Rather small; yellowish brown to blackish, with three rows of yellowish-gray 
spots on abdomen, the median spots, at least, forming a parallel-sided stripe; 
frons widened above: wing, including costal cell, hyaline. 
Female.—Length 10-15 mm. Eye bare, purple, with a broad, diagonal, green 
stripe from inner angle to near outer margin, slightly turned upward outwardly, 
and a V-shaped mark above, the apex near end of lower band, the lower arm 
from top of basal callus, the upper arm broader, parallel to upper margin of eye 
and about its own width from margin. Frons yellowish gray, slightly over four 
to five times as high as width at base, distinctly widened above; basal callus 
dark brown to black, square or slightly higher than wide, not quite touching 
eyes; median callus a slender, often lanceolate, concolorous streak, about as long 
as basal callus and usually joined to it: subcallus and top of genae concolorous 
with frons, the subcallus often somewhat denuded on lower half. Antenna 
orange, the first two segments with black hair; third with a distinct dorsal 
angle and shallow excision; annulate portion usually slightly shorter than basal 
portion. Clypeus and lower genae white, with white hair. Palpus creamy 
white, with mixed black and white hair, the second segment moderately swollen 
basally and tapering to a rather slender apex. 
Mesonotum gray, with erect black hair and recumbent pale-yellowish hair: a 
faint indication of stripes in the usual pattern: prescutal lobe distinctly reddish. 
Pleura, sternum, and coxae gray, with white hair, the tufts under wing base 
tinged with yellowish. Wing hyaline, including costal cell, the veins dark 
brown. Femora gray, with pale hair, the apices of middle and hind femora 
yellowish; tibiae yellowish, with concolorous hair, except black apical half of 
fore tibia and some black hair on hind tibia forming a sparse fringe; tarsi dark 
orange brown to black, the fore tarsus darkest. 
Abdomen above brownish black, with a median, parallel-sided, yellowish or 
whitish stripe and, at each side, a row of sublateral, more or less sharply defined 
spots, contiguous with one another and either somewhat oblique to form an 
irregular stripe or quite regular; venter yellowish brown, with some blackish 
apically. 
Male.—Areas of large and small facets sharply differentiated, the large facets 
extensive and upper surface of head distinctly flattened. Body coloration essen- 
tially as in female, the darker portion of abdomen not quite so dark.
