Goleopterological Notices, VII. 651 



Prothorax small, shorter and only slightly wider than the head, scarcely % as 

 wide as the elytra ; antennae more elongate, the last three joints not broader 

 but less conical and very much elongated, at least in the male ; neck not ab- 

 ruptly constricted ungulare Lee. 



Of ungulare I have seen only the male, the characters assigned 

 to the first four species of the table are however taken throughout 

 from the female. 



C. versiCDlor. — Elongate, convex, alutaceous in lustre, minutely, closely 

 punctured and uniformly clothed with fine, short, pale and decumbent pubes- 

 cence throughout; body varying from blackish throughout, with the legs, front 

 parts of the head and basal and apical parts of the antennae paler, to pale tes^ 

 taceous throughout, the apex of the femora, especially the posterior, generally 

 suffusedly darker and the tip of the tibiae blackish ; pronotum in intermediate 

 forms blackish, with the flanks, tip and median basal parts paler, or pale tes- 

 taceous throughout, with two discal blackish spots; elytral suture and basal 

 parts of the flanks frequently blackish. Head elongate, slightly more than % 

 as wide as the base of the prothorax, the post-ocular portion feebly impressed 

 along the middle, conical with the sides feebly sinuate; neck abruptly but mod- 

 erately constricted; eyes large, separated by }4 of their own width. Antennse 

 about as long as the head and prothorax, the three outer joints very feebly 

 swollen, paler and more finely pubescent, the ninth and tenth subequal, }4 

 longer than wide and distinctly shorter than the eighth; eleventh elongate- 

 oval, about as long as the two preceding combined. Prothorax slightly elon- 

 gate, strongly campanulate, the apex rounded and about % as wide as the base, 

 the latter transverse with the sublateral sinuations feeble; sides rounded, 

 strongly convergent from near the middle; basal angles acute and strongly 

 everted; disk evenly convex, the median line sometimes feebly impressed an- 

 teriorly. Scutellum well developed, campanulate, not quite as long as its 

 basal width. Elytra 3 times as long as wide, fg wider than the prothorax and 

 more than 3 times as long; sides subparallel, gradually rounded and convergent 

 in apical fourth or more; apex of each evenly and rather narrowly rounded; 

 disk longitudinally and feebly impressed within the rounded humeri, each 

 with feeble traces of three fine, longitudinal, elevated lines. Legs long and 

 very slender; hind tarsi as long as the tibiae. Length 10.0-12.5 mm.; width 

 2.2-3.2 mm. 



Colorado? 



Four specimens are before me from the Levette cabinet, with- 

 out indication of locality but probably taken in or near the region 

 suggested. The description is drawn from the female, the sinus 

 of the fifth ventral being small, deep and rounded. In the male 

 the body is smaller and narrower, with the elytra narrowed grad- 

 ually from the humeri, the antennse rather longer than the head 

 and prothorax, with the last three joints scarcely as thick, the 

 ninth a little lono^er than the tenth but each much shorter than
