Five Non-gall-making Midges (Dip., Cecidomyidae). 



By E. P. FELT, Albany, New York. 



The members of two subfamilies and one tribe of the third 

 Mib family of our gall midges, make no galls and are of little 

 interest to the students of vegetable deformations. These 

 anomalous gall midges are extremely interesting to the sys- 

 tematist, morphologist and the biologist because in many re- 

 spects they present most interesting gradations between the 

 gall producers and the series of small flies, living for the most 

 part in decaying vegetable matter. 



j The types, presumably, are in the State Museum at Albany.

Prionellus eremi n. sp. 



The male described below was collected at Brainerd Lake, 

 Boulder County, Colorado, by Prof. T. D. A. Cockercll, dated 

 August 28, and forwarded in April, 1918. This species is allied 

 to P. hcspcria Felt and P. latipcnnis Felt, from both of which 

 it may be easily separated by its greater size and the rclativrK 

 longer basal enlargement of the flagellate antennal segment- 

 and the relatively shorter fourth palpal segment.
