Dipterous Insect from Kashmir. 383 
First flagellar segment cylindrical, about as long as the two 
scapal segments together, one or two short bristles on the 
inner or anterior surface near the tip. Second and third 
flagellar segments cylindrical, together slightly shorter than 
the first, each with a blunt pale prominence on the inner 
(anterior) side beyond the middle, the prominences bearing 
several short pale bristles ; there are also a very few short 
and fine hairs on the dorsal surface. ‘Terminal joint bare 
except for a few fine hairs near the base, tapering very 
slightly to just before the tip, which is slightly but distinctly 
swollen. 
Thorax absolutely bare, the integument dull black. 
Pronotum not traceable. Mesonotum very convex and 
produced forwards over the head; rounded but rather 
narrow in front, very broad behind. No definite suture 
separating the preescutum and scutum, but deep and well- 
marked divisions between the scutum, scutellum, and post- 
notum. Area in front of scutellum flat. Scutellum 
extending to almost the full breadth of the mesonotum, and 
of even width throughout, its posterior margin slightly 
rounded. Postnotum large, convex. Owing partly to the 
intense blackness, it is difficult to make out the divisions of 
the pleurz in the whole specimen, and the thorax of the 
mounted one is damaged. There is a rather large mem- 
branous area below and in front of the wing-root. The 
mesosternum is almost flat. The mounted specimen shows 
that the prothoracic and metathoracic spiracles are both 
large, and are each supplied with several tracheal trunks, 
uniting just inside the spiracular opening. 
Abdomen broad at the base, and tapering considerably 
towards the tip, rather feebly chitinised, covered with a fine 
microscopic pubescence and with a few scattered transparent 
punctures on the tergites. First two segments very much 
reduced, without definite tergal plates, but quite distinguish- 
able in the formalin specimen. Third segment as long as 
the first two together, but still small. Fourth to seventh 
all rather large, about equal in length, but decreasing in 
breadth. Eighth reduced to a mere ring, but more strongly 
chitinised than the preceding. There is absolutely no trace 
of spiracles in the abdomen—a very unusual condition 
for an adult insect, as it appears to me. Possibly the 
spiracles may be represented by groups of two or three 
minute bristles, which occur in the places where the spiracles 
would be expected. Tracheze, reaching back from the thorax, 
are confined to the basal half of the abdomen. Hypopygium 
of very simple structure, not rotated, turned upwards.
