6 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 68 



1921, by Dr. W. M. Mann, in whose honor this strange insect is 

 named. 



Type.— Male, Cat. No. 28291, U.S.N.M., allotype female, and one 

 female paratype ; another female paratype in the writer's collection. 



One of the female paratypes shows a cluster of six gamasid nymphs 

 attached on back of abdomen, between the second and third seg- 

 ments; there is moreover one isolated nymph on venter, between the 

 first and second sternites. This fact may perhaps be considered as 

 an indication of f imicolous habits of the fly ; while on the other 

 hand the physogastric condition of the female is suggestive of some 

 myrmecophilous forms. And the unchitinized abdominal sclerites 

 are very like those observed in Termitoxenia and allied forms.'
