Annandalia, gen. nov. 



Mandibles strongly dentate. Palpi with the terminal segment 

 lanceolate, attenuate to apex. Antennae short. Wings short and 

 broad, hairy. Subcosta and radius separate to the wing margin. 

 Costal space wide basally, with a basal recurrent vein. Two 

 subcosto-radial cross-veins, one basal and one near the middle of 

 the wing. One series of gradate veins in the fore wing situate 

 just beyond the middle of the wing, wanting in the hind wing, 

 both wings with a very wide area of dichotomous forks. 



Type, the following species : — 



Annandalia curta, sp. nov. 



(PI. xxi, figs. 2 — 4.) 



Two specimens from Calcutta, collected by Dr. Annandale on the 

 3rd August, 1906. [Single individuals of this species are not 

 uncommonly found in Calcutta seated at night round lamps 

 on the whitew^ashed walls of houses. They are very sluggish.

Length of body 4 mm. Length to wing tips 5 mm. Antennae 

 2 mm. Expanse of wings 9 mm. Fore wings, length 4 mm., width 

 2 mm. ; hind wings, length 3 mm., width i'5 mm. Fore wings oblong, 

 obtusely rounded at both ends, and oblique ; hind wings obovate 

 obtuse at outer end. Membrane of wings hyaline, strongly marked 

 with brown in two shades, the colour being laid on in transverse 

 concentric lines around the wing base as a centre. The veins are 

 alternately yellow and brown, the brown occurring where the 

 concentric lines of dark colour cross the veins. There are three 

 darker areas in the fore wing, a blackish one on the base of the 

 wing extending outwards to the base of the radial sector, upon 

 which is a black tri-radiate spot ; there is a second dark area, a 

 little paler, laid across the base of the second division of the radial 

 sector, and this is confluent at fore and hind margins of the wing 

 with a third darker area, which encircles the wing apex covering 

 the terminal forks of the veins. The hind wings are largely hya- 

 line, slightly infuscated on the costal area and on area of the 

 marginal forks. The hind wing is almost without cross-veins. 

 The anterior branch of the cubital vein is in the fore wing 

 dichotomously four times forked, and the median vein three times 

 forked. 



The general colour of the bod}^ is blackish brown. The head 

 is wholly blackish The antennae are dull yellowish, darker at 

 both ends. The antennae consist of about forty remarkably 

 uniform segments, each hardly longer than wide, only the two 

 basal and terminal segments markedly differentiated ; the basal one 

 being four times as long as the second segment, and likewise the 

 last segment about twice as long as the others. The labrum is 

 semicircular, and the palpi are black in colour and lance- acumiate 

 in form.
