Explanation of Plate XXXIX. 
Pupa of C. ruhi. 
Portions of pupa, chiefly to show hairs, which are almost identical 
with those of C. avis, in my preparations of which they happen to 
be destroyed or absent, enabling, however, the other features to be 
more easily seen. 
Fig. 1. End of prothorax x 80. 
Fig. 2. Portion (dorsal) of 5-6 abdominal incision x 45, to show 
functional intersegmental membrane. It is nearly identical in C. 
avis, but was not so well shown in specimen.
