it is distinguished by being proportionately longer and in having the cheeks 

 smaller, as well as by having the sides of the adult hypostome about parallel. 

 O. concanensis is known only from bats and bat retreats and kelleyi from bats 

 and from houses, some of which harbor bats. O. talaje has not been recorded 

 on bats. The resemblance of this species to O. talaje led to its having been 

 reported as talaje in houses in New York, Wisconsin, and Minnesota, by 

 Matheson, 1931, Herrick, 1935, and Riley (1935), respectively. Other records 

 (unpublished) are from houses in Pennsylvania, Illinois, and Iowa. Collection 

 data are summarized in table 7.
