Immature stages of Leptogaster species have been 

 discussed or described by Beling (1875, 1882) and 

 Malloch (1917) ; Melin (1923) illustrates and describes 

 larva and pupa of Leptogaster cylindrica De Geer 

 (1776).

Subgenus Beameromyia Martin 



Beameromyia Martin, Bull. Amer. Mus. Nat. Hist., vol. 3, 

 p. 355, 1957. Type of subgenus: Leptogaster pictipes Loew, 

 1862, by original designation. 



Distinctly small, slender flies with the typical facies 

 of Leptogaster Meigen. They are characterized by 

 the scanty band of fine, erect hairs across the middle of 

 the second abdominal tergite; not well developed in 

 all species, and by the nearly rectangular relationship 

 of the upper, anterior intercalary vein to the first branch 

 of the medius. Head, antenna, and thorax as in 

 Leptogaster Meigen. Hind femur unusually stout 

 towards the apex, the hind tibia unusually robust and 

 swollen, but towards the base as narrow as the base 

 of the hind femur. Empodium stout and three-fourths 

 as long as the claw. Wing with the anal cell widely 

 open. Last branch of radius nearly straight, the ante- 

 rior branch of the third vein rather strongly arched. 

 Male terminalia with primary, secondary and tertiary 

 penis valves and a median process beneath the valves. 

 Length 4y 2 to 8 mm. with the majority of the species 

 being 6 to 7 mm. in length. 



Head, lateral aspect: The head is very much as in 

 Leptogaster, the face scarcely appearing at all in pro- 

 file and only minutely above the epistomal margin. 

 Occiput rather well developed on the middle of the 

 profile but only towards the middle of the head. It 

 bears submarginally a few fine hairs, some of which 

 extend deeply inward. From the dorsal aspect the eye 

 retreats rather strongly anteriorly leaving much of the
