notal punctuation readily distinguishing it from any other. Per- 

 haps it is most closely allied to subpuhescens, but differs in its longer 

 prothorax and very much coarser and sparser elytral punctures. 



C. parviceps n. sp. — Elougate oval, moderately convex, ratlier dull and 

 alutaceous throughout ; elytra feebly undulato-rugulose, especially toward 

 apex. Head suiall, coarsely, deeply, moderately densely j^nnctate : antennae 

 moderate, third joint scarcely more than one-half longer than the second, 

 tenth triangular, as wide as long. Prothorax one-half wider than long, strongly 

 narrowed from base to apex, the latter scarcely more than one-half as wide as 

 the former ; apex very deeply sinuate ; base very broadly emarginate through- 

 out the width, the basal angles being acute and posteriorly prominent ; sides 

 evenly and rather strongly arcuate ; disk rather sparsely punctate, the punc- 

 tures distinct toward the middle, rather denser and decidedly coarse laterally ; 

 side margins extremely minutely, acutely beaded. Elytra but slightly more 

 than twice as long as the prothorax, extremely finely, not very densely punc- 

 tate, the punctures much finer than those near the sides of the pronotum 

 and becoming, toward apex, excessively minute and feeble. Abdomen rather 

 strongly convex, very finely, sparsely punctate, each puncture bearing a long 

 hair. Length 7.0-8.0 mm. ; width 3.4-4.0 mm. 



California (San Diego). 



The punctures of the pronotum and elytra bear each a long rather 

 coarse fulvous seta, the vestiture being closely recumbent and very 

 conspicuous. This is a small and comparatively isolated species. 



C. sefOSUS n. sp. — Oval, strongly convex, rather shining, the pronotum 

 slightly alutaceous ; elytra extremely feebly undulato-rugulose toward apex. 

 Head well developed, finely and sparsely punctured ; antennae long and some- 

 what robust, third joint twice as long as the second, tenth nearly as wide as 

 long, strongly obtrapezoidal. Prothorax two-thirds wider than long, the apex 

 two-thirds as wide as the base, the latter broadly, very feebly arcuate, broadly 

 distinctly sinuate laterally, the basal angles right, not rounded and projecting 

 posteriorly slightly beyond the median portions ; sides almost evenly and 

 rather feebly arcuate ; disk sparsely and extremely finely punctate toward 

 the middle, the punctures becoming much denser, rather strong and distinct , 

 laterally, the setse very short and inconspicuous ; side margins finely and 

 acutely beaded. Elytra fully two and one-half times as long as the prothorax, 

 evenly and unusually obtusely rounded behind, densely and rather strongly 

 punctate, the punctures much larger than any of those of the pronotum, and, 

 toward apex, becoming rather fine and more feeble, each with a moderately 

 long, robust, erect and fulvous seta, the vestiture dense but not conspicuous. 

 Abdomen finely, sparsely punctate. Length 10.0 mm. ; width 5.0 mm.

 This species is readily distinguishable by its oval, strongly convex 

 form, and peculiarities of the elytral pubescence. It is probably
