distinct toward the sides ; marginal cilia rather long, pale. Head 

 three-fifths as wide as the prothorax, strongly- and rather closely 

 punctato-rugose, the impressions snbobsolete ; epistoma rather 

 long, transverse, pale, the labrum one-half wider than long, broadly 

 arcuato-truncate ; eyes moderate in size and prominence, not at- 

 taining the base ; antenn.ne a little longer than the prothorax, 

 rather slender, joints five to seven subequal, eighth smaller, nine 

 to eleven wider, the tenth moderately transverse. Prothorax two- 

 thirds wider than long, the sides parallel, broadly and strongly 

 arcuate, more convergent and straighter anterioi'ly, the apex trun- 

 cate and equal to the base ; apical angles obtuse but scarcely at all 

 rounded from above, the basal A'ery obtuse ; disk strongly asper- 

 ato-punctate, more rugose toward the sides ; punctures not very 

 coarse. Elytra three-fifths longer than wide, very slightly wider 

 than the prothorax, parallel and straight at the sides, evenly 

 rounded at apex, rather finel}' but asperatel}' and somewhat closely 

 punctate. Abdomen somewhat thinly cinereo-pubescent. Length 

 2.5 mm.; width 1.0 mm. 



California (southern). The description is taken from the fe- 

 male, which is the only sex which I have seen, and in that sex the 

 fifth ventral is evenly and strongly rounded behind. The species 

 may be readily distinguished from the others which immediately 

 precede by its more asperate sculpture and smaller size. 



52. T. vilis n. sp. — Oblong, moderately convex, dull, the elytra shining, 

 black, the legs pale fen-uginous throughout; antenna? black, gradually pale 

 toward base, the first joint palest; pubescence rather long and coarse but only 

 moderately dense, not at all concealing the surface, cinereous, the semi-erect 

 pale hairs very sparse and only visible tOAvard the sides of the elytra; mar- 

 ginal cilia long and pale throughout, scarcely fimbriform. Head three-fourths 

 as vdAk as the prothorax, asperately though not densely punctate, the inter- 

 spaces strongly reticulato-rugose; impressions very feeble, epistoma moderate 

 in length, partly pale; labrum small, almost semi-circularly rounded; eyes 

 moderate, slightly prominent, not attaining the base; antennte well developed, 

 one-third longer than the prothorax, compact, the outer joints not at all asym- 

 metric and feel)ly transverse, fifth only just visil)ly larger. Prothorax three- 

 fifths wider than long, the sides parallel, evenlj^ and strongly arcuate through- 

 out ; angles all obtuse ; apex and base equal and somewhat arcuato-truncate ; 

 disk rather finely and sparsely but asperately punctate, the surface densely 

 reticulato-rugose, rather more strongly so toward the sides. Elytra not quite 

 one-half longer than wide, scarcely visibly wider than the prothorax, parallel, 

 very broadly and rather abruptly rounded behind, strongly but not very 

 densely punctate, the punctures small and feebly asperate but at the same
