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 : 



Argia moesta.
