206 SEVENTEENTH Report STATE ENTOMOLOGIST OF MINNESOTA—1918 
These are large powerful Hymenoptera, usually hairy, black, 
generally with bands or spots of red and yellow. Some of the species 
prey upon the larvae of lamellicorn beetles, the female Scoliid pene- 
trating the ground to find the lar- 
vae. Tiphia inornata, ‘shiny, 
black, 1s parasitic on white grubs. 
Numerous wingless forms occur 
in the family, the larvae living 
parasitically at the expense of 
other Hymenoptera.

males and have short antennae, 
while the males are long 
with slender antennae, and 
the radial cell, unlike that 
in the female, touches the 
costal margin of the wing. 
This genus is quite com- 
monly seen on the flowers 
of golden rod and on flow- 
ers of umbellifers. Elis 
quinquecincta Fab. and 
Campsomeris plumipes 
Drury, occur in this state. Fig. 93.

SAPYGIDAE 
Females winged. Wings, when present, not folded longitudinally in repose: a 
constriction between first and second abdominal segments; legs as in Seoliidae; ster- 
nellum not defined; intermediate coxae usually contiguous; tibiae not flattened; apex 
of abdomen in male without appendages; eyes deeply emarginate; abdomen usually 
marked with yellow or white. 
All species said to be parasitic though some are reported as 
guests in the nests of some bees. The genus Sapyga has smooth slen- 
der body ornamented with yellow; it lays its eggs in the cells of Osmia, 
the larva consuming the stores which the latter has laid up for its 
young. One species of Sapyga has been bred from Pelopaeus cemen- 
tarius.
