SuBFAMILY CALLIPHORINAE 931 
Adults may be collected in large numbers upon flowers of wild 
parsnips in Ohio during July. They are attracted to fresh 
human excrement sometimes, but most frequently to freshly 
exposed meat and are one of the most abundant green flies on 
freshly killed animals. The larvae are found most frequently in 
carrion. 
Kingsecote (1932) reports that larvae of this species often 
kill young foxes in two or three days by causing subdermal 
myiasis, but it is probable that another species may be concerned.

All the known species of Phaenicia in North America have 
the following characters in common. 
Male and female. Head (pl.5,C) with epistoma warped a little 
forward from clypeal plane and nearly as wide as clypeus; meta- 
cephalon short and only slightly produced behind; inner vertical 
bristles decussate or reclinate; ocellar triangle hardly reaching 
one-third the distance to the lunule; clypeus well-depressed, 
slightly concave; facial carina absent or apparent only in a 
short narrow low keel between the first antennal segments; 
faciale slightly convex in profile and usually bristled only at 
vibrissa; vibrissae above oral margin and well-separated; pro- 
bosecis two-thirds to three-fourths head height; palpus clavate; 
antennae inserted at or slightly below eye middle when head is 
viewed in profile, their bases approximated; arista with penul- 
timate segment short, terminal segment elongate, with long cilia 
above and below nearly to apex; back of head flat or slightly 
depressed. 
Thorax usually with three humeral bristles and a weaker 
fourth bristle anterior to these; propleural bristle strong; pre- 
intraalar bristles three, the foremost bristle usually weak; pro- 
sternum large, wide, setose; postalar declivity setose; preparap-
