Cj'clorrliaplions families. Tlie reduction of the basal scg- 

 nienrs ol' the abdomen might also seem to point in the same 

 direction. However, the structure oF the hypopygium is of 

 a distinctly Ncmatocerons type, and not at all dissimilar 

 to that of the Blepharoccridai. This organ almost certainly 

 provides the most reliable evidence of relationship. The 

 connection with the Hlepharoccridjie may therefore be 

 expected to be confirmed when the larvie and pupaj are 

 discovered. It may be noted that some rather remarkable 

 unidentified Hlcpharocerid larva? from Kashmir have been 

 described by Agluirkar (Rec. Ind. Mus. x. 1914). 



Unfortunately, nothing was noted by the collector con- 

 cerning the liabits of the flies, and only tiie male sex was 

 obtained. 



Deuterophlebia mirabil'is, 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 tliat only small portions of the 

 eyes are visil)le in a dorsal 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 trilobcd 

 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 chitiuised internal tube. On each side of the mouth- 

 opening is a small tubular pocket with strongly chitiuised 

 walls, near the opening of which is a small bristle. The 

 anteymoi consist of a two-segmented scape and a four- 

 segmented Hagellum ; the first five segments arc together 

 not mucli 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.
