MYCALESIS.

space between the base of the wing and the Hrst 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. Submedian vein simple, and curved at the base in 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 ivinc/s with the costal vein extending about two thirds of the length of the costa. Post- 
costal vein arising opposite the origin of the precostal ; its branch arising at a considerable 
distance from its base. The discocellular veins forming a nearly continuous rather obliquely 
transverse termination to the diseoidal cell ; uniting with the 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 Jegs 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 liind legs rather long and slender, scaly, destitute of hairs, and with only a few very 
small spines on the sides of the tibiae beneath. The tarsi also almost destitute of spines, 
and thickly squamose ; the scales hiding the terminal ungues. 
" Abdomen slender." {Douhleday, I. c.) 
The Asiatic species of Mycalesis 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, vary 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 chiefly 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 wliity brown, 
with marginal and submargiual 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 diffused lilacine . s.treak ; outer 
border narrowly whity brown, with submargiual and marginal dark brown lines : primaries 
with four ocelli, the second and third extremely small and sometimes obsolete, tlie first also
