They are, with few exceptions, predaceous beetles ; they are 

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

 dull metallic or black. 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. 

 Fig. 36i. The i arvae are found in much 



the same situations as the beetles, and are 



generally oblong, broad, with the terminal 



ring armed with two horny hooks 

 or longer filaments, and with a 

 single false leg beneath. 



The genus Omophron, remark- 

 able for its rounded convex 

 form, and wanting the scutellum, 

 is found on the wet sands by 

 rivers and pools, where also Ela- 

 plirus occurs, which somewhat 

 resembles Cicindela. It has 

 slightly emarginate anterior 

 i- tibiae, with large prominent eyes, 

 and rows of large shallow ocel- 



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 wait for its 



prey. I 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- a Fi s- 363t 



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

 Carabus has similar habits, but differs in having the third
