374 Coleopterological Notices. 



In the material before me there are some other doubtful forms 

 represented in each case by one or two specimens. Some of these 

 will quite probably prove to be valid species, but I have preferred 

 not to name them at present. 



C, audomilialis Lee. — Proc. Ac. Phila., 1859, p. 77. — Robust, strongly 

 convex, parallel, but slightly more than twice as long as wide, shining, llxnl 

 rather small and coarsely punctate ; antenna? black, rather robust. Prathorax 

 nearly two-thirds wider than long, generally widest at about the middle, the 

 sides thence parallel and nearly straight to the base, broadly rounded ante- 

 riorly ; base transverse, the angles very feebly produced posteriorly; disk 

 very finely and sparsely punctate, a little more coarsely and densely so later- 

 ally, the lateral edges narrowly but strongly reflexed. Elytra from one-third 

 to two-fifths longer than wide, rather coarsely deeply and sparsely punctate, 

 and distinctly rugulose, especially toward the apex. Abdomen coarsely but not 

 very densely punctate, more or less rugulose. Length 14.0-17.0 mm. ; width 

 7.0-8.3 mm. 



California (Monterey; Santa Barbara; Los Angeles). 



The edges of the elytra, when viewed laterally, are generally very 

 feebly arcuate, sometimes nearly straight. The punctuation of the 

 upper surface is rather constant, but the sculpture of the abdomen 

 varies considerably, a specimen from Santa Barbara before me 

 having the surface smooth, polished, almost devoid of rugulosity. 

 and finely and very sparsely punctate. The elytra are a little more 

 than twice as long as the prothorax in the female, relatively shorter 

 in the male. 



C. oralis Lee. — Ann. Lye. N. Y., V, p. 131.— Oblong-oval, strongly con- 

 vex and shining; sides nearly straight in the middle. Head very nearly one- 

 half as wide as the base of the prothorax, rather coarsely and densely punctate ; 

 antennae blackish, pale at apex, moderate. Prothorax rather short, from three- 

 fourths wider than, to nearly twice as wide as long; sides feebly arcuate, 

 generally convergent from base to apex, very feebly so and sometimes nearly 

 parallel in basal half; base truncate, very feebly sinuate near the angles 

 which are slightly produced posteriorly; disk sparsely but rather strongly 

 punctate toward the middle, densely and very coarsely so laterally, the sides 

 not narrowly reflexed but strongly finely beaded. Elytra always distinctly 

 more than twice as long as the prothorax, sometimes feebly inflated behind 

 the middle, unevenly, very coarsely and deeply punctate, the punctures often 

 irregularly coalescent, especially toward apex. Abdomen finely, rather sparsely 

 punctate, the punctures subtransverse, very feebly asperate, especially toward 

 the sides. Length 10.0-11.5 mm. ; width 5.2-5.7 mm. 



Oregon: State of Washington; Vancouver Island; Montana 

 (Bitter Boot valley).
