Lestremia vernalis Felt 

 1908 Felt, E. P. X. Y. State Mus. Bui. 124, p. 311 



This species was taken in April at Wichita, Kansas, by Mr E. S. 

 Tucker. 



Male. Length 1.5 mm. Antennae a little longer than the body, 

 thickly haired, dark brown; 16 segments, the fifth with a stem 

 one-fourth longer than the subglobose basal enlargement, which 

 latter has a length a little greater than its diameter, terminal seg- 

 ment reduced, narrowly oval, obtuse. Palpi ; the first segment long, 

 rather stout, subrectangular, the second as long and more slender 

 than the first, the third one-half longer and more slender than the 

 second, the fourth twice the length of the third, more slender. 

 Mesonotum dark brown, the submedian lines inconspicuous. Scutel- 

 lum and postscutellum dark reddish brown. Abdomen dark brown. 

 Genitalia dark reddish brown. Wings hyaline, costa dark brown. 

 Halteres yellowish basally, light brown apically. Coxae, femora and 

 tibiae fuscous yellowish, the segments irregularly brownish at the 

 extremities ; tarsi mostly light brown, the distal segments darker ; 

 claws simple, the pulvilli shorter than the claws. Genitalia ; dorsal 

 plate long, broad, broadly emarginate, the lobes separated, broadly 

 rounded. Harpes apparently fused to form one large, convolute 

 organ; style long, slender, broadly rounded. Type Cecid. 1260.

This genus includes a number of small forms remarkable on 

 account of the greatly reduced antennae. These organs in the 

 male are composed of but 8 to 11 short segments, the second being 

 greatly enlarged, subglobose and in general appearance much re- 

 sembling those of the Campylomyzine genus Micromyia. The gen- 

 italia also differ from those of Lestremia. The one female known 

 has very small antennae composed of 10 joints, the second being 

 somewhat enlarged. This insect has been described as M. per- 

 plexa and appears to be closely related to M. di er villa e 

 and may possibly be the female of this species. Type M i - 

 cromyia corni Felt. 



Nothing is known concerning the life history and habits of mem- 

 bers of this genus, though it is presumable that they are analogous 

 to those of allied forms. It is very probable that the various 

 species breed in decaying vegetable matter.
