DEER FOREST FLY. 39 
very glossy; of these I unfortunately lost one, but from the other the 
figure given at 5, p. 84, is taken. The general form was, as will be 
observed, elongate heart-shaped, or oval, slightly concave at the larger 
end, and the other bluntly produced, so as to resemble a cap or plate 
with a few raised markings running from the edge to the centre. The 
central portion of the side figured was noticeably elevated for most of 
the length, and on each side of this central swelling, between it and 
the edges of the puparium, was a row of little pits or depressions (see 
figure). The other side was flatter, and the little pits not so noticeable. 
On gently pressing the puparium (on November 4th) it cracked 
open, and I found the insect within, lying with its head towards the 
concave end, its tail towards the convex somewhat produced extremity. 
The eyes were very large, and the wings, which were not as yet in- 
flated, but lying as mere strips one on each side of the fly, reached. to 
about two-thirds the length of the abdomen. The abdomen was shrunk, 
but from the pointed form of the extremity, as examined under both a 
two-inch and one-inch focus-glass, it did not seem to me to be open to 
doubt, although not as yet fully developed, that it was a male. 
The above observations, which I merely submit as being such notes 
of the amount of wing development of the female of L. cervi in this 
country as I have been able to procure to accompany my previous 
notes of the infestation in the same locality, appear to me to show that 
in every instance the female had some amount of wing presence. It 
might be quite abortive, and consisting merely of short distorted veins 
with a little wing membrane at their sides, or it might be just a short 
piece of what appeared to be the lowest part of a healthily-formed wing 
from which the rest had been torn away by some agency removing it 
by a more or less straight fracture across the wing. In no instance 
was the female totally without any representation of wing like the 
male fly when its wings are wholly gone, as figured at p. 35. 
If we could procure a supply of puparia and develop the perfect 
insect, we should of course gain much information on this interesting 
point. But failing this, it seems to me that if we could but get 
puparia from the coat of the Deer, or possibly where the Deer had been 
lying, we might make a great advance by anatomizing them. As the 
time for the appearance of the fly out of its chrysalis or pupal case 
drew near (possibly towards the end of June or during July), we might 
by careful manipulation crack open the case so as to secure the con- 
tained imago, and, if fortunate enough to have female specimens, be 
able to note their condition exactly.
