Rh

Thorax ashy-grey in the middle, a dark brown stripe on each side, with three dusky median lines and golden hair-like scales. Abdomen black, with numerous pale and dark hairs. Costa black, with one creamy patch near the apex ; veins mostly black scaled ; legs black ; posterior femora with a broad white band in the middle.

Length. 4'5 mm.

Habitat. Bakloh, Punjaub; Naini Tal; Kurseong (Darjeeling) Mussoorie.

Observations. A very distinct species, at once told by the broad white band on the posterior femora.

This genus resembles Megarhinus, but the ? palpi are short and thick, and three-jointed. Several species described as Megarhinus will have to come in this genus, including the Indian species.

This large mosquito, called the elephant mosquito, can at once be told from other Indian Culiddce by the caudal tuft. Walker described it as a Megarhinus. Not having seen the ? (as I imagined) when my recent monograph of ' Culicidse ' went to press, I included the $ in that genus. The ? 's have short palpi, and thus the species comes in my genus Toxorhynchites, There is considerable variation in the leg banding. The ? specimens I described as M. Gilesii I now find are only Walker's species immisericors.

Habitat. Travancore ; Trincomalie, Hot Wells ; Ceylon ; Celebes ; Mysol ; North Ceram ; Weigiou ; Sikkim ; Burma.

This genus can at once be identified by the curious twisted scales, giving the insects a mouldy appearance.
