S . In the pattern of the wings, on both surfaces, this 

 form differs very little from the type form ; but the 

 abdomen is entirely a deep brownish black, the anal 

 valves being dark red brown ; the abdomen is also rather 

 hairy, and conveys the idea of T. Brookeana, Wall. 



Hab. : Mount Battak, Sumatra. 



? . Anterior wings light brown, pattern the same as on 

 the type form, except that the intercellular dark area 

 terminates in 2 dentate projections at near the end of the 

 cell in the grey area ; in the type form the grey inter- 

 cellular area is only traversed by the pseudoneura. 

 This may be a means of always distinguishing the 2 

 of this variety from that of the type form. Posterior 

 wings similar on both surfaces to the type form, 

 but the yellow internervular spaces are narrower, and the 

 markings more slim, those bounded by the 1st median 



nervule and the submedian fold or sinus are margined 

 with white, and the abdominal margin has little or no 

 white ; the abdomen is entirely brownish black and hairy, 

 probably as a protection from mountain cold. 



Hab. : Battak Country, Sumatra. 



The melanism of the abdomen of both sexes in this 

 var. is remarkable, as it is not met with in the Javan type 

 form, which is also a high mountain region insect. 



I am indebted to the great kindness of Mr. Snellen, 

 of Rotterdam, for the loan of the examples from which 

 my figures are drawn, and also for examples of the type 

 form for dissection. 



Examples of the two sexes of this var. are also in the 

 museum of the Hon. W. Rothschild.
