 quartia) . 



Townsend, Proc. Biol. Soc. Wash., xxviii, 1915, 22, notes mis- 

 identification by Coquillett. 



I examined the type in the University of Kansas. It is a 

 female, not a male as stated by Townsend, and seems to 

 differ from pristis mainly in having three sternopleurals and a 

 more yellowish cast to the pollen over most of the body. 

 Coquillett misidentified it and described it again as Bxorista 

 isae, as I find from the type ; his specimen is teneral and hardly 

 shows any yellowish tinge, the shrinking of its head has brought 

 one pair of frontals a little below the apparent level of the 

 antennal insertion, which probably induced Coquillett to refer 

 it to Bxorista. 



Represented in the National Museum only by the type of 

 isae.
