SuBFAMILY CALLIPHORINAE 215 
head width 12.0; front at narrowest (which is about 1.5 above 
lunule) 0.86 of head width, 0.88 at vertex and 0.38 at lunule; 
third segment of antenna 5.4 times as long as second and very 
wide from base to apex. Wing with costal sections 2 to 6 in the 
proportion 80:50:110:40:8. Abdomen with marginal row of bris- 
tles on second segment strongly recumbent, those on third and 
fourth segments more erect. Otherwise similar to male except for 
normal sexual differences. 
Length. 7-8 mm. 
The holotype male and one paratype male are from Old Crow, 
Alaska. A female from Camp 334, Alaska Engineering Com- 
mission, collected by Aldrich on July 12, 1921, one female from 
Mt. McKinley National Park, Alaska (without other data), one 
female from Savonoski, Naknek Lake, Alaska, July, collected 
by J. S. Hine, now in the Ohio State Museum, and three females 
from near Churchill, Manitoba, Aug. 5-6, 1937, collected by R. H. 
Daggy, are presumably the same species. 
Biology, habits, and wmmature stages. Unknown.
