towards the anal angle as far as the lowest median nervule. This spot is of a brilliant 

 metallic, cliang«»able blue, much paler and less changeable externally. On the himhoin!; 

 is a large patch of the same rich blue, paler in the centre, occupying the whole disc of the 

 wing. Undkrside, bolh lahigs less black tlian above, the outer margin paler ; this pale 

 portion bounded internally by an undulated pale or whitish striga, becoming brown towards 

 its termination at the anal angle of the hindwing ; between this and the margin is another 

 less distinct similar striga. The forcwiiig has besides two fuscous strigcc in the discoidal cell 

 inclosing a paler space, and a third striga commencing on the costa beyond the cell, and extend- 

 ing obliquely nearly to the anal angle, slightly bordered internally with whitish. The hindwing 

 has a transverse fuscous striga near the base, and another commencing near the middle of the 

 costa, and reaching nearly to the anal angle. Just within the pale submarginal striga near the 

 costa is a round yellowisli spot, enclosing a brown one placed towards its outer margin, and 

 between the first and second median nervules a round black spot sprinkled with blue atoms 

 anteriorly, and surrounded by a yellowish and a black iris. Anal angle with a geminate spot, 

 composed of black and white atoms. Head, thorax and abdomen fuscous." {Doublcday, 1. c.) 



" The MALE has a patch of brown hairs capable of erection at the base of the hindwing 

 on the UPPEUSIDE. The apical angle of the forewing and the anal angle of the hindwing is 

 much more rounded than in T. odana ; the body is also much less robust. The branches of 

 the subcostal norvure of the forewing in this species are of tlie same number and almost 

 identical in tJieir arrangement with those of T. odana." {lVest7i)cod, 1. c.) 



The metallic blue band on the forewing of this species seldom extends to below the first 

 median nervule ; in a single specimen in the Indian Museum, Calcutta, it extends to the inner 

 margin, but even in this one the inner edge of the band is parallel to the outer margin, and 

 scarcely extends into the cell ; on the hindwing the metallic blue patch only reaches the first 

 median nervule and scarcely tinges the cell. It is not uncommon in .Sikkim, and is confined 

 to the north-east corner of Bengal, not extending so far as is known into British Burma. Mr. 

 Wood-Mason took it on Neniotha in Cachar in September and October.
