about three times as far from end 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 tibiae 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 quadrate. 



Var. contractus, var. nov. (Plate XXXVIII. fig. 9, .) 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 Wa-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 tlie 

 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. TiepoK, Obcrtliiir, but can be easily soparalcd by tlio ground-colour, 

 which is very dark shining brown, instead of being tinged witli olive ; Iho wings are rounder, 

 and th(! outer margins of secondaries are not so indented ; the position of the two apical spots 

 is also difFeront. The colouring of tho under surface more nearly resembles that of A. ger- 

 maniix, (Jbertii., but tlie a])ical spots of jjriniaries and the position of the dark bands on 

 HccondurieH at once dislinguisii it from that species.
