Hidari, Distant, Rhop. Malay, pp. 392, 395 (188G) ; Watsou, Proc. Zool. Soc. Lond. 

 1893, p. 123. 



" This genus differs from Erionota and Ganr/ara in having the upper discocellular nervule of 

 the anterior wings longer than the lower ; the base of the second median nervule of the 

 anterior wings is also not more than twice as far apart from lower as from upper median 

 nervule." {Distant, 1. c.) 



" Antenna; long ; club robust, elongated, with a long terminal crook. Palpi : second joint very 

 densely scaled, third joint almost entirely concealed. Fore wing: outer margin longer than 

 inner margin ; cell less than two thirds the length of costa ; discocellulars inwardly oblique : 

 vein 5 from close to bottom of cell ; vein 3 well before end of cell ; vein 2 almost equidistant 

 from end of cell and base of wing. Hind wing slightly lobate, outer margin even ; vein 7 

 well before end of cell ; discocellulars and vein 5 faint ; veins 2, 3, and 4 all close together ; 

 vein 3 almost eijuidistant from 2 and 4 ; vein 2 more than twice as far from base of wing as 

 from end of cell. Hind tibite with two pairs of spurs, the upper pair short. 



" Type, irava, Moore. 



" Confined to the Oriental region." {Watson, I. c.) 



Hidari grandis. (Plate XXXIX. fig. 13, s .) 



Plesioneura grandis, Leech, Entomologist, xxiii. p. 47 (1890j. 



Male. Fuliginous brown, all the wings paler towards base. Primaries with a greyish apical patch 

 and three subhyaline spots, one in the discoidal cell, a larger one below and a little beyond 

 in the first median interspace, and a smaller one in the interspace above ; fringes pale grey, 

 becoming darker towards apex of primaries. Under surface of primaries greyish, costal half 

 sufi"used with fuliginous from the base to just beyond the subhyaline spots: secondaries 

 fuliginous brown, sprinkled with ochreous scales ; fringes as above. 



Female. Similar in colour to the male, but without the greyish apical patch on primaries ; the 

 subhyaline spots are larger, the two central ones are only separated by the median nerve. 



Expanse, S 5o millim., $ 68 millim. 



Occurs in Western China at Moupin, Wa-shan, Wa-ssu-kow, and Omei- 

 shan, and in Central China at Chang-yang and Ship-y-shan. It is found at 

 elevations up to 5000 feet in June and July. 



Genus ISMENE. 



Ismene, Swainson, Zool. 111. vol. i. pi. 16 (1820-21) ; Watson, Proc. Zool. Soc. Lond. 

 1893, p. 125. Type, OBdipodea, Swainson. 



" Antennae : club very robust, about twice as long as shaft, terminal portion tapering to a fine 

 point and curved into a crescent, never bent into a hook. Palpi as already characterized. 

 Fore wing : inner and outer margins subequal ; cell slightly more than half the length of 

 costa ; vein 12 reaching costa almost opposite end of cell ; vein 5 equidistant from 4 and 6 ; 

 upper discocellular minute, middle and lower discocellulars subequal, almost erect ; vein 3
