North American Species of Trogophlmis. 335 



Easily distinguishable from armatus by its more robust an- 

 tennae, paler legs, denser punctuation, and the tempora not acute 

 and prominent at base; from dentiger it may be known by its 

 black color and more shining surface. 



8 T. armatu^i n. sp. — Moderately robust and convex, piceous; 

 prothorax slightly paler; antennae fuscous, scarcely perceptibly paler 

 toward base; legs pale, piceous-brown; pubescence fine, moderate in 

 length, dense; integuments feebly shining. Head five-sixths as wide 

 as the prothorax; antennal prominences strong; surface minutely, 

 feebly, and extremely densely punctate, alutaceous; antennae as long as 

 the head and prothorax, moderately robust, gradually, moderately 

 clavate, all the joints longer than wide, two to four gradually and not 

 very rapidly decreasing in length, second three times as long as wide, 

 tenth just visibly longer than wide; eyes large, moderately prominent; 

 tempora nearly one-half as long, acutely angulate behind. Prothorax 

 widest at anterior third, where the sides are very narrowly rounded, 

 thence strongly convergent and nearly straight to the base, feebly con- 

 vergent and feebly arcuate to the advanced, acute, and prominent 

 apical angles; basal angles obtuse, rounded; base feebly arcuate, 

 scarcely two-thirds as wide as the disk, and scarcely more than three- 

 fourths as wide as the apex; the latter broadly, feebly eraargiuate, the 

 middle being nearly straight, and with the edge very thin and trans- 

 lucent; disk one-third wider than long, very finely, feebly, and densely 

 punctate; punctures all well separated; impressions strong. Elytra 

 distinctly wider and nearly one-half longer than the prothorax, quad- 

 rate, each impressed along the suture, rather finely, strongly, and 

 densely punctate; punctures separated by fully their own diameters. 

 Abdomen slightly narrower than the elytra ; sides parallel and nearly 

 straight; border moderate, rather deep; surface feebly convex, very 

 finely and densely punctate. Legs slender. Length 2.3-3.9 mm. 



California (Mt. Diablo, San Jose, Gilroy Hot Springs 3). 



The prothorax is rather longer, narrower, and paler in color 

 than in the other species of this vicinity, resembling more nearly 

 the shape of the same part in dentiger and texanus. 



9 T. gilae n. sp. — Moderately slender, very feebly convex, piceous- 

 black; legs brown; antennae fuscous; pubescence short, very fine, dense, 

 but rather dark in color, and not at all conspicuous; integuments, 

 especially the elytra and abdomen, distinctly shining. Head much 

 narrower than the prothorax, broadly convex, minutely, densely punc- 

 tate ; prominences moderate, slightly longer than wide : eyes large, 

 convex, rather prominent; tempora short, parallel, much less promi- 

 aient, angulate behind, one-third as long as the eye; antennae slender.
