Extract

Dactylopius sorghiellus, Forbes. Syn. D. Kingii, Ckll.

Dr. S. A. Forbes has kindly sent me the type material of this species, which I have examined with much interest. The material studied consisted of 4 specimens. As is usual with these subterranean forms the antennæ are quite variable, both in the number of segments and their relative length.

Only two of the antennæ of the 4 specimens were 8 jointed, the others being 7-jointed, and some plainly aborted. After careful measurement and study, I conclude that the forms described by Cockerell in Science-Gossip, Feb., 1897, p. 240, as D. Kingii, must be referred to this species.
