Muscina pascuorum M eigen in America

Later he writes — “I found Muscina pascuorum in an attic at Morris- 
town, N. J. , Oct. 19, 1925, 1 have seen no males, but two females from 
New York and one from Morristown, that I dissected, all had 
active sperm in their receptacles. Evident^ the females mate 
before they come indoors to hibernate.” 
The distribution of this species is probably much greater 
than has been recorded. It is readily overlooked as many of the 
species of Muscidae are similar in appearance and have the same 
habit of entering houses as the weather becomes cool in the fall. 
Its life history in America is still unknown.
