the next two combined. Length (9 ) 4.8 mm.; width 1.9 mm. Cal- 

 ifornia (exact locality unknown but probably from the coast regions 

 south of San Francisco) osculans n. sp. 



Antennae distinctly thick, as usual in the first section 5 



5 Prothorax less than a third wider than long, distinctly wider at base 

 than apex. Body elongate-oval, convex, polished, black; head fully 

 three-fourths as wide as the prothorax and as wide as an elytron, 

 the parallel sulci deep and abrupt; prothorax nearly as in the pre- 

 ceding, except that the median stria does not attain the apex; elytra 

 oblong-oval, nearly as in osculans but narrower, with all the striae 

 outside of the second obsolete or nearly so, and the subapical punc- 

 ture extremely minute and feeble; anterior fovea behind basal fourth, 

 the second at two-thirds. Male with the basal joint of the anterior 

 tarsi very large, convex, barely longer than wide the usual type in 

 this section. Length (cf 9 ) 4.0-4.5 mm.; width 1.5-1.8 mm. Cal- 

 ifornia (Truckee). Oregon, LeConte. Five specimens. 



erasum Lee. 



Prothorax fully two-fifths wider than long, barely observably wider at 

 base than apex. Body much larger and broader, similarly polished 

 and deep black; head three-fourths as wide as the prothorax, the 

 sulci deep and abrupt, the superciliary fovea large and deep; an- 

 tennae notably thick, rather long, four-fifths as long as the elytra, 

 black as usual, but with the first joint rufous beneath, the second 

 joint three-fourths as long as the third, the tenth twice as long as 

 wide; prothorax in form and surface nearly as in osculans but 

 broader and more transverse; elytra nearly as in that species in 

 form and striation but broader, also less convex internally. Length 

 (9) 5-3 mm.; width 2.1 mm. California (Marin Co.). 



speculum n. sp. 



6 Antennae slender basally, becoming rather rapidly thick distally, the 

 tenth joint less than twice as long as wide and fully one-half thicker 

 than the second, the latter fully three-fourths as long as the third. 

 Body oblong-oval, rather convex, deep black, polished, with feeble 

 subcupreous lustre, the legs dark piceous, the antennae black through- 

 out and as long as the elytra; palpi black as usual; head three-fourths 

 as wide as the prothorax, the latter rather small, but little more than 

 a fourth wider than long, the foveae deep, lineate at the bottom, the 

 median stria distinct, entire; disk widest before the middle, the 

 sides broadly rounded, oblique and nearly straight in almost basal 

 half, distinctly reflexed; base slightly wider than the apex; elytra 

 oblong-oval, not quite one-half longer than wide, about one-half 

 wider than the prothorax, evenly rounded behind in fully apical 

 third; first two striae rather deeply, subequally impressed, the others 

 faint, rapidly becoming obsolete externally, the fovea? before basal 

 third and at three-fifths; subapical puncture very minute. Length 

 (9 ) 3-2 mm.; width 1.35 mm. California (Sta. Cruz Mts.).
