636. Macquartia pristis (Walk.) 

 Corvallis, V-21. 



637. Uramyia acuminata (Bigot) 



Corvallis, bred from Halisidota argentata. This species 

 was described from Brazil and later found in Mexico. Ac- 

 cording to Aldrich, Townsend's Uromacquartia halisidotae, 

 named without description, is a synonym of this species. 

 Townsend's type is the single male mentioned by Coquillett 

 under Macquartia pristis (Revision Tachinidae, p. 64) from 

 Aurora Mills, Oregon, and recorded as a parasite of 

 Halisidota argentata on p. 18. This species, as Dr. Aldrich 

 points out, has reversed the usual trend of distribution on 

 the coast.
