180 NYMPHALID^. 
angulated ferruginous central band, and a narrow band of the same colour precedes the 
fnliginous-grey outer marginal border ; venation black. 
Fi'malc. Similar to the male, but larger, and the spots are rather paler yellow. 
Expanse, d G6-76 millim., $ 84 millim. 
Appears to be common at Moupiii, Ta-chieu-lu, Wa-shan, Wa-ssu-kow, and 
Pu-tsii-fong in Western China, but I have only received two examples of the 
female ; this sex has not previously been referred to. The species is on the 
wing in June and July, and occurs at various altitudes up to nearly 10,000 
feet. The type was taken in the neighbourhood of Pekin. 
Limenitis cottini. 
Limenitis cottini, Obcrthiir, Etud. d^Entom. ix. p. 17, pi. ii. fig. 5 (1884). 
Male. Brownish black. Primaries with two infuscated whitish spots in the discoidal cell, with a 
smaller one below in the suhmedian interspace ; a broad central macular whitish band, and 
three white spots before the apex. Secondaries with one large whitish spot in the discoidal 
cell, and white macular band as on primaries, but broader. All the wings have indications 
of a submarginal series of whitish spots. Fringes of the ground-colour chequered with white. 
Under surface of primaries fuliginous, the costa and nervules on apical area and outer third 
of the wing bordered with ferruginous brown ; there is a short ferruginous streak between 
the discoidal spots, and one at the end of the cell ; spots and bands as ou the upper surface, 
but pure white : secondaries ferruginous brown, with a large white spot in the cell, and two 
smaller ones above it ; central band as on upper surface ; outer margin with a broad white 
band, traversed by aline of the ground-colour, and preceded b}' a narrower black band traveised 
by a white line ; both these bands are intersected by the ferruginous-brown nervules ; the 
abdominal margin is broadly white. 
Female. Except that the central markings are rather broader and sometimes purer white above, 
this sex, which has not been described hitherto, does not differ from the male in colour or 
ornamentation. 
Expanse, tS 56-62 millim., J 62-6G millim. 
On the upper surface the white spot in cell of secondaries varies in size ; 
in some male specimens it is much reduced, and in one or two examples entirely 
absent. The spots in cell of primaries are sometimes united, forming a 
notched discal streak on both surfaces of the wing. On the under surface 
the fifth spot of central band on primaries is often produced inwards, and in 
some few specimens the sixth spot unites Avith the enlarged spot below cell. 
Appears to be a common and widely-distributed species in Western China, 
but among the large number of specimens 1 have received I could only 
detect three females. This sex does not appear to have been hitlierto recorded.
