compressed; intermediate and posterior tibiae inflexed, the latter 

 more strongly than the former, and provided with two spurs in- 

 wardly, they have two grooves in the outer side divided by a serrate 

 line, the posterior tibiae are crenulate inwardly, in some species 

 sometimes in both sexes, or are simple, the intermediate and posterior 

 tarsi are moderately long, and the joints are triangular, elongate, but 

 compressed, and a little more bristly inwardly than outwardly. 



The habits of Epirinus are the same as those of Scarahceus, but 

 the balls they make are not quite so large in proportion to their size. 

 I have only observed E. scahratus and E. ohtusus making them, but 

 E, liilaris is only found in decaying leaves or vegetation.
