NYMPH ALID^. 
Timelsea albescens. (Plate xxill. fig. 9, .) 
Aryynnis maculata, var. albescens, Oberthiir, Etud. d'Entom. xi. p. 18 (1886) . 
Very similar to T. maculata, Brem., but on the upper surface of primaries there are only two 
black spots above the discal cell, and the black streak from the base in the submedian 
interspace is much shorter. The secondaries have the basal two thirds whitish, the discoidal 
cell slightly tinged with fulvous in some specimens ; the abdominal margin is unspotted ; the 
two lower spots in the cell unite with the inner central band, and the two upper ones in 
conjunction with the second one of the band form a straight series. Underside of all the 
wings as above. 
Expanse S 58-70 millim. 
I received six male specimens of this species from Wa-ssu-kow, where they 
were taken by a native collector in June. When M. Oberthiir described this 
as a variety of T. maculata he had seen but the one example sent him by 
M. I'Abbe David, who captured the specimen at Chapa, and only two of 
T. maculata. I find the differences between these two insects, as referred to 
above, are very constant, and in addition it may be mentioned that the 
undersides of the antennae of T. albescens are far less distinctly marked with 
white. 
Timelsea nana, sp. nov. (Plate xxill. fig. 8, $ .) 
Brownish black, banded with palo fulvous. Primaries have the discoidal cell crossed by two pale 
fulvous bars and closed by a third ; the central band is narrow and much augulated, preceded 
by a white spot on costa ; the submarginal band is lunulated and commences as a white dash 
from the costa ; the median nervure is pale fulvous, as also is the basal half of submedian, 
and there is a dash of the same colour from one nervure to the other. Secondaries have some 
obscure fulvous transverse markings on the basal area ; central band narrow and angulated : 
submarginal band narrow and lunulated towards coata ; ncuration brownish grey, and 
there is a marginal line of the same colour on all the wings, but broadest on the secondaries. 
Fringes black, tipped between the nervules witli white. Under surface of primaries ochreous, 
tinged with fulvous ; there are three black spots in the discoidal cell, and beyond these two 
central bands composed of black spots are placed as in T. maculata ; the submarginal band 
and marginal series of black sjiots are also very similar to the same characters in maculata : 
secondaries pale yellowish white ; there are three black spots in the cell with one below the 
first and one above the third ; the inner central IJack macular band is very irregular, the 
outer, composed of larger spots, is curved ; the submarginal band is formed of largo oblong 
black Rfwts. All the wings have a black marginal line, and the fringes are white, chequered 
with black at tho (i])s of the nervules. 
Female. Similar to the male, but tlie transverse l)aiids are paler and tho central one rather wider. 
Expanse 42-40 niillim. 
'I'liis species appears to occur only in Western China. I liave received it 
from Moupin, Wa-shan, Omci-slian, Chia-kou-ho, and Tluang-mu-chang.
