OP NATURAL HISTORY. 649 



Var. £. — Elytra with dull ferruginous spots. Arkansaw. 



It appears to be an inhabitant of nearly all parts of the Union, 



COPRIS Fabr. 



1. C. COLONICA. — Thorax somewhat retuse; head with a short 

 elevation between the eyes. 



Inhabits Mexico. 



Body black ; head a little rugose, with a slightly elevated, com- 

 pressed, rounded horn, broader than high, situated between the 

 eyes and not surpassing the line of [175] their anterior canthi ; 

 tip of the clypeus rather acutely rounded ; thorax somewhat ab- 

 breviated dorsal line behind the middle, and a deeply indented, 

 oval impression on the middle of the lateral margin ; punctures 

 small, very numerous ; elytra with indented, punctured strise ; 

 interstitial spaces convex. 



Length nine-tenths of an inch. 



Resembles C. Carolina Fab., but is not so robust, and the tho- 

 rax is much less elevated behind. The horn of the head, also, 

 in Carolina is equidistant between the eyes and the tip of the 

 clypeus. It is also like Nicanor ? as figured by Drury i. pi. 35, 

 fig. 1. 



2. C. INCERTA. — Thorax simple, with an impressed line ; head 

 horned ; elytra striate. 



Inhabits Mexico. 



Body black, somewhat polished ; head with dense, shallow 

 punctures ; a short, conic, vertical horn on the middle ; tip of 

 the clypeus acutely and rather deeply emarginate ; thorax punc- 

 tured except on the posterior disk ; a deeply impressed line from 

 a little before the middle to the base, and an impressed oval spot 

 each side ; anterior margin rather abrupt ; elytra with deeply 

 impressed, crenate striae; interstitial spaces convex, impunc- 

 tured.- 



Length nearly seven-tenths of an inch. 



I should be inclined to consider this as as the female of the 

 procichia nob., but in that species the larger horn is very near 

 the anterior termination of the head, and the posterior horn is 

 much shorter and remarkably inclined ; whilst in the present in- 

 sect no tubercle exists to mark the locality of the larger horn, and
