In the little gall-midges the antennae are many jointed and 

 often with whorls of hairs. There are usually three longi- 

 tudinal veins and the costa continues around the wing. 



The family is an immense one and the larval habits vary 

 somewhat. A great majority of the species cause abnormal 

 growths on plants and some are recognized by their galls 

 alone. 



Scarcely any material was taken in this family, most of 

 that sent to Dr. E. P. Felt being probably undescribed. More 

 specimens will be required before the identification of the 

 species of Lestremia, Prionellus, Rhabdophaga and Lasiop- 

 tera can be made with certainty. A female of a species of 

 Lasioptera taken near Forest Grove has 36 antennal seg- 

 ments, more than have been recorded from any other Amer- 

 ican species according to Dr. Felt.
