502 Records of the Indian Museum. [Vor Vall; 
appear simple unless very closely examined. The ist longitudinal 
vein bent upwards beyond half its length, ending close to tip of 
3rd. The four light veins about equidistant, very slightly sinuous. 
Halteres reddish yellow.

Phora rufithorax, mihi, sp. nov. 
9. Assam. Long. 24 mm. 
Head.—Front ferruginous brown, with three rows of equi- 
distant bristles and a 4th (lowest) row of only the two middle 
ones placed rather closely together. Ocelli on a small blackish 
spot, not appreciably elevated, on vertex. Eyes black, micro- 
scopically pubescent, with a fringe of strong bristles, which in some 
places are longer than in others. Antennae and palpi yellow, latter 
with strong bristles at tips. Two or three bristles on cheek, point- 
ing downwards. 
Thorax.—Bright reddish brown, minutely pubescent; a row 
of six or seven strong bristles along the sides of the dorsum from 
the shoulders to the scutellum, and some others are placed, 
apparently irregularly, on the posterior part of the dorsum. Sides 
of thorax concolorous, with a few short bristles below the root of 
the wing. Scutellum of average size, concolorous, slightly blackish 
at base in the middle, with four strong, equidistant bristles on 
posterior margin. Metanotum reddish yellow at sides, blackish 
behind, lightly grey dusted. 
A bdomen.—First two segments bright rufous brown, the second 
blackish towards the sides. Remaining segment mainly black, 
with a distinct, moderately wide pale yellow posterior border; the 
segments being a little reddish at the base, in the middle. Belly 
reddish brown, the black colour of the dorsum extended over the 
sides. 
Legs.—Pale yellowish brown, microscopically pubescent. All 
coxae with several strong bristles at tip. Femora bare of bristles, 
hind pair black at tip. Fore tibiae with a single bristle in front, 
just before the middle, and a row of minute ones in front, towards 
the tip. Middle tibiae with a row in front of minute ones, and 
another similar row on outer side, in addition to two strong 
divaricate ones near the base on the outer side, and a few at tip. 
Hind tibiae with three less strong bristles on outer side, and two 
or three near tip. Tarsi minutely bristly, rather darker. 
Wings.—Pale yellow, costal bristles, short, closely set, in two 
divaricate rows as far as the end of the 3rd longitudinal vein 
which attains the middle of the wing and is narrowly forked, the 
bifurcation somewhat elongated; 1st longitudinal with a sharp 
bend upwards at half its length, terminating beyond three-fourths 
of the costal cell. Of the discal veins the first 3 are only slightly 
sinuous, the first two being nearly parallel, slightly diverging 
towards the ends, but converging again at tips; 4th rather more
