NTMPHALID^. 
This species seems to be fairly 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, Meigen, Eur. Schmett. i. p. 97 (1829). 
Arye, Westwood, Gen. Diurn. Lep. p. 383 (1851). 
"Body elongate, moderately hairy. Wings large, slightly scalloped ; white, with black markings. 
" Head rather small, moderately hairy. 
" Eijes prominent, naked. 
" Labial palpi rather short, obliquely porrected, scarcely reaching above the level of the middle 
of the eyes, extending to about two thirds of the length of the head, remotel)' apart, the 
first and second joints bat 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. 
Antenme 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 carinated 
beneath on the inner edge. 
" TuouAX of moderate size, clothed with woolly hairs, especially in front. AVings large, rounded, 
and with the outer margin more or less scalloped. 
" Fore ivitii/s with the costal margin moderately arched. The apical margin convex, more than 
two tliirds 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 tho 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 ; 
tho middle one emitting a short spur backwards into the discoidal cell, near its junction 
with the outer one. Tho median and submedian veins are not dilated at the base. 
" J/ind wirir/8 large, nearly rounded. Anal margin not incised near its extremity. Costal 
margin much arched. Costal vein not extending far beyond the middle of tho costa. 
Discoidal cell much shorter than in Chionobas. Tho u])pcr discocollnlar arising at a short 
dintMnco from tlie base of the branch of the postcostal vein, and forming the slightly 
curved base of the discoidal vein ; whilst tho lower discocellular is longer than tho upper, 
and united to the tliird brancli of tlio median vein much nearer to its origin than tho 
space between tho rust and scctmd branches of tiio latter.
