460 Dr. James Waterston on Chalcid Parasites. 
larger and smaller examples respectively. These lots 
analyse as follows :—

Smallerexamples .| 12 “A” | 70 175 | ¢.e23 4059

I take it that ““C” and “A” refer to separate pupae 
of Teratoneura. If so the difference im size is apparently 
due to the fact that in the A lot not only was the parasitism 
heavier but the ratio of males to females over three times 
higher. 
(b) Chaleididae—Genus Chalcis. 
Chalcis 2? leighi Cam. (Ann. 8. Afr. Mus., vol. v, 1907, 
p. 210). One 2 from pupa B. 
Cameron’s species rests on the unique and imperfect type 
in the B. M., and a complete comparison has not been 
possible. In your example the puncturation of the hind 
femora is hardly so heavy, nor is the base of the hind 
tibia so pale above as in the Natal insect. But the two 
are extremely close if not identical, as I incline to think 
they will prove to be.
