DISTRIBUTION 



From material examined : 



Arizona: South Rim Grand Canyon, June 1925 (E. G. Linsley). 



Colorado : Estes Park, Black Canyon, 7,800 feet, July 7, 1937. 



New Mexico: Jemez Springs, July 1919, type series (John Woodgate). 



Host. — Unknown. 



Chamberlin (1926) states that this species is known only from the 

 type, but the species was described from one male and two females 

 collected at the type locality during July by John Woodgate. 



No variation worthy of note has been observed in the few specimens 

 examined except in size, the length ranging from 14 to 17.5 mm.
