in the black species. The posterior border of the mesoscutellum is 
rounded and the anterior border is bounded by three straight lines. 
The antenna- are 6-jointed, scape long and slender, pedicel normal, joints 
1 and 2 of the funicle very short, joint 3 about as long as or a little 
longer than the pedicel, club compact, not jointed, subellipsoidal. 
The middle tibial spur is very pronounced, mesoscutar parapsides rather 
small, marginal vein very long, longer than submarginal; stiginal and 
postmargmal short.

Female. — Length, 1.2 mm.; expanse, 2.3 mm.; greatest width of fore- 
wing, 0.41 mm. Pedicel twice as long as thick ; clnb nearly three times 
as long as penultimate joint; head and thorax smooth, shining; meso- 
scntuni with sparse, irregularly placed, and line punctures; mesoscutel- 
lum very faintly shagreened; abdomen perfectly smooth; mesopleura 
at tip faintly shagreened, smooth at base; hind coxae also faintly sha- 
greened; eyes plainly hairy: vertex with rather dense black pile; 
sparse hairs of thorax black; abdomen ovate, as wide as thorax, con- 
cave above. Discal cilia of forewings proximally bordering hairless 
streak much longer and stouter than those on distal side of streak. 
Of these proximal cilia there are only two or three irregular rows, the 
remainder of base of wing being hairless, except immediately below 
marginal vein, and excepting also the normal bristles arising from the 
submarginal. General color black, not metallic; base of abdomen, and 
sometimes apex, yellow brown ; antennae honey yellow. Front and 
middle femora and middle and hind tibia*, dark brown, lighter at 
extremities; front tibiae slightly dusky at base, but in general sordid 
yellow. Hind femora pale sordid yellow; all tarsi light; wiugs hya- 
line: submarginal vein dark brown, marginal much lighter. 
Male. — Similar to female, slightly smaller; abdomen acuminate. 
Proximal cilia bordering hairless streak of fore-wings, consisting of a 
single row for a greater part of the wing width.
