Extends from British America to Virginia, 

 and westward to Iowa. In the middle Atlan- 

 tic States it is the most numerous in specimens 

 of any species of the genus. 



As stated above, it is doubtful whether 

 Haldeman's figure 6 should be applied to this 

 species, even figure 5 being broader than the 

 average of specimens, which is better repre- 

 sented by my fig. 1, which Frauenfeld has un- 

 fortunately described as distinct, being misled 

 probably by Haldeman's illustrations. 



Neither of Mr. Lea's species differ from 



usual forms of Umosa.
