Body rather strongly glossy. Anterior border of hindwing inclusive of cell (apart from a small spot) black, 

 a distinct black bar on the cross-veins of forewing; cell of forewing truncate, the lower angle almost acute,

 clothed with large scales of which the apex is rounded; forewing only very faintly transparent, with 

 distinct, pale blue sheen, distal margin feebly rounded, 1. median from the obtuse angle of cell, midwaj' 

 between the 3. radial and 2. median; in hindwing 1. median rather distant from cell-angle, also midway 

 between 3. radial and 2. median. Clasper broad, with simple ventral margin, there being a spiniferous 

 hump on inner side at base. — Japan. 



odiracea. I. ochracca Li'i'cli (3e). Bodj' and antenna without metallic gloss. Abdomen grey-yellow, clay-

transvcna. I. transvena sj)ec. nov. (3d). Smoky black; wings partly transparent between the veins, black on 



the veins and at the edges, the forewing bearing a sliort subapical band of the same colour; a streak from

Pil. cybele Leerli (3e) cf. Antenna very strongly glossy, shortly pectinate, the distal segments 

 dentate. Forewing in sha})e like that of Illiheris mienni:< , distal margin somewhat longer; apex of cell 

 rounded, 4. and 5. subcostals from a point, 2. and 3. radials stalked (individual character? the 2. radial 

 absent from the right wing), both medians distant from cell-angle, the 2. nearer the base than in /. xhiemift. 

 Distal margin of hindwing not emarginate, 1. radial absent, cross-vein feebl}- curved, 2. and 3. radials long- 

 stalked in the right wing, from a point in the left, but in this wing the 3. radial distally not developed. 

 Clasper broad. — Gensan, in June, one cf collected by Leech. 



Pll. translucida /'onj. (3f). Similar to Il/ibcris tcnuh, larger, veins and wing-margins broader black, 

 the lihick stripe along hindmargin of forewing dilated distally of middle, 4. and 5. subcostals stalked. — 

 West China, in June. 



Pll. dirce Leech (3f). Apex of forewing broadly black, like the black hindmargin with a purple- 

 blue sheen in side-view. — North China, (^orea. 



Ph. nigrigemma Walk. {^= cyanecula //. Srh.) (3g). Antenna of a" and ? long -pectinate, very 

 strongly glossy. ? with yellow anal woolly tuft; clasper of cf with a long hook the tip of which is curved
