382 Mr. F. W. Edwards on a remarkable 
Cyclorrhaphous families. The reduction of the basal seg- 
ments of the abdomen might also seem to point in the same 
direction. However, the structure of the hypopygium is of 
a distinctly Nematocerous type, and not at all dissimilar 
to that of the Blepharoceride. This organ almost certainly 
provides the most reliable evidence of relationship. The 
connection with the Blepharoceride may therefore be 
expected to be coufirmed when the larve and pupe are 
discovered. It may be noted that some rather remarkable 
unidentified Blepharocerid larvee from Kashmir have been 
described by Agharkar (Rec. Ind. Mus. x. 1914). 
Unfortunately, nothing was noted by the collector con- 
cerning the habits of the flies, and only the male sex was 
obtained. 
Deuterophlebia mirabilis, sp. n. 
Colour deep dull black ; abdomen less intense than the 
thorax ; wings greyish, slightly opaque. 
Head. The head is rather small, and placed so far back 
under the projecting thorax that only small portions of the 
eyes are visible in adorsal view. In shape the head is about 
one-third broader than long, and very thin and flat, its 
diameter from front to back being less than that of the 
rather small eyes. The front of the clypeus has a trilobed 
appearance, the middle lobe bearing a number of short 
bristles. The distance between the eyes is about half the 
breadth of the whole head. The occipital foramen is very 
large, occupying about two-thirds of the breadth of the head, 
and there is no distinct neck. The eyes are subspherical, 
without any trace of division into two parts, or of differenti- 
ation in the size of the facets. There is absolutely no trace 
of ocelli or of mouth-parts, but the mouth is present as a small 
oval opening on the under side of the head, leading directly 
into a chitinised internal tube. On each side of the mouth- 
opening is a small tubular pocket with strongly chitinised 
walls, near the opening of which is a small bristle. The 
antenne consist of a two-segmented scape and a four- 
segmented flagellum ; the first five segments are together 
not much longer than the breadth of the head, but the 
remaining segment is fully three times as long as the whole 
body ; the scapal segments are transversely placed, the base 
of the flagellum at first continuing in the same direction, 
and then curving forwards. First scapal segment about 
twice as long as the second, and somewhat broader, second 
cup-shaped, somewhat. oblique, and about as long as broad.
