Malk. — Closely allied to T. piiellaris, the only apparent difference being that it is 

 slightly larger. 



Under-side. — Primaries very similar to those of T. pnelhtris, the third black spot 

 near the posterior angle above the sub-median nervure being smaller and not 

 extending along the inner margin, as in T. puellaris. The secondaries do not differ 

 from the primaries in colour. Expanse 1"4 inch. 



Fkmale. — Like the male as regards the markings, the black marginal borders 

 being somewhat browner. 



U/idemde. — Only differs in having an irregular discal band on the secondaries, 

 from the costa to the first discoidal nervule. In some of the specimens which I 

 have examined, this band is nearly obsolete. Expanse 1"G inch. 



After careful examination of a good series lent to me by the Hon. W. Rothschild, 

 Colonel Swinhoe, and Mr. Crowley, I cannot separate T. dubius from T. vestalis, both 

 being the " wet-season " representative, as pointed out by Mr. Guy Marshall and 

 Dr. Butler. T. dubius is only a larger and more heavily marked form, not differing 

 from T. vestalis in anj' other respect that I can see. 



Colonel Swinhoe observes in a letter to me : " T. dubius is always uniformly much 

 the larger with the black bands broader, otherwise there is not much difference." 



T. intermissus is tbe " dry-season " form, being very much smaller and having the 

 marginal borders much reduced on both wings. The underside is very bright sandy 

 colour on the secondaries, the satne colour being strongly indicated on the apex and 

 hind-margin of the primaries. T. peehis is the yellow female of T. intermissus. 



Habitat. — North-AVestern India westwards to Southern Persia.
