58 NYMPHALID^. 
This species seems to be faii'ly common in the neighbourhood of Chang- 
yang. 
I have an example from Wa-ssu-kow, and as this exhibits considerable 
deviation from the type, which does not appear to occur in Western China, I 
describe it as 
Var. OCCidentalis, var. nov. All the wings have the outer third blackish, with the typical white 
coloration more ochreous, and on this portion of the primaries represented by spots ; the neura- 
tion is also broadly bordered with blackish. 
Genus MELANARGIA. 
Melanargia, Mcigen, Eur. Schmett. i. p. 97 (1829). 
Arye, Westwood, Gen. Diurn. Lep. p. 383 (1851). 
"BoDT elongate, moderately hairy. 'V^'iugs large, slightly scalloped ; white, with black markings. 
" Head rather small, moderately hairy. 
" Eyes prominent, naked. 
" Lahial palpi rather short, obliquely porreoted, scarcely reaching above the level of the middle 
of the eyes, extending to about two thirds of the length of the head, remotely apart, the 
first and second joints but slightly clothed with long, erect, hairy bristles ; the terminal 
joint one third of the length of the preceding, scarcely hairy, slender, acute, and naked at 
the tip. 
'■'■ AntCHiue not half the length of the fore wings, slender, with the joints not very distinct ; 
terminated by a long and very gradually formed rather slender club, finely cariuated 
beneath on the inner edge. 
" Tnoiux of moderate size, clothed with woolly hairs, especially in front. Wings large, rounded, 
and with the outer margin more or less scalloped. 
" Fore wings with the costal margin moderately arched. The apical margin convex, more than 
two thirds of the length of the costa. Inner margin longer than the apical one. Costal 
vein moderately swollen at the base. Veins arranged as in Chionobas, except that the 
discoidal cell of the fore wings does not extend quite to the middle of the wing, which is 
marked towards the costa with a large black patch, traversed by the discocellular veins ; 
the upper of which is very short and almost obsolete ; the middle and outer one much 
longer, forming a nearly continuous curved line, varying, however, in its precise direction ; 
the middle one emitting a short spur backwards into the discoidal cell, near its junction 
with the outer one. The median and submedian veins are not dilated at the base. 
" Bind wings large, nearly rounded. Anal margin not incised near its extremity. Costal 
margin much arched. Costal vein not extending far beyond the middle of the costa. 
Discoidal cell much shorter than in Chionobas. The upper discocellular arising at a short 
distance from the base of the branch of the postcostal vein, and forming the slightly 
curved base of the discoidal vein ; whilst the lower discocellular is longer than the upper, 
and united to the third branch of the median vein much nearer to its origin than the 
space between the first and second branches of the latter.
