Scaritides. 



The most remarkal)le peculiarity in this sub-faiuily is the wide space between the thorax 

 and abdomen, by which the latter appears pedunculated : the posterior angles of the 

 Ibrmer are also so rovuided, that its form is lunate. The antennse are short, moniliform 

 and the first joint is the longest ; the head is large ; the tibije of the anterior leo-s are 

 broad and dentated, having the appearance of being palmatcd. The mandibles are large 

 and powerful, and armed with broad teeth ; labrum short, entire or dentate, sometimes 

 trilobate ; mentum trideutate, with the middle tooth strong ; labial jjalpi two- and four- 

 jointed. 



The scaritides are carnivorous, and in this respect bear a close resemblance to the allied 

 subfamilies : some living in the ground, upon other insects or their laiTje ; and some 

 freciuenting the seacoast, burrowing in the sand, and living upon the dead carcases of 

 shrimps. In this State, they biurow in the ground, or live under stones. A-ferge-sj>ecies

ScAHiTEs suBTERRANEi's (Fab.). ( Plate xvill fig. 14.) 



Color black ; thorax marked with a fine central line. Thorax and head equal tlie abdomen 



in length, the latter supported on a short i>eduncle. Length eight-tenths of an inch. 



The insect, in consequence of its pediuiculated abdomen, apjioaSs as if bisected. It is a 



iii>ctunial feeder, and is found <juite abundantly in Central New-York. Its singular form 



renders it easy to be distinguished.
