Trigonops platessa Hllr. 1 9 genitalia and 2 spermatheca sty-stylus; c-co.\ite; vf-valvtfer; 9ths- nineth stemite; 8tlis-eight sternite; spg-spermatliecal gland; nd-nodulus; mi-ramus; cu-comu. found in other species of this genus. The internal sac of the male genital tube was successfully extruded as shown in Fig. 33. These structures serve as a pattern of the genitalia found in other species of Trigonops. T. platessa is rather uniform in size, the fe- males a little larger than the males, rostral space between the scrobes narrow; rostral base tumid, sulcus straight, eyes prominent, not conicaUy pointed, prothorax wider than long; elytra widest near the humerus, transversely concave, inter- vals 4-5 elevated at declivity and with conical elevation on the dorsolateral margin of the meso- thorax. This species is similar in many respects to T. coerulescens. Trigonops granulosa n. sp. Fig. 35 Body derm black, legs, antennae and tip of rostrum reddish-brown, clothed with sparse small round brown and some gray scales. Rostrum as long as head, separated from head by a lunulate suture; base of rostnmi tumid and punctuate, corina short terminating at de- clivity in a small elevation, declivity sparsely punctate and free of scales; rostrum narrow, scrobes small, separated by width of distal end of scape. Antennae slender, scape reaching an- terior two-fifths of prothorax; funicle segments 1 as long as 2, 3 almost as long as 2; 4-7 mainly obpyrifonn, club as long as 5-7 combined; small punctures and colorless scales on scape, none on funicle, setae short, bowed and brownish in color. Head very rugous, frons concave near junction with rostral suture, fonning a shallow depression, small brown scales on elevated thickened lines;. Fig. 35. Trigonops granulosa n.
