A NEW HOT-FLY FROM REINDEER. 



[DIPTERA; MUSCOIDEA.] 



BY FREDERICK KNAP,. 

 Bureau of Entomology. 



A bot-fly of reindeer, whose larvae inhabit tumors under the 

 skin, has been long known. The species is now designated as 

 (Edemagenn tarandi (L.). Since 1736, when Linne first de- 

 scribed it from Lapland,* the fly lias been frequently reported 

 from northern localities of the Old World, and a number of 

 times from the boreal regions of North America. t Specimens 

 before me from Alaska agree with those from the Old World, so 

 that there can be no doubt that the species is circumpolar. 

 (Edemagena tarandi may be said to be very well known and has 

 until now stood alone in its genus. The discovery of a second 

 species of the genus, also from reindeer, is therefore rather sur- 

 prising. The new species is evidently confined to Newfound- 

 land, where it infests the reindeer peculiar to that island 

 ( Rangifer terra nora Bangs).
