A REVIEW OF THE LARVAEVORID FLIES OF THE TRIBE 
LESKIINI WITH THE SETULOSE FIRST VEIN (R,) 
By Maurice T. James 
In sprre of the fact that certain of them are actually or potentially 
important parasites of agricultural pests, the tachina flies of the tribe 
Leskiini have been neglected by taxonomists. No comprehensive 
treatment of the species has ever been published.” The writer had un- 
dertaken a study of the genera and species of the New World, but, 
seeing that its completion would require more time than he had at his 
disposal, he decided to limit it to the group here under discussion, 
namely, to those genera in which the first vein (R,) is setulose to or 
practically to the apex. So far as known, no Old World genus pos- 
sesses this character. 
Townsend, after keying out on another basis a genus which does not 
concern us, uses the setulose first vein as the first major division of his 
tribe Leskiini. In this section he places seven genera, of which six, 
including two that I am reducing to synonymy, form a closely related 
complex. The seventh genus, Spathipalpus Rondani, is probably not 
a leskiine; at any rate, its relationship to the other six is quite distant. 
Since Townsend has placed it in this tribe, I am including it in the 
generic key, though omitting it from the body of the work. 
The terminology used in this paper is basically that used by Town- 
send; some modifications are made for the purpose of increased clar- 
ity. All measurements were made by a micrometer scale; in some 
eases these differ radically from those stated in the original descrip-
