorax about twice as broad as long, scarcely widened in the middle, sides nearly straight, the anterior angles produced and pointed ; surface with a iew distinct punctures near the base ; the disk remotely and finely punctate, with a deep round fovea at each side, and another oblique shallower depression at the lateral margin, as weil as the scutellum, black. Elytra oblong, convex, rather closely and deeply punctate, the punctures forming irregular double rows near the suture, but confusedly arranged at the rest of the surface. Underside and legs black. 33. PROSICELA BICRUCIATA, sp. nov. Oblong-ovate. Greenish black, shining ; elytra deeply punctate-striate, flavous ; the suture, a short transverse oblique band below the base, common to both elytra, and another larger one behind the middle greenish black. Length 5 lines. Head with a fine central groove and a few irregularly distributed punctures; labrum piceous, finely margined with testaceous ; antennae extending to half the length of the body, greenish black. Thorax twice as broad as long, its sides nearly straight, and the anterior angles produced into a point ; surface very minutely punctured, with a few remotely placed deeper punctures near the base greenish black ; scutellum impunctate. Elytra with about ten rows of rather deep punctures, visible to the naked eye, the punctures running in double lines towards the lateral margin ; the others consisting of single rows, but meeting at their ends at the apex, where the interstices are raised into costae ; they are of a light flavous colour, with a short transverse greenish-black band across the suture below the base having an upward direction, and another more irregular-shaped band, and hollowed at its anterior margin, extending nearly to the sides, below the middle ; the suture also is of the same colour, but gradually narrowed to the apex; claws simple. Genus D O R Y P H O R A , Illig. 34. D O R Y P H O R A PUNCTATISSIMA, Oliv. 35. DORYPHORA BATESI, Baly. 36. DORYPHORA PRINCEPS, Gray. 37- DORYPHORA FULGORA, Stall. The Ecuador specimens are devoid of the fulvous spots of the head and thorax, and approach nearer to D. celsa, Erichs. ; the coarser sculpturing of the elytra and the elongate terminal joint of the antenna?, however, distinguish it from that species. 38.
