Wyoming : Female, Douglas. 



This species exhibits a remarkable variation in size throughout ita 

 entire range. The females vary in length from 5 mm. to 14 mm., 

 while the males vary in length from 5 mm. to 13 mm. The types of 

 nmcer, adtnetus, and a'pachea have been examined and found to 

 agree with this species. While it is possible that more than one 

 species is represented in the material examined I have been unable to 

 find any evidence that such is the case. Bradley (1916) pointed out 

 that the females from the East have the legs slightly darker than 

 specimens from the Middle and Western States, but there does not 

 seem to be any good evidence for considering this character as spe- 

 cific. The type of apachea is similar to small specimens of obscura 

 from both the Middle and Eastern States.

SPECIMENS EXAMINED 



New Mexico: Male, Albuquerque, July 19, 1902 (Oslar) ; male, Albuquerque, 

 1894 (F. H. Snow). 



This species is closely related to obscura but may be separated from 

 it and other related forms by the characters given in the key. This 

 specimen has been compared with the type and found to be identical 

 with it. The genitalia are like those of obscura and are therefore not 

 figured.
