Lasioptera echinochloa Felt 

 1916 Felt, E. P. N. Y. Ent. Soc. Jour., 24:181 



This species was reared in August and September 191 5 by Mr 

 C. N. Ainslie from injured or infested stems of crippled plants of 

 Echinochloa crusgalli collected at Elk Point, S. D. 

 The larvae are usually found in numbers in the fibrous, somewhat 

 decayed stubs of the crown and were also taken from the lower and 

 apparently normal portions of the stem. This midge is allied to 

 L. lactucae Felt, from which, it may be easily distinguished 

 by the almost total lack of scales upon the mesonotum.
