Var. tyrianthina, Butler. " Above brown, shot with purplish blue in the male and with purple 
in the female. Under surface of wings pale greyish brown, darker towards the base ; a brown 
fasciole, traversed by a pale line, at the end of the cell ; a broad, slightly tapering discal 
brown belt from the costal margin of each wing ; a submarginal brown stripe and a marginal 
brown border : secondaries with an orange patch enclosing a square of four black spots, 
bounded above by an incomplete W-shaped black line, and below by an alternately white and 
black fringe ; a black-edged whitish oblique band near the anal angle across the abdominal 
border, bounded internally by a brown band, and externally by an orange marginal border ; 
anal lobe and tail black, tipped with white ; pectus greyish, palpi white below, venter testa- 
ceous. Expanse of wings 1 inch 3-4 lines. Allied to T. nrata." (Butler, I. c.) 
Occurs at Kiukiang, Central China, Gensan in the Corea, and also in Japan. 
This form is smaller and darker than the type, and differs from it also 
in the brownish coloration of under surface; the central band on under 
surface of primaries tapers towards inner angle, above which it unites with the 
submarginal band. The differences do not, however, appear to be of specific 
value, as th(; brownish coloration of under siurface is found in some otherwise 
typical specimens of B. arata from Japan, and in other Japanese specimens 
the central band of primaries tapers as in var. tyrianthina. These are 
probably seasonal forms. 
Pryer records B. arata from Nikko, Fujisan, Gifu, and Ycsso, and says 
that it occurs in these places from May to July. 1 took specimens at Hako- 
date in August. 
Fixsen (/. c.) mentions specimens from Corea, and also a form with fulvous 
patches on primaries, which he figures. Elwes (Proc. Zool. Soc. Lond. 1881, 
p. 885) states that Bremer records it from Pekiu, and Maries from Kiukiang. 
The glandular patch towards costa of secondaries of male, the character of 
the markings of under surface, and the occasional occurrence of a fulvous 
patch on primaries of the female show that this species certainly belongs to 
Bapala, in which genus I have therefore placed it.
