 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 

 tliey 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 s^jring.

 generall}^ oblong, broad, with the terminal 



ring armed with two horny hooks 

 or longer filaments, and with a 

 single false leg beneath.

 slightly emarginate anterior
