DIPTEROUS INSECTS OF THE FAMILY ANTHO- 



MYIID-ffi FROM THE PRIBILOF ISLANDS, 



ALASKA 



BY 

 J. R. MALLOCH 



University of Illinois 



The species given below are those contained in the collection 

 made on the Pribilof Islands by Dr. G. Dallas Hanna in 1920. 



ANTHOMYIID^E 

 The number of species of this family in the collection is rather 

 small, but contains some new ones. I notice all of them, because 

 some have not previously been recorded from the Pribilof Islands. 



1. Mydaea rugia Walker 

 One female, St. George Island, July 1, 1920. This is the first 

 female of this species that I have seen, but I am positive of the 

 identification. I have previously seen males from New England 

 where it is not uncommon. 



2. Eriphia cinerea Meigen 

 The genus, Eriphia, has not previously been recorded from 

 this country. It is represented in the material before me by two 

 males and one female which do not agree in every respect with 

 the European example of the male which I have ; but they prob- 

 ably belong to cinerea Meigen, which is the genotype and only 

 species. 



Eupogonomyia Malloch, new genus 

 This genus differs from Pogonomyia in having the prealar 

 bristle absent or minute ; the hind tibia in male with fine setulose 

 hairs instead of strong bristles on posterodorsal surface, and 

 its apex produced on ventral side ; fore tarsus short and stout, 

 with two or more bristles at apex above on fourth segment ; hind 

 tarsus with two outstanding short bristles near base on ventral 

 surface. The pteropleura is bare.
