This species has not been recognized thus far, but, from 
the description and the host, it is evidently quite distinct 
from any of the foregoing. If Weyenbergh’s measure- 
ments are correct (spread of wings, 2.5 cm., corresponding 
to a wing length of 10 to 11 mm.), the large size alone 
should enable one to recognize it.

The length of the wing (7.5 to 8 mm.) places L. rapta- 
torum in the group here under discussion. It is probably 
either L. fusca (Macquart) or L. nigra (Peyty), both of 
which are found on birds of prey. The original description 
is insufficient to decide the point, but the probabilities are 
rather for L. fusca.
