Hindwings reddish yellow instead of jellow. 



Felder's type-specimen agrees with hdena (L.), except in the reddish colour of 

 the hindwings.

This form combines the characters of the Javan hdena (L.) and the ludo- 

 Malayan helena cerberun (Feld.) ; the viale comes very close to cerherns (Feld.), while 

 the female, of which unfortunately only one example is known, is scarcely dis- 

 tinguishable from certain specimens of helena (L.). 



(J. Of the size of the Java specimens of helena (L.). Forewings black, with the 

 nervules, especially the two upper median ones, bordered with white ; these whitish 

 streaks are very narrow, and become clouded with Mack towards the cell. Hindwings 

 with a long yellow mark in front of the subcostal vein, as in cerberus; this mai'k 

 is nearly of equal breadth, much nari'ower than it usually is in cerberus, and does 

 not reach to the costal vein. The subdiscal black spots are very small ; they vary in 

 number from 1 to 5 ; the posterior one is much the largest. The spot between the 

 subcostal and upper discoidal veins, which is, together with that between the lower 

 median nervules, the last to disappear in helena, is only in one of my five males 

 marked. 



? . Forewings with as much white as in the palest individuals of helena (L.) ; apical 

 third of the cell' almost pure white, with two very thin black line.s, one in the middle, 

 the other in the direction of the upper median nervule ; the adnervular white streaks 

 more sharply limited than in helena (L.). The yellow region of the hindwings is 

 rather pale, probably owing to the specimen being somewhat worn. The subdiscal 

 black spots are large, and merged together with one another and with the black 

 marginal band. The basal-costal black area reaches as far as the origin of the 

 subcostal nervule, as in T. hdena cerberus ('l-Vld.).

Resembles in both sexes the Indo-ISIalayan T. helena cerberus (Feld.), I)ut differs 

 in the following points : — 



(J. The forewings are a little shorter; the abdominal margin of the hindwings 

 more broadly black, so that the yellow mark behind the cell is .smaller; the black 

 outer border of the iiindwiiigs narrower at Ihe nervules; tlie abdomen blacker 

 above. 



Forewings deep black on both sides; below with four geminate, white, 

 tubmarginal streaks at the median and the second discoidal nervules. The streaks 

 do not reach the outer margin of the wing ; the posterior ones are the shortest ; 

 that in front of the second discoidal vein is obsolete. At the apical third of the 

 upper discoidal nervule there are also some white scales,
