Described from a single pair (the female smaller) taken at Ungava 

 Bay, H. B.^T., by L. M. Turner. 



A quite distinct species, though evidently allied to unguicularis. The 

 latter is much larger, less elongate, and with different front claws in 

 the male. 



C. unguicularis Cr. 



Form oval, not or scarcely twice as long as wide, fulvotestaceous above, black 

 beneath. Male shining, female dull. Head at the extreme base, a small discal 

 spot and the middle of the base of the prothorax, and the suture and four 

 vittae on each elytron blackish or fuscous. The elytral vittae are rather wide, 

 the outermost one shortest, interrupted at middle and often more or less 

 confluent witth the next inner one. Head and thorax not very closely punc- 

 tulate, the punctures a little closer along the thoracic base ; elytra densely, rather 

 finely punctate, without series of coarser punctures. Beneath alutaceous in both 

 sexes, punctuation moderate in coarseness, typical in distribution. Front tarsi 

 of male broadly dilated, the second joint, not or only just perceptibly wider 

 than the first both claws stout, acuminate, the anterior one but little more than 

 half as long as the other. Length 5 to 5.5 mm. ; width 2.6 to 2.8 mm. 



Crotch's type was from British Columbia. Specimens at hand are 

 from Winnipeg, Le Pas, and Mile 214 H. B. Ry., Manitoba; Overland 

 Lake, Boulder Co., Colorado (Rohwer.) 



This is a very distinct and easily recognized species when due at- 

 tention is paid to its characters. It is our largest species with the 

 exception of impressopunctatus and or eg onus. Certain examples of 

 tumidiv entris approach the smaller specimens of unguicularis and look 

 quite similar but the resemblance is only superficial. 



C. oregonus sp. nov. 



Elongate oval, dull yellowish testaceous, shining (d 1 ), elytra each with four 

 rather wide fuscous stripes showing a tendency to confluence, the suture also 

 very narrowly dark. Head and thorax pale, almost throughout, a small discal 

 fuscous spot on the latter. Punctuation of elytra moderately close, rather fine, 

 without distinct series of coarser punctures; head and thorax more finely and 

 sparsely punctate as usual. Body beneath black, not alutaceous, moderately 

 coarsely punctate. Front tarsi of male broadly dilated, the second joint scarcely 

 visibly wider than the first, claws short, stout, evenly curved and mutually 

 equal. Length 5.8 mm.; width 2.85 mm. 



Corvallis, Oregon. A single male specimen submitted by Mr. 

 Sherman, who retains the type. 



Slightly larger and more elongate, but very similar to unguicularis 

 superficially. The size, vittate elytra, shining non-alutaceous lower 

 surface, and short, stout, equal claws of male front tarsi are sufficient 

 for its easy recognition. 



C. impressopunctatus Schall. 



Oblong oval, above yellowish testaceous, to dark ferruginous, head at sides 

 and behind, and base of thorax more or less infuscate; elytra either more or
