1 86 MEMOIRS ON THE COLEOPTERA 



subdeplanate edge turning inward slightly and disappearing near 

 basal third, the foveae unusually short, very broad and shallow, 

 separated from the sides by a surface which is nearly flat to feebly 

 convex; stria very fine and subentire; elytra one-half longer than 

 wide, slightly wider than the prothorax, parallel, very obtuse at apex 

 and convex, the oblique sinus long, extremely feeble and nearly 

 obsolete, the discal puncture strong, at three-fifths; basal joint of 

 the hind tarsi longer than the next two combined and much longer 

 than the fifth. Length (cf 9 ) 12.0-12.7 mm.; width 4.7-5.0 mm. 

 Oregon (Clackamas Co.) and California (Yreka) . . semipunctatus Lee. 



Alternate intervals only punctulace apically 13 



13 Elytra fully one-half longer than wide 14 



Elytra much shorter, less than one-half longer than wide 15 



14 Body larger and stout, nearly as in semipunctatus, strongly convex; 

 elytra (c/ 1 ) more opaque than in the preceding, very opaque (9); 

 head nearly similar but rather less rugose, the rugae distinct, however, 

 near the somewhat smaller foveae; prothorax nearly similar but 

 relatively not so large, the foveae similarly very feeble and diffuse 

 but not so short; elytra more elongate, about a fifth wider than the 

 prothorax, parallel, with feebly arcuate sides and rapidly very 

 obtuse apex, the sinus feeble though much more evident than in 

 semipunctatus, the striae still finer, the scutellar similarly long, the 

 intervals more absolutely flat in both sexes; minute and sparse 

 punctulation barely traceable at the sides, the apical punctured 

 parts of the alternate intervals very short, the punctures very fine, 

 almost obsolete in the female; hind tarsi nearly similar. Length 

 (cf 9) ii. 0-12. 8 mm.; width 4.3-5.1 mm. California (Sonoma to 



Monterey). Rather abundant solidus n. sp. 



Body much narrower and not so convex; head minutely, sparsely punc- 

 tulate basally and with a few stronger punctures and rugulae near 

 the small but deep foveae, the eyes very moderate, the antennae 

 slender, of the usual coloration, the palpi black, with pale tip; 

 prothorax still more parallel, with more feebly arcuate sides an- 

 teiiorly, otherwise as in solidus, except that the reflexed edge is 

 narrower and more deeply concave, the gutter expanding slightly 

 posteriorly and traceable almost to the base; general punctuation 

 finer, the rugulosity less evident and the surface more shining, the 

 large vague foveae nearly similar and separated from the sides by a 

 rather narrower and more convex surface; scattered punctures of 

 the lateral slopes not so large, the lateio-basal parts densely and 

 subconfluently punctured as in all others of this section; elytra fully 

 a fifth wider than the prothorax, parallel, with feebly arcuate sides 

 and rather abruptly obtuse apex, the binus long and feeble but 

 evident, the tips near the suture similarly obtuse; striae, intervals and 

 punctuation as in solidus, the lustre ( 9 ) rather less densely opaque; 

 hind tarsi with the first joint much longer than the next two or the 

 fifth. Length (9) 1 1. 8 mm.; width 4.5 mm. California (Sta. 



Clara Co.) incertus n. sp. 



15 Form more abbreviated than in any of the preceding and much 

 smaller in size, oblong-suboval, only moderately convex; head with
