colour and pattern of the underside as a rule darker and heavier, the lines stronger, the light dots more 

 sharply defined. Length of forewing up to 48 mm. Central and West China, in July. 



B. Subfamily: Discophorinae. 



Butterflies with the body and wings strongly built, in size somewhat above the average of butterflies. 

 Pattern of the upperside consisting as a rule of light bands and spots of whitish, blue or brown tints on a dark 

 ground, there being usually 2 eye-spots on the underside of the hindwing. Head and body normal. Eyes large, 

 naked. Palpi but little ascending above the head, densely scaled and hairy. Antennae thin, slightly thickened towards 

 the end in the shape of a spindle, of about half the length of the forewing. Forelegs of the cfcf much reduced, 

 the tarsus having but one segment, while that of the ? is spinose and consists of 5 segments. Abdomen of cf 

 ventrally compressed to form a keel, this place not hairy, bearing on each side a dictinct velvety swelling for 

 friction.' Forewing with the cell closed, the middle discocellular absent, the subcostal 4- or 5-branched, only one 

 branch originating proximally to the cell-end, anastomosing with the costa and usually also with the second sub- 

 costal. Hindwing with open cell, the precostal simple, slightly curved basad. 



The Di^cophoyinae fly at day-time, but are fond of shady localities in the woods or bamboo-jungle, and do 

 not visit flowers, but suck at faeces and rotting matter. When thus busy they keep the wings closed, but are 

 very shy and flee for shelter into the bushes, settling there on the underside of leaves and returning to the aban- 

 doned place when their confidence is restored. The ??, which are rarer, seem to rest during the day, appearing 

 towards sunset. The flight of these insects is swift, energetic and jerky, but not continuous. 



The egg of the Discophorinae is globular, with smooth surface. The larvae feed on Palms, Sugarcane, 

 Bamboo and other grass-like Monocotyledons. They are cylindrical, finely pubescent, with two short anal processes; 

 head without horns. Pupa suspended, boat-shaped, head-piece with two projections. 



The separation of this subfamily as a classificatory unit from the Amatlni.'iiinae was carried out by Stichel 

 in 1902 based on natural distinguishing characters. Of the two genera which belong here, Discopliora and Enispe, 

 only the latter is represented in the Palaearctic Region, by one species. 



1. Genus: £iiispe Westw. 



Head large. Eye oval, convex, naked. Palpus long, very smootidy scaled and hairy, somewhat ascending 

 beyond the head. Antennae thin, slightly thickened towards the apex in spindle-form. Forewing a right-angled 

 triangle, the apex pointed, in the $ sometimes slightly produced; subcostal 4-branched, the 1. branch origin- 

 ating near the cell-end, shortly anastomosing with the costa, the 2. branch absent, the last 3 branches (here 

 subcostals 2 — 4) originate one from the other not far from the apex of wing; cell rather broad, init short, 

 the 2 anterior disco-cellulars absent. Hindwing pointed-ovate, costal margin somewhat arched, apex rounded, 

 anal angle produced, acute, precostal simple, nearly straight, its tip somewhat curved basad; cell narrow, 

 open. (J with a glossy friction-spot in the anterior portion of the hindmarginal area, bearing a small Ijrush or 

 patch of short bristles. 



(3nly one Palaearctic species. 



E. lunatus Leech (49b). Upperside red-brown, with blackish markings, wliich consist of narrow arc-like lunatus. 

 halfmoons near the distal margin. Underside pale brownish yellow, somewhat darker in the basal area; across 

 the cell of the forewing two brown angulate lines, across the centre of the wing a narrow brown transverse 

 band, distally the markings of the upperside feebly shining through. Hindwing with an elongate brownish spot 

 in the cell, then follows a dentate line extending from the costal margin to the submedian vein, and further 

 a narrow brown transverse band across the centre of the wing, the outer-marginal area with the markings of 

 the upperside feebly indicated and a row of small brown halfmoons, between which and the middle band there . 

 are two small black dots, the posterior one bearing a silvery white centre. ? larger; upperside ochreous, distally 

 paler, shading into a broad whitish costodistal area. Pattern as in S, hut heavier. Western China, East Tiliel. 

 — In both sexes there occurs a smaller form, enervata Stick. (49c), with the markings essentially reduced. Length enervata. 

 of forewing 35 mm in c?, upperside uniformly reddish yellow, only the indented distal marginal band, the sub- 

 marginal row of Innules, and the spot in the apexof the cell are developed of the normal markings, but are strongly 

 paled. Hindwing at the margin with a row of shadowy halfmoons and more proximally a row of four 

 blackish elongate spots. Underside almost uniformly chrome-yellow, the basal area somewhat darker, being 

 feebly reddish, the markings of tlie upperside slightly sinning tlircnigh. ? differing still more from the main 

 form^ almost like its S, i'l contradistinction to the sexual dimorpliism of the previous form; colour somewhat 

 paler, the. markings greyish black, underside yellow. West-China: Siao-lu, Ta-tsien-lu; East Tibet. Perhaps 

 dry-season form.
