North America7i Species of Trogoj^hloeus. 337 



pressions which are distinctly sinuous and slightly convergent pos- 

 teriorly; surface finely, feebly and densely punctate, the punctures 

 abruptly scabrous and the surface dull very near the lateral edges. 

 Elytra quadrate, slightly wider toward apex, one-third wider and one- 

 half longer than the prothorax, impressed near the suture except to- 

 ward apex, densely, deeply punctate; punctures moderate, separated by 

 scarcely their own widths. Abdomen parallel, distinctly narrower than 

 the elytra, sides nearly straight; border moderate; surface minutely 

 and very densely punctate. Length 2.8 mm. 



California (Los Angeles 1). 



This species, although rather closely rallied to armahis, is 

 easily distinguished by its much shorter prothorax, in which the 

 sides are angulate, the angle not being appreciably rounded, by 

 its shape, the widest section being at a greater distance from the 

 apex, and by its rather shorter, and distinctly more slender an- 

 tennae. 



11 T. paciflcus n. sp. — Rather robust, moderately convex, pice- 

 ous-black; elytra slightly rufous; legs throughout and antennae pale 

 reddish-flavate, the latter slightly infuscate toward apex; pubescence 

 rather long and dense, somewhat coarse and erect; integuments mode- 

 rately shining. Head narrower than the prothorax, finely, feebly, and 

 densely punctate; antennal prominences moderate in length, rather 

 pronounced; antennae as long as the head and prothorax, rather slender;^ 

 club moderate; joints two to four decreasing uniformly and very 

 gradually in length, the second twice as long as wide, tenth scarcely a& 

 long as wide; eyes large, moderately prominent; tempora one-half as 

 long, strongly rounded throughout the length in circular arc. Pro^ 

 thorax widest at anterior two-fifths, where the sides are very strongly 

 rounded and subangulate, thence strongly convergent and nearly 

 straight to the base, slightly less strongly convergent to the apical 

 angles, which are acute and slightly dentiform; basal angles obtuse and 

 narrowly rounded; base almost transversely truncate, fully two-thirds 

 as wide as the disk and distinctly narrower than the apex; the latter 

 truncate; disk two-fifths wider than long, finely punctate; punctures 

 distinctly separated in the middle, large, variolate, scabrous, and poly- 

 gonally crowded in a broad area at the sides; impressions strong. Elytra 

 quadrate, slightly wider and one-half longer than the prothorax, im- 

 pressed along the suture, rather coarsely and deeply punctate, the 

 punctures separated by slightly more than their own widths. Abdomen 

 broad, but slightly narrower than the elytra, parallel; sides feebly 

 arcuate; border moderate, not very deep; surface feebly convex, mi- 

 nutely and feebly reticulate, very minutely and somewhat sparsely 

 punctate. Legs slender. Length 3.8 mm.
