ArT. 21. DRAGONFLIES OF BURMA AND LOWER SIAM—LAIDLAW. 9 
wing except the median space and the anal area is tinged with 
bright orange-brown; a teneral female, however, has the wing apices 
colorless. The male is said to have the wings uniformly of a yellow 
hue. The supratriangular space is crossed by a single nerve. Ris 
regards Needham’s Dolaeschna elacatura as synonymous with the 
present species. 
JAGORIA VENATRIX Foerster and JAGORIA BUHRI Foerster. 
Two other species have been described by Foerster; venatriz from 
Buton, an island of the Celebes group, of about the same size as 
modighant. The male only is known; and bihri from north Borneo 
closely allied to poeciloptera, but a trifle larger. The pterostigma is 
said to have a length of 2.5 mm., and the wings of the female to be 
entirely bright brown. Both species are unknown to me. 
JAGORIA PRYERI Martin. 
Jagoria pryeri Martin, from Japan, has the supratriangular spaces 
uncrossed, the hinder wing of the male is 38 mm. long, and the 
pterostigma 3.5 mm. and the wings are described as being yellowish. 
The inferior anal appendage of the male, the only sex known, is 
relatively shorter and broader than in other species of the genus. 
JAGORIA, species.? 
Lastly, the female specimen from Darjiling has the supratriangular 
spaces uncrossed and the wings colorless. The length of the hinder 
wing is 38 mm. and of the pterostigma 3 mm. 
Genus LINAESCHNA Martin. 
The Bornean genus Linaeschna, known from a single male specimen 
described and figured by Martin is, I think, certainly a close ally of 
Jagoria, though whether it is to be regarded as more primitive or 
more specialized I am quite unable to say. 
Genus AUSTROAESCHNA de Selys. 
Otherwise confined to Australia this genus is represented by a 
species from Assam. I can not find any character of importance 
sufficient to separate it generically from the Australian species. This 
interesting creature, known as Austroaeschna intersedens Martin, 
belongs to a small group of Himalayan species which seem to have 
relationship to Australian forms rather than to nearer neighbors. 
Such are Lestes cyanea de Selys and Argiolestes melanothoraz de Selys. 
Another Aeschnine Planaeschna milnei (de Selys) from Formosa and 
Japan is regarded by Martin as an Austroaeschna; I have not seen 
an example, but venationally it certainly comes very near intersedens, 
and may well be congeneric with it. But for the present I think
