themselves into only two species. The coloured illustrations given in the Cat, 
Coll. Selys both for the Corduliince and the jEachnirue are exceedingly fallacious 
and to take one instance only, e.g., that of Hemicordulia asiatica, no one knowing 
the living insect would recognise it from the coloured illustration given in the 
work cited. It will be seen from the above descriptions that they will equally 
fit either Ingubris, acutifrons or orbifrons, not conforming to any entirelJ^ The 
descriptions have been made from Mr. H. Steven’s specimens and as an alterna- 
tive to giving them specific rank, I have placed them as C. orbifrons.

CephalcBSchna, Karsch, Ent. Nachr., xvii, No. 20, pp. 6-7, (1891); 
Laid., Rec. Ind. Mus., Vol. xxii, p. 78, (1921). 
Similar to the last genus in most respects but the neuration diffem somew'hat 
as also does the dentigerous plate of the female. 
Wings rather narrower, usually a little enfumed; stigma markedlj’ short, usually 
unbraced (or it would be better to say that the brace has shifted outwards and 
meets the stigma distal to its inner, posterior comer), 2 to 3 nervures converge 
on the posterior border of the stigma especially in the female ; trigones with 3 
cells in the forewdngs, usually 4 in the hindwing, other points as for Cephaloaschna. 
Dentigerous plate, of the female forking into two stout spines very similar to 
those seen in genus Gynacantha.

Male. Length of abdomen 46 mm., hindMing 40 mm. 
Head. Labium, labrum, epistome and frons olivaceous brown, the lips some- 
what more ochraceous ; occiput black, small, fringed with black hairs ; a fringe 
of longish, black hair also margins the front crest of the frons and is continued 
down on either side of the face ; ej^es broadly contiguous, olivaceous green. 
Prothorax brown margined finely with yellow.
