130 Records of the Indian Museum. [Vor Soy 
Not represented in the Museum collection. 
A green (or blue) and black species readily distinguished from 
the other similarly coloured Indian species (J. senegalensis) by the 
pterostigma of the fore-wing which is much narrower in front than 
behind and has its hinder margin very strongly convex. In this 
respect it resembles J. aurora. 
The female remains unknown. Length of abdomen o 24 mm., 
hind-wing 15 mm. Recorded from Quetta (Morton) and Kumaon 
(Laidlaw). 
Range probably restricted to the foot hills of the west and 
central Himalaya. 
The type male of J. gangetica is in the British Museum.

The female has not been described (see note under J. znarmata). 
Pterostigma dull gray. 
Head, prothorax and thorax as in the male, but with a duller 
ground colour. 
Abdomen rather stouter than in the male. Ground colour pale 
yellowish-brown, with a metallic black line on the dorsum of each 
of the segments, this line is moderately broad, pointed in front, 
and widening a little at the apex of each segment. 
Range: Bengal, Assam, and doubtfully Kashmir (see note 
under J. inarmata, Calvert). 
Ischnura inarmata, Calvert. 
Ischnurva inarmata, Calvert, Proc. Acad. Nat. Sct. Philadelphia, 18098, 
pp. 147-148, text-figs. 1, 2. 
2¢07,12 ?, Kashmir, 1915 (H. T. Pease). 
The female appears to have been taken at the same time and 
place with the males, and is in all probability con-specific. 
It seems also to belong to the same species as 3 @ @ recorded 
by Morton from Kashmir (Tvans. Ent.-Soc. London, 1907, p. 307). 
' These specimens were however regarded by him as being pos- 
sibly examples of J. rufostigma, Selys. 
Against this view is the fact that the undoubted examples of 
females of I. rvufostigma described in this paper are quite different 
in their colour characters, and also the probability that J. rufos- 
tigma has a more easterly distribution. 
On the other hand Calvert describes a female specimen regard- 
ed by him as the female of J. inarmata, which also is quite distinct 
in colouring from the specimen before me, whilst it does not agree 
with Morton’s specimens; it may be added that his account of the
