and mesosternal epimera and the presence of a mandibular scti- 

 gerous puncture, the form of the liguUx and paraglossa; and the 

 structure of the abdomen. 



The raesosternuni is not narrow between the coxae but eniargi- 

 nate receiving the metasternuui and in this respect diO'ers greatly 

 from the Oza^nini which have the mesosternuui, at most, linear 

 between the cox® and never wide enough at tip to be eniarginate. 



Nomius contains but one species N. pijgmseus Dej , which 

 occurs in various parts of southern Europe, and in many places 

 in our country from Georgia to California and Lake Superior. 



It occurs under stones, etc., in moist places, and exliales a 

 strong fetid odor.
