1888.] LEPIDOPTERA OF JAPAN AND COREA, 635 



stripe of primaries varies in width as it also does in tint, being some- 

 times rosy and sometimes dark purple, always bounded internally 

 with black, and often though not invariably edged externally 

 with white. The ocellus of primaries is as inconstant in shape as 

 in size, and in some examples small and round, in others linear, 

 and in others again large and oval, whilst the black outline, which is 

 usually only distinct on the inner edge of these ocelli, is in some few 

 examples entire and conspicuous. The submarginal and basal lines 

 are in the different specimens either sharply defined, faint, or quite 

 absent.

This is a variable species both as regards ground-colour and mark- 

 ings. Thus the former may be white or grey, and sometimes tinged 

 with green ; then the number of ocelli in central band and " rounded 

 internal spot" is not the same in any two individuals comprised 

 in my series of 15 specimens. The spot referred to sometimes has 

 three ocelli across its centre on one wing, but its companion on the 

 other wing has four. In all cases the number of ocelli, both in the 

 spot and central band, is greater on one side than the other. Again, 

 the shape of the central band is subject to niouitication, and stages 

 in the formation of the rounded internal spot from the lower portion 

 of this band are exhibited in the specimens in my Japanese series ; 

 thus between an example in which the band is entire from costa to 

 inner margin, and but slightly contracted below the middle, and a 

 specimen with the rounded spot completely formed and quite indepen- 

 dent, there are all the intermediate stages.

Brahmcea carpenteri, Butl., is the only form of B. certhia recorded 

 from the region under consideration. But this at best can only rank 

 as a variety of certhia.
