This well-marked species suggests G. enderleini Alexander {annulata 
Enderlein) in its large size and long rostrum, but differs in the wing-

vol. 3, p. 22 (1823). 
This species ranges over the eastern United States and Canada, 
from Maine and Canada to Florida, west to Illinois and Louisiana. 
What has been determined as this species ranges over the Antilles

correct. Knab's records show this species to feed on various Com- 
posite flowers {Eupatorium, Solidago and Helianthus).
