female is very incomplete, no mention is made of the thoracic 
colouring. 
Possibly the species has dimorphic females. In the absence 
of clearer evidence I propose to take this view. But of course /. 
vufostigzma may have dimorphic females. I tabulate these female 
forms below :— 
A. 1¢. Indian Museum. 
Head as in male J. inarmata, but ground colour orange 
instead of blue. 
Prothorax orange, with small paired black spots. 
Thorax orange. 
Abdomen, segments I—3 orange, apex of 3 marked 
with black, remaining segments metallic black above. 
B. 32 2. (Morton’s specimens). ‘‘ Like Pyrrhosoma tenellum 
(Villers), but thorax paler’’ (identical with A. ?). 
C. 322. (Calvert’sspecimens). Head coloured as in males. 
Dorsum of abdominal segments 1—1o0 dark metallic 
green, the articulations with narrow, yellow, trans- 
verse rings. 
This species is recorded from Kashmir only.

In bad condition. 
Range: India to Ceylon; Australia, not recorded from in- 
termediate territory so far as I know. 
Apparently not very common though widely distributed in 
India. 
Ischnura ? nursei, Morton. 
Ischnura?’ nurset, Morton, Trans. Ent. Soc. Lond., 1907, p. 306, 
pl. xxiv, figs. 4, 5, 6. 
A red and black species, unknown to me. The abdomen is 
described as being short and stout relative to that of other males 
of the genus; ‘‘ segments I—4 carmine, 5 lemon yellow, 6 yellowish 
in anterior half, remainder of abdomen metallic violet, posterior 
part of 10 and appendages reddish.’’ The species differs from 
other Ischnuras in the absence of post-ocular spots and is referred 
by Morton to this genus with doubt. The pterostigma of the fore 
wing is diamond-shaped, bright carmine inwardly, paler exter- 

Ischnura immsi, Laidlaw, The Entomologist, Aug. 1913, p. 236. Mr. 
Morton has pointed out to me (cz litt.) that this species is identical with Eual- 
lagma’ parvum, Selys. My name is therefore merely a synonym of Selys’ 
species to which I hope to refer in a later note.
