LAMB—DIPTERA: HETERONEURIDA, ORTALIDA, TRYPETIDA, SEPSIDH, ETC. 315 
Front view (Plate 19, fig. 4) :—antenne well separate at base, face orange in that 
place, eye-margins well marked, densely pollinated: upper lip shining greenish-black, 
as is the protuberant clypeus. Side view (Plate 19, fig. 5) :—face deeply excavate, lower 
edge of broad lower eye-margins with a row of bristles: the bristly hind jowls and 
the back of head all grey pollinated. The bristly tongue is retracted in the specimen, 
but it can be seen that the palpi are orange: there is a hind lobe to the tongue which 
is chitinised like the clypeus and is also greenish-black. 
The antenne are darkish orange, the second joint singly spined above, the almost 
bare flagellum of the arista alone being blackish. 
Thorax. Somewhat shining greenish-black with regular rows of fine hairs. The 
pleura are shining bluish-black, very slightly scrobiculate. The specimens are rather 
damaged, but the following bristles can be made out: hind d. ¢., hum., n. p., 2 s. a., p. a. 
Scutellum bare, subtriangular, coloured as thorax; divergent terminal and smaller 
basal bristles. 
Wings, Fig. 9, slightly suffused, with brown veins, darkened at tip, on stigma 
and below it to 2nd vein. Halters, knobs yellow, stalks darkened at the base. Legs 
entirely dark reddish-black except about the distal third of the femora and the knees 
which are orange, the under surface of the femora (when legs are stretched horizontally) 
shows signs of a purplish chitinisation. The legs are covered with small spines, and on the 
front femora beneath the spines are longer and form a regular row. All the femora (in 
the dried specimens) are remarkably flattened sideways. There is a strong black spine 
at the end of the middle tibia. 
Abdomen and metasternum coloured as the thorax, the 2nd and 3rd segments 
making up most of the length, the surface with sparsely scattered black bristles.
