INSECUTOR INSCITI^ MEJNSTRUUS 83 



(Journ. N. Y. Ent. Soc, vol. 26, p. 67, 1918) has pointed out 

 this fact and expressed the possibility of the Japenese insect 

 being the same as the European form. A study of authentic 

 specimens of both species soon revealed the differences above 

 described and the species is consequently renamed as above. 



THE MUSCOID GENERA PSEUDEUANTHA 

 AND URAMYIA 



(Dipt era) 

 By J. M. ALDRICH 



These closely related genera include both neotropical and 

 nearctic species, all of which readily run to Macquartia in the 

 table of genera in Coquillett's Revision of 1897. This use of 

 Macquartia appears to have been the traditional sense, since 

 one of the National Museum specimens placed by Coquillett in 

 M. pristis had already been labeled "Macquartia sp." by Brauer 

 and Bergenstamm. But Brauer himself had restricted the 

 genus to a different group by designating Tachina dispar Fall. 

 as type in 1893 (Verb. Z. B. Ges. Wien, 486) ; this species 

 has the frontals extending below the base of the antennas and 

 the parafacials are heavily pilose. In this restricted sense 

 Macquartia is not North American. 



The two genera herein considered have the following char- 

 acters in common : frontal bristles extending only to the base 

 of the antennas; eyes densely hairy; face receding; vibrissas 

 at edge of mouth, not approximated ; parafacials bare, narrow ; 

 facial ridges with only a few small hairs below ; palpi and 

 proboscis normal ; antennas reaching nearly to vibrissae, third 

 joint about three times the second (two in halisidotcF) , arista 

 slightly or distinctly pubescent. Venation without unusual 

 features, first posterior cell ending somewhat before the wing 

 tip, open, third vein with a few hairs at base. 



The chaetotaxy is strikingly uniform : ocellars directed for- 

 ward but often small, verticals in the male hardly distin- 

 guishable from the postorbital row of hairs, but in the female 

 well developed ; male without reclinate frontals, the female with
