shining through. $ like the ^, the wings somewhat broader and more obtuse. In some specimens of both 

 sexes the spots at the costal margin of the hindwing are absent or very indistinct; in one of the specimens 

 there appears in the anal angle of the hindwing beneath a large spot shaped like a C, which is distally edged 

 with a black line and above which there is a blackish spot in the posterior median interspace (after Leech). 

 West China, June-August; Central-China, May- July. 



2. Genus: ]>ilipa Moore. 



The species of this genus resemble in aspect certain forms of Apatura (fiilva), from wliich Dilipa differs 

 mainly in the cell of the fore- and hindwing being closed by a distinct posterior discocellular. Further distinc- 

 tions: eyes hairy; the 2. subcostal of the forewing originates at a considerable distance beyond the apex of 

 the cell; precostal of the hindwing forked. Palpi and antennae as in Apatura. Larva slug-like, with 4 short 

 dorsal projections; head with 2 horns. Pupa suspended, carinate, head with 2 processes. 



D. fenestra Leech (^ = Apatura chrysus Oberth.) (51c) is a singular species, red-brown being its prevailing fenestra. 

 ground-colour. In the (J the forewing dusted witli blackish in the basal area, there being further a broad black 

 oblique band from the costal margin to the second median branch, behind the band a round spot as in the 

 $, at the hinder angle an elongate spot, anteriorly 2 transparent subapical spots; the distal margin edged with 

 black. Hindwing also margined with black distally, with a median band composed of 6 black spots, the basal 

 and hindmarginal areas grey dusted with black. Underside as in $, ground-colour of the forewing more yellow. 

 West China: Omei-shan, Lufang; in July, very rare. — The second, but essentially different, known species 

 of this genus, D. morgiana Westw., inhabits the mountains of North India and touches the Palaearctic territory 

 only in the North-West (Kashmir). — Nothing is known of the habits. 



3. Genus: Sephisa Moore. 



In the general habitus likewise similar to certain species of Apatura (laverna): eyes naked; antennae 

 long, with distinct club; palpi erect, densely covered with scales; thorax robust; abdomen relatively small. 

 Distal margin of forewing obtusely angulate below the apex; costal vein terminating beyond the centre of the 

 costal margin, subcostal 4-branched, 3 branches standing beyond the cell. The cell open in both wings. Precostal 

 of hindwing simple, curved outwards. Larva limaciform, with granulated lobes, the head with horns, the 

 apex of the body with 2 processes. 



S. dichroa Koll. (."jBa). Upperside reddish brown, with black markings, the forewing beneath similar, in didiroa. 

 places dusted",with whitish or whitish blue, hindwing almost entirely whitish, with some yellow smears, a row of 

 blackish spots in the distal area and a submarginal undulate line. ? somewhat larger, the wings broader, on the upper- 

 side not essentially different from <^, beneath the forewing more abundantly whitish, on the hindwing the blackish 

 spots developed to a lunate band, on the whole duller in tint. — Larva green, slug-like, with 2 pointed anal 

 processes, skin rugate and shagreened, the 8. and 11. segments each with 2 small, granulated, lobiform pro- 

 jections, the anterior segments with 2 yellowish dorsal lines, the posterior segments with oblique stripes, also 

 yellowish, between the dorsal protuberances a red spot; the head with 2 ochre-yellow branched horns. It feeds 

 on a species of oak (Quercus incana); rests on a silk-pad on the upperside of a leaf along the centre, the head 

 being directed towards the stalk with the frons downwards, the horns therefore projecting foi-ward. Pupation 

 in May. The butterfly appears early in June; it is fond of ripe fruit, and is met with in open woods resting 

 on the branches of tall shrubs, quickly darting away and returning to the same spot (Moore, Lang). West

 and subapical spots of the forewing being brown instead of white. Corea; China: Chang- Yang, Omei-shan.

 distinguished by the reddish brown ground-colour of the forewing being reduced to a few spots situated in the 

 basal area; moreover, the oblique macvdar band in the distal area is pure white; the hindwing, besides a black 

 cell-spot, has no essential differences from dichroa. It is doubtful, if chaiidra is specifically distinct, and it is 

 described here for the sake of completeness, apparently not extending into the Palaearctic Begion. The $ 

 appears in several forms, which will be dealt with in the volume on the Exotics; Nepal and Sikkim are the 

 true home of the form, which is distributed as far eastwards as Upper Siam.
