about three times as far from find of cell as from base of wing. Hind wing slightly lobed at 
anal angle ; discocellulars faint, erect ; vein 5 present, but very faint ; vein 7 three times as 
far from 8 as from 6 ; vein 3 just before end of cell ; vein 2 almost twice as far from base of 
wing as from end of cell. Hind tibise with two pairs of spurs.

The above description refers to the male, which sex is very much the 
commonest. The female is rather larger than the male, and has the wings 
rounder ; the spots forming the central band are rather larger, especially that 
on the costa, which is usually qua,drate. 
Var. contractus, var. nov. (Plate XXXVIII. fig. 9, J .) Rather greyer in colour ; the spots 
forming the central fascia are narrower and differently shaped, those towards apex are often 
minute. 
This form appears constant, and has so far only been met with at Wa-ssu- 
kow and "\Va-shan in Western China, in which localities the type form does 
not seem to occur. 
I met with it commonly about fifteen miles from Gensan at the foot of the 
mountains ; Fixsen also records it from Corea. In Western China it occurs 
at Ni-tou, Moupin, Chow-pin-sa, Pu-tsu-fong, Wa-shan (var. contractus), and 
Wa-ssu-kow (var. contractus). I have also received it from Chang-yang and 
Kiukiang in Central China and from Ningpo.

Male. Closely allied to A. nepos, Oberthiir, but can be easily separated by the ground-colour, 
which is very dark shining brown, instead of being tinged with olive ; the wings are rounder, 
and the outer margins of secondaries are not so indented ; the position of the two apical spots 
is also different. The colouring of the under surface more nearly resembles that of A. ger- 
nianus, Gberth., but the apical spots of primaries and the position of the dark bands on 
secondaries at once distinguish it from that species.
