HADRONEMA Uhler. 



This genus so far as known is represented by a single species, found 

 in the Rocky Mountain region and in Mexico. The larger species here 

 added to it appears to agree better with it than with any other with which 

 T have been able to compare it, though it is doubtful whether it really 

 belongs here.
