1910] Lovell—Prosopidide of Southern Maine 185 
I have taken one male at Waldoboro on an umbelliferous plant, 
July 14, which agrees with the description in all respects except 
that there is a small spot on each tegula. From Falls Church, 
Va., from Dr. Nathan Banks, I have one male and two females. 
In all three specimens the tegule are unspotted. The face-marks of 
the 2 are bow-shaped and the collar is dark as in P. variifrons, 
but the mark on the clypeus is absent. The anterior and inter- 
mediate legs are wholly black, but the posterior tibie, are ringed 
with yellow. The ruge of the enclosure upon the metathorax are 
longitudinal.

Female taken on the wild rose, July 10, 1905; and on Aralia 
hispida. The type locality is Hudson’s Bay. A widely distri- 
buted species also reported from Colorado and New Mexico. I 
have a female from Point Abbaye, Mich., July 10, and a male 
from Pequaming, Mich., July 1, both collected by Morgan Hebard. 
The form of the dilated scape in the male is very remarkable, 
but no explanation of its ecological significance seems ever to have 
been suggested.
