122 JUURNAL, BOMBAY NATURLA HIST, SOCIETY, Vol. XXVIII, 
Abdomen tumid at the base, a little constricted at the 3rd segment and from 
thence of even width as far as the anal end, the 9th and 10th being slightly 
broadened. Cylindrical and smooth due to the absence of the supplementary 
ridges on the sides. Ground colour ochreous on the dorsum changing to oli- 
vaceous or greenish yellow on the sides and beneath. 1st segment brown on 
the dorsum, this colour extending out as a transverse median line and also 
along the apical margin. Space between the Ist and 2nd segments greenish 
yellow. The dorsum of the 2nd segment turquoise blue, its apex finely and base 
rather more broadly black or dark brown, its sides silvery white ; the dorsum 
of segments 3 to 7 irregularly and narrowly brownish black and with a small, 
lateral, diffuse brownish spot at the lower part of the apical half; on 8 and 9 
this spot extends basalwards and joins up with the black of dorsum which is 
much more extensive on these two segments, and thus encloses a large spot of 
the ground colour, on segment 8 there is also a smaller spot enclosed at the base ; 
10th segment has a single, large apical spot on each side, connected across the 
dorsum apically with each other. 
Anal superior appendages as long as the 9th and 10th segments taken together 
lanceolate, tapered to a fine point, strongly keeled, the keel raised into a robust, 
spinous process near the apex of the appendix, very prominent when viewed 
from the side, reddish brown. Inferior appendage not half the length of the 
superior, yellow stippled with black bordered laterally above with several, 
robust imbricated, black spines. 
Female very similar to the male but differing as follows :— 
The occiput instead of being concave behind, projects back slightly in the 
form of a fine lamina the edge of which curls slightly up. Above it is raised 
into a pyriform, shiny bosse, the broad, rounded end of which is sharply 
marked off from the laminated, posterior portion. 
The abdomen is more tumid, the 3rd segment not constricted but tapering 
gradually to the anal end ; the 2nd segment has only a small spot of turquoise 
blue on its anterior third ; the sides of the 3rd segment more broadly white ; 
the black markings less extensive on segments 3 to 7. 
The anal appendages more typically lanceolate and with a strong keel run- 
ning throughout their length and not raised in a tubercle or spine near the 
apex. Dentigerous plate very similar to that of Anax parthenope parthenope, 
rounded and subdenticulate. 
Hab.—Mesopotamia, Persia, North Africa, India throughout the plains and 
dry areas, more especially Sind, Gujerat, Rajputana and parts of the Deccan. 
This species is given to long migrant flights, often swarming in great numbers. 
I saw one such on the 20th November 1919 when at sea, some 40 miles off the 
Kathiawar Coast. All the specimens taken on board the ship were fresh, and 
some quite teneral. In Mesopotamia it breeds in irrigation canals and marshes, 
whilst in India I have found it breeding in small tanks. It is interesting to 
note that a close observer like De Selys when describing this species (under the 
name of Anax mediterraneus) quite overlooked the absence of the supplementary 
ridges on the abdomen which are so serviceable for identifying the inseer
