submarginal spots of the fore wings generally merge, on the hinclwings they are faintly indicated. The underside 
of the hindwings and the apex of the fore wings are buttercup yellow. In the <§<$ the ground colour of the wings 
is pure white, in the $$ yellowish white. Thibet. 
M. joubini Oberth. (7 a). The markings are similarly placed to oberthun Leech (Vol 1, Plate 18 c) and jouhini. 
hastata Oberth., it is one of the largest Whites. Ground colour of the upperside is white with a faint tinge 
of greenish-yellow. In the distal part of the disc there is a dark brownish mark in the shape of a horse-shoe, 
suffused inwards, all the veins of the forewings and hindwings are edged with brownish having spoon-handle 
shape. The costal nervure is dusted with bluish-grey towards the base, with brownish at the distal end as also 
is the inner margin. Between veins 1 and 2 of the forewings there is a brownish black streak. The underside 
of the forewings is greenish-white, the apex from the disc yellowish, veins 1—4 are widely edged with brownish. 
At the end of the disc and in the yellow apex there is a large dark brown spot deeply incurved inwards. Hindwings 
pale yellow with orange coloured basal spot, all veins more or less edged brownish. Tseku in Szechuan. 
M. leucodice Ev. (Vol. 1, Plate 19 a). ab. nigroinspersa Vrty. is a very adumbrated form from Mount leucodice. 
Hissar. The black marginal markings on the upperside of the forewings fill out the entire apical area, the ni( J roin - 
underside is richly powdered with black. — In Semirjetschensk in north Turkestan a large very pale race

M. genestieri Oberth. (Vol. 9, p. 139, Plate 57 a). Head, antennae, thorax and legs are black, sides of genestieri.y 
abdomen grey-white. The ground colour of the wings is white with a faint greenish tinge on the upper and ^ 
undersides. At the base on the underside of the hindwings there is a large yellow or orange-yellow spot. The 
veins are edged with black-brown which frequently so expands that a wide marginal band is created, this 
expansion occurs chiefly in the 2 and show's then a pale half transparent brown. On the underside the marking 
of the veins is narrower and does not extend towards the base. Lu-tse-kiang, Szechuan. 
M. delavayi Oberth. (Vol. 1, Plate 18 a). According to Verity a very small dwarf race occurs constantly delavayi. 
at Ta-tsien-lu (Szechuan). It has a wing expanse of scarcely 60 mm = nana Vrty. nana. 
M. acraea Oberth. (Vol. 1, Plate 18 d). Draeseke describes a form of the 3 from Wasseku in Szechuan aaraea. 
as funkei, the black markings are so strongly reduced that even the dark disco-cellular spot of the forewings junker. 
is absent and only a wide dark brown band remains at the margin. 
M. larraldei Oberth. (Vol. 1, p. 43, Plate 18 d and Vol. 9, p. 139). In Tseku and probably in all localities larraldei. 
the pretty ab. albivena Oberth. occurs among the name type form. The black markings are more extensive on albivena. 
the upper and undersides than in typical specimens and from this dark ground the white scaled veins contrast 
sharply. 
M. monbeighi Oberth. (7 a). Oberthur has received from Siao-Ouisi near Ta-tsien-lu only <$<$: these monbeighi. 
are very similar to melania Oberth. (Vol. 1, p. 43), but the wings are more rounded and the margin of the hind¬ 
wings has elongated square white spots. The species occurs in paler and darker forms, viz: in regard to the 
expansion of the white markings. Perhaps it is the <$ of melania Oberth.

form by the very extensive expansion of the black markings to the submarginal band and the copious distribution me l an °~ _ ^ 
of black scales. In the Tsing-ling mountains a very pale race occurs tsinglingica Vrty., in which all black tsinglingica. 
markings have disappeared except for traces at the outer edge of the disc and a very faint indication of a 
submarginal band.
