California (Lake Tahoe — elevation 6300 feet). 



A good series of eight specimens shows that montana, although 

 allied to subpubescens, is abundantly distinct; it differs in its much 

 larger size, shorter, sparser and less conspicuous pubescence, and in 

 the nature of the elytral punctuation which distinguishes it at once 

 from that species. The punctures are generally distinct and deeply 

 impressed, but toward apex they gradually become smaller, and 

 finally extremely fine and feeble, and, — although in reality sepa- 

 rated by about the same interval between centres — apparently much 

 sparser. The majority of specimens display very distinct traces of 

 the three eroded grooves. 



C. pallidicornis n. sp. — Oblong-elongate, parallel, moderately convex, 

 smooth, strongly alutaceous throughout. Head somewhat coarsely but not 

 very densely punctate anteriorly ; antennse very slender, eighth joint much 

 longer than wide, tenth not quite as wide as long. Prothorax moderately 

 narrowed from base to apex, from one-half to three-fifths wider than long, the 

 sides moderately and almost evenly arcuate ; base transverse, feebly sinuate at 

 the sides, the basal angles being right, very narrowly rounded and but very 

 slightly prominent posteriorly ; disk very minutely, sparsely punctate toward 

 the middle, the punctures gradually coarser and quite distinct, but not very 

 dense, laterally ; marginal bead very fine. Elytra distinctly more than twice 

 as long as the prothorax, almost smooth but very dull, with feeble traces of 

 rugulosity, somewhat sparsely and very finely punctate, the punctures becom- 

 ing finer toward apex, each bearing a stiflT subrecumbent fulvous seta which is 

 rather short and inconspicuous, although projecting far beyond the limits of 

 the puncture. Abdomen sparsely, very minutely punctured. Length 8.2-9.0 

 mm. ; width 3.8-4.1 mm. 



Southern California. 



Allied to montana in the gradual decrease in size of the punctures 

 toward the apex of the elytra, but quite distinct in its smaller size, 

 smoother surface and very much shorter and less conspicuous pubes- 

 cence. It is much more elongate and Iqss convex than opaca, and 

 has the punctures toward the sides of the pronotum coarser and 

 very much sparser. The antennse and tarsi are testaceous through- 

 out, the legs piceous. 



C. genitiTa n. sp. — Oblong-elongate, parallel, with the sides straight, 

 rather strongly convex, the elytra rather shining, the pronotum strongly 

 alutaceous. Head well developed, coarsely deeply and rather densely punc- 

 tate anteriorly, much more finely and sparsely so posteriorly ; antennse rather 

 long and very slender, the third joint much more than twice as long as the 

 second, the tenth much longer than wide and but slightly wider than the
