NYMPIIALID^. 
double line of the grouucl-colour. Outer margin of secondaries bluish grey, intersected by a 
wavy line of the ground-colour. A siibmarginal series of from five to seven ocelli, with white 
pupils and reddish-brown irides, of which the second, third, and seventh, counting from the 
anterior margin, are often very faint. Internal to the ocelli is a series of bluish-grey 
crescents. 
Head, thorax, and upper surface of abdomen black. Legs and under surface of abdomen dark 
chocolate. Antennae black, chequered with white beneath ; tip and underside of club deep 
orange. 
Expanse, c? 55-58 millim., $ 50-54 millim. 
Except that the narrower blue fascia on primaries of the female resembles 
the same character in Bicyclus iccius, HeAv., and that the general colour of 
the wings on upper surface is something like that of Mycalesis martins, Fabr., 
this insect is quite distinct from any knoAvn species, and appears to be 
without any close ally. 
Occurs in Central and Western China, but it is local and not very common. 
Genus MYCALESIS.

" Body slender, finely hairy. Wings rather large, plainly and uniformly coloured, those of the 
males generally with a tuft of hairs on the upper side. 
" Head rather small, with a small conical tuft of hairs in front 
" Eyes naked, prominent. 
" Antennce scarcely half the length of tlie fore wings, very slender ; joints scarcely distinct ; 
terminated by a long but very slender club . 
" Lahial pal jii porrccted obliquely ; the tip elevated rather above the level of the top of the eyes, 
and advanced in front rather farther than the length of the head, very slender ; the first 
and middle joints sparingly clothed beneath with long, porrect, delicate bristles ; the 
middle of the second joint is also clothed on the back with a tuft of short hairs ; terminal 
joint very slend(!r, acute at the tip, short, and scarcely setose. 
" TnoHAX rather small, rather compressed, and very convex. 
" Fore winr/8 with the costal margin strongly arched. Apex rounded. Apical margin varying 
from slightly convex to slightly concave, entire, about three fifths of the length of the 
costal. Inner margin about one fourth longer than tlio apical, rather dilated in the 
male. Costal vein strongly swollen at the base. Postcostal vein with the first and 
Hccond branches arising from the anterior extremity of the discoidal cell, which extends 
to the middle of the wing. Upper discocellular vein very minute ; middle one longer, 
curved, rather obliquely directed towards the base of the wing ; outer discocellular much 
longer, strongly arched, united with the third branch of the median vein at a short 
distance from its origin. In the species in which the base of the median vein is not 
Bwollen, the sjjace between its first and second bi'anches is much longer than usual, the
