examples they are so broad that they give the outer half of the wings the 

 appearance of being black marked with white lanceolate streaks in the 

 nervular interspaces ; in other specimens the nervules of secondaries are not 

 bordered with black at all. Sometimes the transverse band is entirely absent 

 in the male. In several specimens of the female and a few examples of the 

 male the under surface of secondaries is yellow. 



The melanic specimen figured was taken at Chang-yang. 



Judging from the enormous number of specimens that T have received 

 M. largeteaiii would seem to be the most abundant member of the Pierinee 

 occurring in Central and Western China at moderate elevations. From 

 M. phryxe, Boisduval, it may be distinguished by the absence of the large 

 black spot at end of the cell of primaries, and by the different character of 

 the transverse band.

 xvi. p. 5, pi. i. fig. 2 (1892). 



Male. White. Primaries : costa bordered with black ; nervules edged on each side with black, 

 expanding towards the outer margin, which appears in cousequenco to be deeply bordered. 

 Secondaries black at outer angle and halfway along the costa; nervules bordered with 

 black, and there are streaks of the same colour in the interspaces, pointed towards outer 

 margin and bifurcated at their inner end. Under surface similar to above, but the streaks 

 in interspaces of secondaries are connected with the borders of nervules ; a deep yellow patch 

 at base of secondaries. 



Female. The black borders of nervules of primaries are not quite so broad as in the male, but 



otherwise there is no difference in the markings of the sexes. 

 Expanse, cJ 80 millim., $ 92 millim. 



In one specimen the whole of the primaries is black with the exception of 

 the discoidal cell, a broad patch from the base between the median nervure 

 and inner margin, intersected by the submedian and a curved series of five 

 oblong spots beyond the middle of the wing.

Allied to M. acrcca, Oberth., but differing therefrom in tlie character of 

 the marginal borders.
