They axe, with few exceptions, predaceous beetles ; thej^ are 

 runners, the hind wings being often absent. Their colors are 

 dull metallic or blaclc. They run in grass, 

 or lurk under stones and sticks, or 

 under the bark of trees, whence 

 they go out to hunt in the night- 

 time. They may be found also 

 in great numbers under the debris 

 of freshets and under stones in 

 the spring.

 the same situations as the beetles, and are 

 generally oblong, broad, with the terminal 



ring armed with two hornj- hooks 

 or longer filaments, and with a 

 single false leg beneath. 



The genus Omoi^liron, remark- 

 able for its rounded convex 

 form, and wanting the scutelhim, 

 is found on the wet sands by 

 rivers and pools, where also Eki- 

 2)hrus occurs, which somewhat

 slightly emarginate anterior 

 tibiae, with large prominent eyes,

late holes on the elytra. The 

 genus Calosoma is well known, 

 being common in fields, where it lies 

 in little holes in the sod, in Avait for its 

 prey. 1 have seen C. calidum Fabr. 

 (Fig. 360) attacking the June bug 

 (Lachnosterna fusca) tearing open 

 its sides. Its larva (Fig. 361) is 

 black. C. scrutator Fabr. (Fig. 362) 

 is a still larger species with bright 

 green elytra. It is known, accord- 

 ing to Harris, to ascend trees in search of canker-worms
