AULOCERA. 73 
Aulocera magica. (Plate XIII. tig. 4, d var.) 
Saiyrun muyica, Obertliiir, Etud. d'Eutom. xi. p. 24j pi. iv, fig. 21 (1886). 
Similar to A. merlirut, Oberthiir, but the spots forming the band of primaries are smaller, the sixth 
spot is completely divided longitudinally, and there are some indistinct pale streaks between 
it and the base of tho wing ; the band on secondaries is narrower and broken up into separate 
spots ; there is a white or whitish streak in tho discoidal cell of all the wings, but this is most 
conspicuous on tho secondaries. On the under surface this species is at once separated from 
A. merVuia by the distinct white discal streaks on aU tho wings. 
Expanse, S 75 millim., $ 80 millim. 
Apparently a very scarce species in Western China, as I have received but 
foiu' specimens. One of these is a female example, which is larger than the 
male, but does not differ in other respects ; another is a variety of the male, 
and of this I append a brief description : — 
Var. lativitta, var. nov. (Plate XIII. fig. 4.) The spots and streaks of the primaries are placed 
as in the type, but they are broader and distinctly white, and, in addition, there is a broad 
white streak along the inner margin extending from the base almost to the inner angle ; the 
basal two thirds of secondaries is white, intersected by the black venation, with a broad black 
bar between the costa and cell. — How-kow, July, 10,000 feet. 
Occurs at Ta-chien-lu, Wa-shan, and Chia-ting-fu in June and July; also at 
How-kow in Thibet. 
Aulocera sybillina. 
Satyrus sybillina, Oberthur, Etud. d'Eutom. xiii. p. 40, pi. x. fig. 106 (1890). 
Closely allied to A. hrahninus, Blanchard, and agrees with it in size, but in the male the white 
spots forming the transverse band of primaries are smaller, the sixth is always divided longi- 
tudinally, and the seventh is indistinct or altogether absent : the band of secondaries is rather 
curved and of uniform width from the middle to abdominal margin ; the upper portion of 
this band is sHghtly angulated towards costa and divided into spots. In the female the spots 
of the band on primaries are equal in size to those of the same sex of A. hrahmintis, but the 
sixth is divided as in tho male : the baud of secondaries is rather wider than in the male. 
On the under surface the primaries are fuliginous brown, with a white patch in the cell and 
some white mottling on the discal area ; the secondaries are black, with a subbasal patch of 
whit« on the costa and some white mottling on the outer area. 
Locally common in Western China during June and July.
