Length of body 1.6 to 2.2 mm; length of wing 2.5 to 2.9; width 

 of head 0.75 to 0.80. General color light brown to dark chocolate 

 brown or reddish; vertex usually lighter; mesonotum with four 

 stripes of lighter brown usually present; stripes just mentioned may 

 be variable in degree of distinctness; abdomen darker, more or less 

 variegated ; antennae flavous, black at tip ; legs light brown to brown ; 

 wings variable in extent of maculation, from a slight f umate condition 

 in apical portion to a more distinct brown maculation or bands ; some- 

 times the entire wing surface is slightly fumate, with veins dark and 

 prominent. 



Head not quite as broad as thorax; vertex nearly half as long as 

 broad, with two fovese of varying depth and extent; gense somewhat 

 swollen; clypeus unusually enlarged and elongate, projecting forward 

 and downward, cylindrical and truncate. Antennae seldom longer 

 than width of head (this may vary somewhat, however), rather 

 thick. 



Thorax seldom arched strongly, usually rather flat, coarsely 

 punctate. Legs short. Wings variable in size as well as coloration, 

 usually darker in apical half, venation as shown in figure. 



Genitalia. — Male. — Anal valve moderately large; posterior lobe 

 long, converging to apex; forceps rather short, slightly enlarged at 

 apex, inner terminal tooth short. — Female. — Genital segment usually 

 about as long as preceding ventral sclerite, sometimes longer, variable.
