le apical half is white beneath, but above, the white is confined to the 
nmediate apex; the white band on the tibia is broader than on the mid 
j ,gs; the metatarsus and first two tarsal joints broadly banded white; 
.st two tarsal joints entirely white, ungues equal and simple. 
Abdomen .—Clad dorsally with purple-black scales. In some specimens 
lere is a band of white scales at the base of each segment after the first, 
ut the other specimens shew very imperfect basal bands there being but 
few scattered scales on the segment except the penultimate which 
lways shews a large white basal spot. There are large square basal white 
pots laterally and the venter shews white basal bands except on the last 
vvo segments. 
Male Head .—Similar to the female. Antennae plumose the plumes being 
urplish-black, and the joints are black where the plumes are inserted pale 
t the apex. Palpi about as long as the proboscis slender and without 
ristles, black scaled except for a patch of white scales on the upper sur- 
ice near the base of the first apparent joint and white basal bands on the 
econd and third joints. In all other respects the male resembles the 
emale. 
Occurrence .—Larvae taken from water in bamboos. Adults numerous 
n bamboo jungle. 
Remarks .—In some respects the banding of the thorax resembles 
5 . Fasciata but it lacks the crescentic bands at the sides these being re- 
>laced by a straight line of white and a mass of white scales over the 
oots of the wings. The two central stripes end at a line joining the wing 
oots and do not run right back to the scutellum. The. banding, of the 
find leg is quite different for in Gracilis there is a band in the middle of 
he tibia not present in Fasciata and the two last tarsal joints on the hind 
eg are pure white in Gracilis only the last being white in Fasciata. 
firacilis is also much more slenderly built. 
Stegomyia Perplexa. n. sp. 
Head with a broad white central band and narrow lateral white bands 
vith black scales between. Basal joint of antennae white scaled and palpi 
vvith snowy-white tips. Thorax black scaled with a median line of silvery- 
white scales broader in front than behind and a broad margin of snowy- 
white flat scales and a few broad flat spatulate scales write in colour at the 
base of the scutellum in the middle line. Middle lobe of scutellum white 
scaled. Abdomen clad with black with basal white bands and large lateral 
spots. Legs black with one white band on the fore leg two on the mid 
ind two on the hind, the two last hind, tarsi pure white. 
Female Head— Clad with large flat scales with truncated ends arranged 
as follows:—In the centre a triangular patch of white broadest at the 
vertex narrowing on the occiput and ending before it reaches the margin 
of the occipital foramen, on either side of this a broad band of black 
scales succeeded by a narrow band of white followed by black and again 
by white ; a narrow band of white narrow-curved scales runs along the orbital 
margin of either side; behind on the nape are two or three rows of black 
upright scales difficult to see unless the head is bent downwards to expose
