antenna? blackish, the fnnicle slighth' pale toward base ; pubes- 

 cence blackish, long and coarse, very sparse, erect or semi-erect 

 and bristling, the marginal cilia of the elytra also black. Head 

 four-fifths as wide as the prothorax, smooth throughout, finely 

 and sparsel}^ punctate, the frontal impressions large and distinct, 

 approximate, the dividing convexity' rather prominent ; epistoma 

 somewhat narrow and long ; labrum a little wider than long, cir- 

 cularly rounded ; eyes rather large and prominent ; antenna? 

 siightl}' longer than the prothorax, incrassate toward tip, the pen- 

 ultimate joints distinctly transverse. Prothorax three-fifths 

 wider than long, the sides rounded at basal third thence feebly 

 convergent and just visibly arcuate to the broadly rounded apical 

 angles and more rapidly convergent and straight to the basal 

 angles, which are very obtuse but scarcely' at all rounded ; apex 

 and base equal, feebly arcuate ; disk minutel}' and remotel}' punc- 

 tate, not at all rugose at the sides. Elytra three-fifths longer than 

 wide, slighth' wider than the prothorax, parallel, rather strongly 

 but evenly rounded at apex, xQvy coarsely and sparsely but not 

 very deeph' and somewhat unevenl\' punctate. Abdomen very 

 finely and sparsely cinereo-pubescent. Length 2.3 mm.; width. 

 0.8 mm. 



Southern California. The single example before me is a male, 

 with the fifth ventral longer than the fourth and truncate at tip. 

 This species resembles lucidus in form but is smaller, with a dis- 

 tincth' larger head, still coarser and sparser and especially feebler 

 and less even elj'tral punctures, and ma}- be known also b}' the 

 absence of cinereous pubescence on the upper surface of the body. 



83. T. ril<«ticus □. sp. — Elongate, moderately convex, polished, black, 

 the legs piceons; antenn;ie rufo-piceoiis, blackish toward apex; pubescence 

 coarse, rather long, very sparse, subdecumbent and blackish, with numerous 

 long and erect, black and bristling seta.'. Head but little more tlian three- 

 fourths as wide as the prothorax, convex, smooth throughout, finely and 

 sparsely iiunctate, the frontal impressions rather small, apical and widely sep- 

 arated but distinct; epistoma rather long and somewhat narrow; slightly 

 pale: labrum in great part pale, slightly wider than long, strongly rounded; 

 eyes rather large but only moderately prominent and somewhat distant from 

 the base; antennte much longer than the prothorax, feebly incrassate, the pen- 

 ultimate joints distinctly transverse, fifth feebly dilated. Prothorax moderate 

 in size, three-fifths wider than long, the sides perfectly jiarallel and just visi- 

 bly arcuate, noticeably convergent and straight near the base, the angles very 

 obtuse but distinct, not rounded and feebly reflexed; apical angles but slightly 

 obtuse and extremely narrowly rounded ; apex and base broadly and almost
