California (Napa and Humboldt Cos.). 



A well-marked species allied to viatica, but readily identified by 

 its larger size, much longer prothorax and coarser punctuation. I 

 took a large series on the low ground bordering the tule lands near 

 Benicia ; when living it is very strongly pruinose. 



C. Tiatica Esch. — Zool. Atl. Ill, p. 7. — Elongate, parallel, strongly con- 

 vex, shining, the pronotum rather strongly alutaceous ; surface nearly smooth. 

 Head generally somewhat finely and sparsely punctured ; antennas rather 

 robust. Prothorax from one-half to three-fifths wider than long, the apex 

 about two-thirds as wide as the base, the latter subtruncate, broadly, very 

 feebly sinuate laterally, the basal angles subacute and generally projecting 

 posteriorly very slightly beyond the median portions ; sides generally strongly 

 convergent from base to apex, distinctly and evenly arcuate, sometimes slightly 

 more strongly arcuate before the middle ; disk extremely finely punctate 

 throughout, the punctures but moderately dense toward the sides, the lateral 

 edges very minutely beaded. Elytra always much more than twice as long as 

 the prothorax, very sparsely and minutely punctured throughout. Abdomen 

 very sparsely and extremely minutely punctured. Legs slender. Length 

 10.0-13.0 mm. ; width 4.2-5.8 mm. 



California (San Francisco). 



In the large series of seventeen specimens before me, there is 

 none which can be positively asserted to have been taken in any 

 other locality than that indicated; it appears to be a species peculiar 

 to the sandy coast region, perhaps extending down to Monterey 

 or Santa Barbara. Viatica is very readily known by its slender 

 parallel form and very minute punctuation ; from elongata it may 

 be separated at once by its much shorter prothorax and very much 

 more pronounced longitudinal convexity. 



C. escllSCholtzi Mann. — Rev. Zool., 1840, p. 138; affinis Lee: Ann. 

 Lye, V, p. 130. — Oblong-oval, rather strongly convex, moderately shining, 

 the pronotum strongly alutaceous; elytra frequently slightly conical. Head 

 anteriorly somewhat coarsely and densely punctate ; antenna? rather robust. 

 Prothorax from one-half to two-thirds wider than long, the apex somewhat 

 feebly sinuate and rather less than two-thirds as wide as the base, the latter 

 transverse or very feebly arcuate, moderately sinuate laterally, the basal 

 angles acute and slightly prominent posteriorly ; sides generally rather 

 strongly arcuate anteriorly, more nearly straight toward base ; disk very 

 finely and rather sparsely punctate except toward the sides, where the punc- 

 tures become rather coarse and denser; lateral edges with a thick convex 

 bead bordered internally by a fine deep groove. Elytra always distinctly 

 more than twice as long as the prothorax, rather densely, very coarsely and 

 deeply punctate, the punctures unevenly subcoalescent, producing a strongly
