rngiilose appearance especially toward apex. Abdomen somewhat alutaceons, 

 very finely, sparsely pnnctiared. Legs slender and rather long. Length 

 10.4-14.0 mm. ; width 5.0-6.5 mm. 



California (San Francisco). 



This species also appears to be confined to the coast regions about 

 San Francisco, where it is very abundant. In its normal state, the 

 setae growing from the elytral punctures are always long and dis- 

 tinct, and the original type of affinis does not differ in the slightest 

 character from the species described by Mannerheim as inhabiting 

 the immediate locality alluded to. The setae are, however, liable to 

 be broken off or rubbed out of the punctures, which will account for 

 several errors in the books. 



C. iienioralis Esch. — Zool. Atl. Ill, p. 8. — Oblong-oval, moderately 

 convex, shining, the pronotum generally alutaceons ; elytra often subconical. 

 Head rather small, very coarsely, deeply, somewhat densely punctate ; antennse 

 rather slender, the eleventh joint but slightly narrower than the tenth. Pro- 

 thorax rather short, from three-fifths to three-fourths wider than long, the apex 

 about two-thirds as wide as the base, the latter nearly as in esckscholtzi, but 

 with the basal angles generally a little more abru^jtly and distinctly prominent 

 posteriorly ; sides broadly rounded anteriorly, straighter and more nearly 

 parallel toward base ; disk finely but deeply, distinctly and not very sparsely 

 punctate toward the middle, the punctures becoming gradually quite coarse 

 and dense toward the sides ; lateral edges with a moderately thick convex 

 bead, often abnormally sinuate near the basal angles. Eli/tra a little more 

 than twice as long as the prothorax, coarsely and not very densely punctate, 

 strongly rugulose from the coalescence of the punctures toward apex, but very 

 feebly so toward base, the punctures generally very unevenly distributed. 

 Abdomen polished, very finely, sjiarsely punctate, the pubescence rather long 

 and very fine. Length 6.8-9.8 mm. ; width 3.5-4.5 mm. 



California (San Francisco). 



A very small species, confined to the same regions as viatica and 

 esckscholtzi and also very abundant. Its resemblance to the latter 

 of these species is so marked, that mistakes are very liable to occur 

 in identifying the extremes of each ; with large series, however, it 

 is readily seen to differ by certain constant characters, among which 

 may be mentioned the smaller, more coarsely punctured head, very 

 slightly shorter prothorax, and distinctly more finely and sparsely 

 punctured elytra, the setae of both the elytra and abdomen being a 

 little longer, more evident and more persistent; it is also constantly 

 much smaller in size and slightly less convex. It varies remarkably 

 in size.
