Hab.—Mesopotamia, India throughout the Deccan, Rajputana and Sind. 
I have found it breeding in small tanks in Poona. Elsewhere it is found 
throughout the Mediterranean, and Asia Minor and the Near East.

A’schna, Van der Lind. 
Very similar to genus Anazx but generally smaller and with shorter abdomen. 
The latter has no supplementary ridges on the sides of segments 4 to 8 and is 
therefore smooth and cylindrical. 
The superior anal appendages are sublanceolate in the male and taper more 
rapidly than in Anax, in the female they are typically lanceolate. Inferior 
anal appendages subtriangular and with the lateral borders furnished with robust 
imbricated spines. (Selys aptly described this appendages as resembling the 
lower jaw of a python with its imbricated teeth.) 
Wings similar to genus Anaz.

Length of abdomen 45 to 48 mm, of hindwing 45 to 46 mm. 
Male—Head : eyes sage green above changing to yellow beneath ; labium 
bright yellow ; labrum and face greenish yellow ; frons bright yellow, its anterior 
border and front blackish brown, its base very narrowly black before the eyes 
and vesicle ; vesicle yellow with a blackish base; occiput greenish yellow, 
slightly concave behind and raised in a medial ridge in continuation of the 
opthalmic suture. Eyes behind black and marked with bright yellow.

Thorax pale ochreous brown or sage green on the dorsum, greenish yellow 
on the sides, the metepimeron sometimes a bluish green. No markings save 
for a fine black belt bordering the coxe. 
Legs black, base ef hind femora reddish brown, anterior femora bright yellow 
behind, and within, black in front. Hind femora with a row of closely-set, 
gradually lengthening, but short spines. 
Wings hyaline but with a diffuse saffronated spot in the hindwing very si- 
milar to that seen in gutiatus extending from the trigone to well beyond the 
node. Much smaller and often entirely absent in the male. In addition there 
is some slight saffronation of the bases of the wings, especially in the female ; 
membrane white, its anterior margin narrowly black throughout its length ; 
stigma 5 to 5:5 mm in length, bright ochreous margined posteriorly with dark 
brown ; reticulation black and yellow, the costa yellow as far as apex ; trigone
