"Allied to T. batfus, Cramer." {Batler, I. c.) 



Var. tyrianthina, Ikitler. " 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 iuch 3-4 lines. Allied to T. arata." {Butler, I. c.) 



Occurs at Kiuldang, 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 broA\Tiish 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(i brownish coloration of under surface is found in some otherwise 

 typical specimens of R. 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 R. arata from Nikko, Fujisan, Gifu, and Yesso, 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. Loud. 1881, 

 p. 885) states that Bremer records it from Pekin, and Maries from Kiukiaug. 



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 

 RajJala, in which genus I have therefore placed it.
