Phaonia minima Malloch 



Fhaonui inininvi Malloch, Rep. Can. Arctic Exped. 1913-18, iii, pt. C, Insects, 



Diptera, p. 61c, 1919. 



This species is very similar to the preceding, but differs in 

 having no short stout outstanding bristle on posteriordorsal 

 surface near apex, as stated in key. 



Length, 4 to 5 mm. 



In addition to the type and allotype specimens from Nome, 

 Alaska, which, I have before me, I have seen one male from St. 

 Paul Island, Alaska, August, 1910, collected by H. Heath, which 

 belongs to the Leland Stanford University collection. 



I have seen one female which was taken in Montana that is 

 referable to either this or the preceding species, but it is not 

 possible to definitely decide its identity.
