This genus was erected by Scudder for a single specimen found 

 in the Chagrin \^alley, 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 fifth and sixth veins are free. The short nine-jointed antennae 

 indicate a close affinity with Tritozyga O.S. and IMicrocerata 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.
