1925] North American Varieties of Volucella bombylans Linn 11 
Volucella bombylans evecta var. sanguinea Will. 
V. evecta var. sanguinea Will., Synop. N. A. Syrphidse, p. 
186, 1886. 
Specimens of evecta referable to this variety are rare. A 
specimen received from Mr. A. B. Champlain, taken at Charter 
Oak, Pa., July 11, 1917 (H. B. Kirk), has a dorsal patch in the 
third and the greater portion of the fourth segment with red 
pile. A specimen from Sherborn, Mass., June 13, 1913 (E. J. 
Smith), has a large patch of red pile on the third segment while 
the pile on the fourth and fifth segments is yellow. This variety 
will have to be restricted to those with red pile on the third seg- 
ment. It represents — in a way — a parallel variation to that of 
rufomaculata in the subspecies facialis, but lacks the red ground 
color.
