Subfamily AGRIONINAE, Selys. 
(= Coenagrioninae, Kirby). 
Genus Ischnura, Charp. 
Represented in the Indian Empire so far as is known by six 
species ; one of these is possibly to be referred to a distinct genus 
when better known. Two species are of a wide distribution, the 
remainder probably have a restricted habitat. 
The genus itself is a dominant member of the Agrionine group, 
and the Indian area therefore shows a high percentage of endemic 
species. Ischnura is one of the genera which appears to be poorly 
represented in equatorial regions, having a richer representation 
in tropical and especially N. temperate countries.

The isochromatic females were all taken in Caicutta on July 
27th, 1914. They can be distinguished from the males only by 
careful scrutiny. Fighteen males were taken with them.

a group of closely allied species whose distribution is well-nigh 
cosmopolitan.
