REPORT OF THE STATE ENTOMOLOGIST IQI2 153 
This genus was erected by Scudder for a single specimen found 
in the Chagrin Valley, White River, Colorado. It is evidently closely 
allied to Lestremia. The illustration of the wing shows that sub- 
costa unites with the margin near the basal third. The first branch 
of media, which in Lestremia has disappeared, joins costa a little 
beyond the middle. The second branch of media joins the margin 
a little before the apex and is united to subcosta by a short, well- 
defined crossvein, evidently the vein present throughout the Les- 
tremiinariae, Campylomyzariae and Epidosariae. The third and 
fourth branches of media which, for convenience sake we have 
designated in this work the fourth vein, is forked as in Lestremia; 
the nfth and sixth veins are free. The short nine-jointed antennae 
indicate a close affinity with Tritozyga O.S. and Microcerata Felt. 
Type Lithomyza condita Scudd. 
This genus, if correctly placed, is the most generalized Cecid- 
omyiid known and must be regarded as a connecting link between 
this group and the Mycetophilidae. 
CAMPYLOMYZARIAE 
This tribe is easily separated from the Lestremiinariae by the 
simple, nearly obsolescent fourth vein.
