^ . Fore wing nearest to T. Bernice of Hewitson, but differnig 

 in tlie extent of the black apical portion, which is much wider ; 

 there is no black spot at the end of the submedian nervure and the 

 first medial nervule ; the grey dusting at the base of the wing is 

 much lighter and does not extend so far as in T. Bernice, Hind 

 wing has the hind marginal border much broader and darker, there 

 being three large distinct black spots, one on the second subcostal 

 nervule, one on the first radial nervule, and the third on the third 

 median nervule ; there are three more spots on the hind margin, 

 but they run together, making a complete black border towards the 

 anal angle. Under side of fore wing is very similar to the upper 

 surface, the black at the apex being very distinctly marked ; there 

 is only a slight mdication of black along the costa ; the base of fore 

 wing is yellow. Under side of hind wing : the hind wing has a com- 

 plete broad black border on the hind margm, commencing a little 

 above the second subcostal nervule and extending below the sub- 

 median nervure. Nearly the whole of the basal area is suffused 

 with yellow, and costa strongly marked with same. The <? of 

 this species is closely allied to T. Bernice, but is distinguished by 

 the breadth of the black hind margin. Exp. 2:^ in.

 but in the fore wing it differs in the larger extent of grey above the 

 submedian nervure ; the hind margin and apex are also much 

 darker. Hind wing dusky brown, with the hind marginal border 

 rather distinctly marked. Under side of fore wing is almost white, 

 with the apex black, and four black spots, one at the end of each 

 nervule from the second discoidal, or radial nerviJe to the first 

 median nervule; they are all slightly tinted with yellow; base 

 yellow. Under side of hind wing is paler than on the upper surface,
