male of A. loha and two of A. padma, from Huang-mu-chang, agree in 
having this subcostal spot. In the example of A. loha the spot is not so 
well defined as it usually is in this species, and one of the A. iKidma corre- 
sponds exactly with it ; the other specimen of A. padma has the spot almost 
as well developed as in typical A. loha. 
These two species may be separated at a glance by the striation of the cell 
on the under surface of primaries, which in Chinese specimens of A. padma 
is coarse and fills the entire cell in both sexes, whereas in A. loha the stria- 
tion is much finer and in some of the males altogether absent. 
Generally common and widely distributed throughout Western China. 
In his paper on the " Lepidoptera of Sikkim," Mr. Elwes (/. c), referring to 
this species, says : — " I took it only on the Singalelah Range, which bounds 
Sikkim on the west between Tonglo and Phallut, at elevations of from 10,000 
to 12,500 feet, in July; but it was most abundant on the grassy ridge beyond 
Sundukpho above the pine-forest, where it flies strongly above the trees, 
resting on their* trunks, and settling on flower-heads in the open parts and 
on the edge of the forest." 
Aulocera merlina. 
Satyrus merlina, Oberthur, Etud. d'Entom. xiii. p. 40, pi. x. fig. 105 (1890). 
Male. Black, tlnfjcd with bronzy brown in certain lights. Primaries have a faint pale streak in the 
discoidal coll, and are traversed by a broad white macular band ; the second, fourth, and fifth 
spots of this band are each transversely divided by the interposition of a roundish spot, which 
is rather darker than the ground in colour. Secondaries have a broad white central band 
intersected by the nervulcs, its inner edge angulated. Fringes white, broadly chequered 
with the ground-colour at the extremities of the nervules. Under surface of primaries shining 
fuscous grey-brown ; a broad white streak on the cell; macular band as above, and there are 
some pale greyish markings along the apical portions of the costal and outer margins; second- 
aries blackish, with the central band rather narrower than above, and some pale greyish 
markings on the outer third of the Aving, and also along the abdominal margin. 
Female. Similar to the male, but the streak in the cell of primaries above is more clearly defined, 
and the transverse bands on all the wings are l)roader. On tlie under surface the markings are 
also similar, but the Ijasal area of secondaries is also marked with greyish. 
Expanse, c? 75 millim., 5 75-80 millim. 
Widely distributed and not uncommon in Western China. It is on the 
wing from .June to August.
