528 TRANSACTIONS OF THE 



Var. a. Sutural edge of the elytra ferruginous. 



I obtained this species in the winter of 1819, when with Major 

 Long's party, at Engineer Cantonment, near Council Bluff. It 

 occurred in considerable numbers, occupying some crevices of 

 rock, eight or ten feet under the surface, in a temporary quarry, 

 where they were hybernating. It differs from cyampenms, Say, 

 found at the same locality, by the different color of the antenna, &c. 



Can this be the Janus, or is the qvadrijiamis Dej. synonymous 

 with that species described in Turton's Linn. ?

1. C. BIPUSTULATA Fabr. — The true species of this author 

 has almost always, if not in every instance, but two spots on the 

 elytra, and these are terminal. The second interstitial line has 

 seven or eight subequidistant punctures, and the fourth interstitial 

 line has five or six punctures, subequal, excepting the terminal 

 one, which is more distant. 



2. C. QUADRiMACULATA Palisot de Beauvois. — This species is 

 quite distinct, though very closely allied to the hlpustulata. It is 

 similar in size and almost so in form ; but the thorax is propor- 

 tionally longer. In color it is generally like the preceding, but in 

 addition to the two terminal punctures of the elytra, their base is 

 more or less, but generally obsoletely, tinged with obscure rufous. 

 The interstitial lines are [416] altogether destitute of punctures. 

 I have a variety in my collection, of which the elytra are entirely 

 of a rufous color and even paler than the terminal spots usually 

 appear; these spots are of course not visible. 



3. C. viRiDis Say, Trans. Amer. Philos. Soc, has been since 

 described by Dejean under the name of rostrata, Sp. Gen. 1, 

 419, but corrected vol. 2, Supp. 478. 



Of this genus I have eight described species of this country.

 1. C. VINCTUS Weber.— I think it highly probable that Dejean 

 is right in considering, as he does, (doubtfully however), my C. 

 interrvpfus to be the same as this. Weber's expression, " lineis 

 elevatis tribus," renders this conclusion highly probable.
