evidently less than half as long as the body; palpi very slender, the 

 last two joints equal in length; prothorax fully a fourth wider than 

 long, in outline nearly as in ruficollis and with similarly rounded 

 apical and basal angles, but with the sides rather less reflexed; 

 fovea vestigial, the median stria rather deep, biabbreviated; elytra 

 more elongate, fully three-fifths longer than wide, gradually ogival 

 with obtuse apex in about posterior half, less than a fourth wider 

 than the prothorax; striae moderately fine, abrupt, a little deeper 

 behind; intervals not quite perfectly flat; subscutellar puncture 

 distinct; dorsal punctures four; anterior male tarsi very moderately 

 dilated. Length (id^, 69) 7-5-8.2 mm.; width 3-2-3-6 mm.

piceolus n. sp. 

 ji_Form elongate-suboval, moderately convex, alutaceous, the elytra 

 opaque, with the reflexed margins not distinctly paler; legs dark 

 rufous; head elongate, four-sevenths as wide as the prothorax, the 

 eyes well developed but not very prominent; antennae very slender, 

 dark rufous; maxillary palpi with the last joint not quite as long 

 as the third; prothorax barely at all wider than long, the sides 

 broadly, subevenly arcuate, less so and subparallel basally; all the 

 angles rounded; surface subeven, the stria short; sides deeply 

 reflexed, broadly explanate posteriorly, the foveae and impressions 

 obsolete; elytra nearly two-thirds longer than wide, almost two- 

 fifths wider than the prothorax, somewhat evenly elongate-oval, 

 gradually pointed and ogival apically; striae very fine, only slightly 

 stronger apically, the intervals perfectly flat throughout, the sub- 

 scutellar puncture distinct; dorsal punctures fine, two to three in 

 number. Length (9) 9-5 mm.; width 3.5 mm. California (Los

12— Elytral stria? deep, sharply defined and groove-like, the intervals 

 throughout the length perfectly flat, micro-reticulate and minutely 

 and feebly, confusedly subpunctulate. Body elongate, narrow, 

 nearly parallel, polished and piceous-black, with diaphanously pale 

 thoracic sides; elytra alutaceous, with the narrowly reflexed edges 

 scarcely pale; head scarcely elongate, four-sevenths as wide as the 

 prothorax, with large but very moderately convex eyes; antennae 

 slender, flavate, nearly half as long as the body; last palpal joint 

 very gradually pointed, a little longer than the third; prothorax a 

 fourth wider than long, the sides broadly arcuate and converging 

 anteriorly, less arcuate and just visibly converging behind the 

 middle; basal angles narrowly rounded, the apical well defined and 

 prominent; transverse impressions nearly obsolete, the stria fine 

 but broadly impressed; fovea? short, linear and feeble, at basal 

 third; sides very narrowly and feebly reflexed, gradually a little 

 more widely so basally; elytra elongate, fully two-thirds longer than 

 wide, scarcely a fourth wider than the prothorax; sides parallel, 

 very feebly arcuate, rounding in about apical third; subscutellar 

 puncture strong; dorsal punctures two in number. Length (9)
