AA. 



genera by the much more slender middle and hind tibiae, which, though 

 very slightly expanded at the tip, are not triangularly dilated. The clypeus 

 has prominent teeth at middle. They may be separated as follows: — 

 A. Small species, .25 to .35 in., clypeus 6-dentate, hind tibiae with two 



spurs nigi'icornis, Say. 



Larger species, .40 to .76 in., clypeus bidentate, hind tibiae with 

 one spur. 



Prothorax distinctly granulate Icevis, Drury. 



Prothorax without raised granules, simply 



scabrous chalcites, Hald.

 CoPRis, Geoff. 



The species of this genus do not transport 

 excrement in balls, but bury it in burrows on 

 the spot. The males have the head or thorax 

 or both variously tuberculate or horned, as 

 in O?ithophagiis, from which they differ by 

 the larger size and the absence of bristle- 

 tipped onychium between the claws. The 

 table gives the chief points of difference : 



A. Elytra with eight striae, front of head 

 semicircular. 



Clypeus evenly and densely punctured all around. Size large, 



.52 to .70 in .anaglypticus, Say. 



Clypeus densely punctured at sides, nearly smooth at middle. 



Size small, .32 to .44 in niinutus, Dru. 



AA. Elytra with seven striae, front of head parabolic. Length, .80 to 



1. 10 in ,... Carolina, Linn.

 PhaN/Eus, MacLeay. 

 The single species reported in 

 the Canadian lists is a beautiful 

 insect, with the thorax] 

 [usually coppery-red, the head, in 

 the male, with a long horn. The 

 length varies from .48 to .88 in. 

 It is P. carnifex, Linn. The 

 habits are the same as in Copris.
