Mr. F. V. Theobald. On the Culicidce of India,

Anoplieles Christophersi. n. sp.

Thorax brown with narrow curved, long, pale golden scales, slightly darker at the sides. Abdomen dark brown with golden hairs. Legs dark brown, unbanded, and with no knee or other spots. Palpi brown to black, with two broad apical white bands and a narrow one towards the base. Wings with the costa black, with four small yellow spots, the basal one rather indistinct, veins with rather long scales, the black ones being most prominent ; fringe black, with four pale spots.

$ . Head dark brown, with broad white upright forked scales in front, black ones behind, and a dense tuft of white hairs projecting forwards ; palpi dark brown, almost black, densely scaled, with two broad apical bands and a narrow one on the apex of the basal third of the palpi ; antennae bright brown ; proboscis deep brown with pale apex.

Thorax brown, with long, narrow, curved, hair-like, golden scales and brown bristles ; scutellum cinereous-brown with a double row of border-bristles, the outer ones being large, the inner small ; metano- tum deep brown to black.

Abdomen almost black, with golden hairs. Legs completely dark brown with bronzy reflections in the sun ; ungues equal and simple.

Wings (Plate 5, fig. 3) with the costal border black, with four small yellow spots, and the apex yellow, the basal spot very small ; the yellow spots spread uniformly on to the first long vein except the third which passes well under the black costal spot ; scales of the veins mostly black ; a yellow patch at the base of the fork-cells and on most of the third long vein, a long patch at the base and another towards the middle of the fourth vein ; one large and one small patch on the upper and one large one on the lower branch of the fifth vein, the stem mostly pale ; most of the sixth dark, but there is a broad yellow line towards the base ; fringe black, with yellow spots at the end of the veins, except where the sixth joins the costal border ; first sub- marginal cell considerably longer and narrower than the second posterior cell, its base much the nearer to the base of the wing ; its stem about half the length of the cell ; stem of the second posterior about one and a half times the length of the cell ; supernumerary cross-vein about half its own length in front of the mid cross-vein ; the mid more than its own length in front of the posterior. Halteres with pale testaceous stem and black knob.

Length. 2 '5 mm.

Habitat. Duars (Christophers).

Observations. Described from two ? 's sent to the Royal Society.

The species is very closely related to my A. Indica, but has more than three pale fringe spots, and the cross- veins are not the same, being more like A. superpictus, Grassi. The long black basal part of the costa is also very characteristic, as also is the pale third long vein.
