lias a (liy-scason u|)|)crsidc and tlic male lias a dry-season 

 underside; but the underside of the female exhibits wet- 

 season charaeters on the lower surfaee of the wings. The 

 nearest apj)roach to a wet-season firm of T. fausta is rcjire- 

 sented by a pair received iVoin Fao, barely distinguishable 

 from the male of my T. oriens. 



T. solan's of Swinhoc (and formerly of the Museum series), 

 = T. ori'ens {\y,nt.), Butler, is the true wet-season form of 

 India, and T. rosaceus the dry-season form ; but so intimately 

 is this connected with T. faustina and fausta through the 

 Persian examples above referred to, that it cannot be regarded 

 as a distinct s])ccies, but can only be spoken of as the Indian 

 development of T. fausta ; even as a race it could only be 

 arbitrarily separated by restricting it to Indian examples. 

 On the other hand, Mr. Marshall's action in placing the 

 Arabian T. vi as a synonym ot" T. fausta shows want of care, 

 or, perhaps, of discernment, in noting its entirely different 

 wing-outline.

Aden, Arabia. 



This species is allied to T. fausta, to which it bears a 

 general resemblance ; it, however, differs in its shorter, 

 broader wings, with more arched outer margin, in tlie much 

 yellower tint of the under surface, from which the discocellular 

 spots have almost wholly disappeared, whereas the discal 

 markings, though soft and blurred, are distinctly discernible 

 both in primaries and secondaries. T. vi is undoubtedly a 

 dry-season form which has no other phases, and is as distinct 

 a species from T. fausta as are T. fulvia and T. tripunctatus.

Khandesh, S.W. India. The type, in the Museum 

 collection, is said to be from Scinde, but this is probably an 

 error. Mr. Marshall has confounded T. Solaris with T. fausta 

 and T. fulvia with T. tripunctata ; but all are easily separable. 

 T. Solaris is simply T. fulvia, being based upon Wallace's 

 type of that species.
