the lobe is straighter or less curved than internal to the lobe, resulting

Wister, Oklahoma, August 2 and 4, 1907: 15 males, 17 fe- 
males, Frank Collins; all in collection of E. B. Williamson. 
When this material was studied and the differences detected, 
specimens were sent to Dr. Calvert for his opinion. He kindly 
separated the appendages of several males and returned these 
specimens to me. In his opinion they are specifically distinct 
from the material which we identify as moesta and putrida, 
and it is at his suggestion that I have described them as new. 
The material on which the preceding study is based is in my 
collection and is as follows:
