space between the base of the wing and the lirst branch being proportionately shortened ; 
in others the base of this vein is swollen, and the space between the first and second 
branches as short as usual. SubmeJian vein simple, and curved at the base iu some 
species, which have a slit enclosing a tuft of hairs opposite the origin of the first branch 
of the median vein, but greatly swollen at the base in other species, which have not this 
slit, the tuft of hairs being placed in these on the upper surface of the hind wings. 
" Hind uinr/s with the costal vein extending about two thirds of the length of tho costa. Post- 
costal vein arising opposite the origin of the precostal; its branch arising at a considerable 
distance from its base. The discoccllular veins forming a nearly continuous rather obliquely 
transverse termination to the diseoidal cell ; uniting with tho median vein exactly at, 
or a little beyond, the origin of its third branch. The diseoidal cell in some species bears 
along its outer edge a tuft of long pale hairs : whilst in others it is more generally 
clothed with numerous shorter hairs. Outer margin slightly scalloped. 
" Fore legs of the male small. Femur clothed with scaly hairs, slender, as long as the tibia and 
tarsus, which are thickly clothed with short hairs. Fore leys of the female much longer, 
slender. Tibia rather shorter than the femur or tarsus, which latter is articulated ; the 
articulations armed with short spines beneath ; the tips destitute of ungues. 
" Four hind legs rather long and slender, scaly, destitute of hairs, and with only a few very 
small spines on the sides of the tibias beneath. Tho tarsi also almost destitute of spines, 
and thickly squamose ; the scales hiding the terminal ungues. 
" Abdomen slender." (Douhledai/, I. c.) 
The Asiatic species of Ilycahsis have been separated by Mr. F. Moore 
(Trans. Ent. Soc. Lond. 1880, pp. 155-177) into 23 distinct genera, but, 
as Marshall and de Niceville observe, since " the structural features common 
to both sexes, on which reliance is placed in separating the groups, vaiy in 
aspect in the sexes of the same species, it is clear that they can only be 
accepted as generic differences with reservation. The divisions, as usual, 
rest chietly on the structure of the male insect, and especially on the 
presence and position of the sexual scent-pouches or glands, and the tufts 
of hau- which usually accompany them, and so far as these features go 
the divisions are more satisfactory " (Butt. Ind. i. p. 103).

Male. "Allied to M.janardana. Wings above smoky brown ; outer border narrowly whity brown, 
with marginal and subraargiual black lines; primaries with a large ocellus on first median 
interspace, black, with white pupil and narrow yellow iris. Wings below sandy brown, 
mottled with grey, crossed by a central narrow externally difl'uscd lilacine streak ; outer 
border narrowly whity brown, with subraargiual and marginal dark brown lines : primaries 
with four ocelli, the second and tliird extremely small and sometimes obsolete, the first also
