Rh The only other unhanded legged Indian species related to it are A. Listoni, Giles, A. culicifacies, Giles, and A. Turkhudi, Listen; the first has the largest right costal area at the base of the wing and the forked scales of the head mostly dark in the ? , and the ? palpi with two narrow rings and a minute white tip. A. culicifacies has only three pale fringe spots.

A. Turkhudi differs in having the apex of the palpi black in the $>.

A. Christophersi is abundant in the malarious district of Duars, and is a prominent malaria bearer.

" Thorax covered with white scales on a dark background, scales so arranged as to show a median and two rather less distinct, lateral, darker, longitudinal markings. Lateral aspects of the thorax covered with brown scales, often tipped with white. Abdomen dark olive- green colour, covered with many light yellow hairs. Legs dark scaled, except for a few yellowish-white scales at the distal extremities of the femora and tibiae. Proboscis dark, yellow at tip. Palpi with black scaled tips, and with three white scaled bands on each ; wing with six white scaled portions to the costa, one at the apex of the wing ; the first long vein has five white areas corresponding with the five outer white ones on the costa, in addition a small white interruption at the position of the marginal transverse vein; fringe with pale interrup- tions, except at the sixth vein.

" Habitat. Ellichpur. Time of Capture. March and April."

Note. I have not seen this species. It is described by Captain Liston, I. M.S., and seems clearly distinct. Unfortunately no measure- ments are given in his paper. The figure given shows the tarsi banded with narrow pale bands, thus differing from the description in the text. The black -tipped palpi should easily enable the observer to identify this Anopheles.
