Rh others Dr. Christophers sends me have the T-spot badly developed ; others have the first and second large spots united on the costa.

In any batch of A. Rossii caught at Calcutta, it seems from the joint letter of Captain James, I. M.S., and Drs. Stephens and Christophers, several variations from the type may be found.

It appears this common Asiatic species does not take part in the distribution of malaria.

Thorax pale ochraceous-brown, with pale golden hair-like curved scales and black bristles ; palpi dark brown, with yellowish-white apex and two other pale rings. Abdomen dark shiny-brown, densely clothed with golden-brown hairs ; venter pale ochraceous. Legs dark brown, almost black, a small yellow spot at the apex of the tibiaj and femora. Wings with costal border marked with four prominent black spots and a small basal one; wing-fringe dusky, with three yellow patches, namely, at the ends of the lower branch of the fourth and the two branches of the fifth.

Length. 3 to 3'5 mm. Habitat. Madras.

Observations. I have seen only a single specimen of this insect. It is very similar to Grassi's A. superpictus, but much smaller, and has no tarsal banding.*

Thorax dark brown at the sides, paler in the middle ; abdomen deep brown, with scattered pale hairs. Legs dark brown, unbanded. Wings with the costa black, including the actual base, with four small distinct yellow spots, the largest light area being that quite at the base ; fringe dark, except at the apex, and indistinct paler patches opposite one or two of the longitudinal junctions. Palpi of V black, with two narrow rings and a minute white tip ; in the <$, black with two whitish bands. (Fresh specimens show three fringe spots.)

Length. 3'5 to 4 mm.

Habitat. Ellichpur, Behars ; Etawah, N.W.P.

Observations. This and my A. Christophersi are very closely related, "but can easily be separated by the difference in the banding of the palpi.

A. Indicus is the same. This name must therefore sink as a synonym, as Col. Giles described Listoni and culicifacie* a month before my Indicut. Giles's $ culici- fades is the same as Listoni, so that both names sink under culicifacies, as the latter was described first.
 * Having recently examined a fresh series of culicifacies, I am convinced my
