BEJIBIDIIN/E 41 



legs piceorufous; head three-fourths as wide as the prothorax, with 

 rather deep sulci and strongly convex front between the latter; an- 

 tennae piceous-black, the basal joint slightly paler, slender, nearly 

 four-fifths as long as the elytra, the medial joints not quite three 

 times as long as wide; prothorax nearly one-half Avider than long, 

 the sides strongly reflexed, rounded, generally somewhat more prom- 

 inently so near the middle, oblique and broadly, very feebly sinu- 

 ate basally, the angles obtuse but rather sharp; surface nearly as 

 in the preceding, except that the foveae are rather less strongly 

 rugose; elytra one-half longer than wide to a little less, only two- 

 fifths wider than the prothorax, parallel, circularly rounded in apical 

 third, the sides subparallel and feebly arcuate; striae fine, moderately 

 impressed and with feebly convex intervals throughout, the deep 

 apical part of the fifth longer and less oblique than in oppressum, 

 the foveae at three-sevenths and three-fourths. Length (d 71 9 ) 3-2- 

 3.5 mm.; width 1.2-1.35 mm. California (Sonoma and Sta. Clara 

 Cos.). Eight examples flebile n. sp. 



Form more narrowly oblong, still smaller in size, similar in coloration 

 of the body, legs and antennae; head nearly four-fifths as wide as 

 the prothorax; antennae slender, almost three-fourths as long as the 

 elytra, the medial joints between two and three times as long as 

 wide; prothorax two-fifths wider than long, the broadly, rather 

 strongly arcuate sides slightly oblique and broadly and not strongly, 

 though distinctly, sinuate behind, the angles obtuse but sharp; sur- 

 face nearly as in the preceding; elytra also nearly as in flebile, but 

 narrower, though one-half wider than the prothorax, the latter being 

 relatively somewhat narrower than in flebile. Length (c/ 1 9 ) 2.9- 

 3.2 mm.; width 1.1-1.2 mm. California (Gualala and Anderson 

 Valley, Alendocino Co.). Three specimens timefactum n. sp. 



Form and coloration nearly as in the two preceding, but with more nearly 

 deep black legs and antennae and more transverse prothorax; head 

 three-fourths as wide as the prothorax, with deep and rather narrow 

 sulci; antennae subequal in length to the elytra, not very slender; 

 the medial joints between two and three times as long as wide, the 

 basal joint piceous; prothorax short, fully one-half wider than long, 

 the sides strongly, evenly rounded, oblique and distinctly sinuate 

 behind, the angles right and sharp; surface nearly as in the pre- 

 ceding, except that the transverse impressions are more distinct, 

 the foveae very large but barely concave, rugose, with a long linear 

 impressed medio-basal part, the carina moderate; elytra oblong, 

 with parallel and broadly arcuate sides, two-fifths longer than wide, 

 circularly rounded in about apical third, one-half wider than the 

 prothorax, the striae well impressed and with moderately convex 

 intervals throughout, the fifth as in the preceding two species; foveae 

 near two-fifths and four-fifths. Length (cf 9 ) 2.75-3.3 mm.; width 

 1.15-1.4 mm. Colorado. Levette collection. Fifteen specimens.
