to the base of the eyes ; base of head thick, curvedly contracting to base of occiput, surface next 
to inner line of eyes incised; front vertical, forming a rounded lobe as far as to below the 
middle of the eyes; tylus short, tapering and curving beneath, a very little more prominent than 
the front; rostrum pale green, slender, reaching behind the posterior coxae. Antennae long and 
slender, pale green or yellowish, the basal joint longer than the head, sometimes a little dusky 
at tip, the second joint cylindrical throughout, a little longer than the pronotum and seutellum 
united, third joint a little more slender and about two-tliirds the length of the second, the 
fourth still more slender, very short, sometimes a little dusky. Pronotum nearly trapeziform, a 
little wider than long, gently sloping anteriorly; the lateral margins sinuatod directly before the 
prominent humeri; surface a little uneven, the callosities distinct and with an indented space 
between them, the impressed line behind them deep and clearly defined, arrested by the thick 
carinate lateral edge which stops against the end of the callosities; the anterior angles rounded 
off, the anterior edge a little sinuated, callous, extending to about the middle of the eyes; 
posterior margin a little yellowish, hardly sinuated. Cdavus and corium minutely scabrous, 
almost transparent, very ample as compared with the abdomen; cuueus long, bordered exteri¬ 
orly with a thick green line; membrane very thin, whitish green, the vein deeper green. Legs 
greenish, the tibiae sometimes yellowish, dusky at tip ; apex of the tarsi and the nails piceons. 
“Length to end of abdomen 2.25-2.5 mm. To tip of membrane 3.5 mm. Width-of pronotum 
1-1.25 mm. Numerous specimens have been brought to my notice. The first of these I found 
near Montmorency, in the province of Quebec, others weye obtained near Washington, D. C , by 
my friend Otto Heidemann, and a male specimen has been sent from Colorado. The specimen 
from Colorado has the callosities near together on their inner ends.”
