148 MEMOIRS ON THE COLEOPTERA 



to about the middle; punctures strong and well separated basally, 

 finer posteriorly; foveae much before basal and near apical third. 

 Length (cf 9 ) 2.8-3.0 mm.; width 0.8-1. i mm. British Columbia 

 (Agassiz) gregale n. sp. 



Body much less elongate, polished, black, the anterior parts with steel- 

 blue to bronzy lustre; anterior elytral spots large, extending inward 

 beyond the middle, the posterior small, extremely feeble and often 

 wholly untraceable; legs rufo-piceous, the femora blackish; head 

 four-fifths as wide as the prothorax, the eyes large and prominent; 

 antennse as long as the elytra, fuscous and rather thick distally, grad- 

 ually less thick and testaceous basally, the medial joints about twice 

 as long as wide; prothorax in outline as in gregale but relatively 

 smaller, with smaller foveae and rather feebler line of confused punc- 

 tures along the bead; elytra barely one-half longer than wide, fully 

 one-half wider than the prothorax, oblong-suboval, the humeri rather 

 narrowly rounded; striae fine, not impressed, obsolete in apical third; 

 punctures distinct and rather widely separated; seventh series not 

 finer than the others, obsolete at the middle; foveae rather before basal 

 and behind apical third. Length (cf 9 ) 2.8-3.3 mm.; width i.o- 

 1.2 mm. Washington State (locality unrecorded; also at Spokane).

7 Form elongate-suboval, rather convex, highly polished, black, with- 

 out metallic lustre, the elytra generally wholly black, but sometimes 

 with a small and feebly defined post-humeral macula; legs piceo- 

 rufous, the femora blackish; head well developed, with prominent 

 eyes, generally but very little narrower than the prothorax; antennae 

 longer, almost as long as the elytra, blackish, in part rufous basally, 

 the medial joints more than twice as long as wide; prothorax mod- 

 erate, barely two-fifths wider than the long; sides subevenly, rather 

 strongly rounded from apex to a very short parallel part at the ob- 

 tuse but sharp and subprominent angles; base three-fifths the max- 

 imum width, the punctures before the bead strong, confused; foveae 

 moderate, formed as usual; elytra decidedly elongate, suboval, with 

 rapidly rounded humeri and gradually parabolic apex, distinctly 

 more than one-half longer than wide and about one-half wider then 

 the prothorax; striae subimpressed, obsolete somewhat behind apical 

 third as a rule, the punctures fine and rather close-set; foveae before 

 basal and near apical third. Length (c? 9 ) 2.9-3.25 mm.; width 

 1.0-1.15 mm. California (Sta. Cruz to Napa and Sonoma Cos.). 

 Rather abundant crurale Lee. 



Form less elongate; coloration and lustre as in crurale, except that the 

 legs are more often uniform obscure rufous, although the femora 

 are sometimes darker, differing especially in having the post-hu- 

 meral pale spot larger and only seldom barely traceable; head rela- 

 tively not quite so wide, with similarly large and prominent eyes, 

 fully four-fifths as wide as the prothorax, the antennae rather thicker 

 and not quite so long, similar in coloration, the medial joints about
