" This genus differs from Erionota and Oangara in having the upper discocellular nervule of 
the anterior -wings longer than the lower ; the base of the second median nervule of tho 
anterior wings is also not more than twice as far apart from lower as from upper median 
nervule." (Distant, I. c.) 
" Antennae 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 ; discoeellulars 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 ; discoeellulars and vein 5 faint ; veins 2, 3, and 4 all close together ; 
vein 3 almost ecjuidistant from 2 and 4 ; vein 2 more than twice as far from base of wing as 
from end of cell. Hind tibiae with two pairs of spurs, the upper pair short.

Hidari grandis. (Plate XXXIX. fig. 13, c^ .) 
Plesioneura grandis, Leech, Eutomologist, xxiii. p. 47 (1890J. 
Ma]e. 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 
suffused 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, cS 55 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.

" 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 ; veiu 5 equidistant from 4 and (i ; 
upper discocellular minute, middle and lower discoeellulars subequal, almost erect ; vein 3
