The hiudwiugs have a large yellow mark between the coi^tal and subcostal veins; 

 this mark is shaped as in T. helena cerberus (Feld.), i.e. it is broadest towards the 

 margin and reaches here the costal nervure. The jellow spot behind the cell extends 

 along the lower median nervule as far as a third of the way from the cell to the end of 

 the ner\ule. The outer margin is rather strongly dentate; the black border is more 

 deeply scallojjed than it usually is in helena (L.) and helena cerberus (Keld.j. There 

 are four black subdiscal sjiots : the fii-st stands between the subcostal and upper 

 discoidal veins, and is as small as the third, which is situated between the upper 

 median nervules ; the second is point-like, and stands before the upper median vein ; 

 the fourth, which is about six times the size of the first and third, stands between the 

 lower median veins, and is merged together with the marginal marking. 



Abdomen yellow; upper surface black, with the middle of the fourth and fifth 

 segments feebly fuscous, and the edges of the fifth to seventh segments narrowlv 

 yellow. 



?. The black border to the hindwings narrower at the nervules than in T. helena 

 cerberus (Feld.J. The abdomen is blacker above ; the yellowish white colour of the 

 sides is less extended ; the five basal segments are black below, edged with vellow, 

 instead of yellow, spotted with black. 



The adnervular white streaks of the forewiugs are very prominent on both sides, 

 narrow, and sliarply defined ; those at the subcostal nervules are much clouded with 

 black, except at tlie cell ; they are united in pairs ; the bases of the two streaks 

 between the two lower median veins are shaded with black ; the streak behind the 

 third median nervule is obsolete, except towards the outer margin ; the two streaks 

 at the submedian nervure are broad and short, and have the same position as in 

 helenia (L.). 



The basal-costal black region of the hindwings does not extend beyond the origin 

 of the submedian nervule ; before the subcostal vein there is a yellow submarginal 

 mark ; the subdiscal black spots are joined to the black marginal border by means of 

 a few black scales; the submarginal and the subdiscal black spots at the anal angle 

 are merged together with the black abdominal margin above. Below, that submarginal 

 spot is partly encircled by a yellowish buff half-ring. The abdomen is much darker 

 than in the other forms of helena (L.) ; the sides are feebly greyish yellow, the 

 lateral black spots (upon the stigmata) are large. Below, the five basal segments 

 are brownish black, with the hinder edges thinly yellow; the sixth and seventh 

 segments are yellow, with a black spot on each side; the eighth and ninth yellow.
