the long tail is not spatulate, but linear, and is preceded by 

 two short tails at the ends of the lower sub costal and the dis- 

 coidal nervules, making five tails in all. In A. thaidina they 

 are merely indicated by notches. B. lidderdalii was first taken 

 by the celebrated hunter and naturalist, Lidderdale, in Bhutan, 

 at a height of 5,000 feet above the sea. It has since been taken 

 by others, but is still very scarce in collections. Nothing seems 

 to be yet recorded concerning the early stages of these two re- 

 markable Butterflies. 



To this Sub-family I add another very beautiful species 

 from North India and South China, which Schatz places in 

 the next Sub-family. It seems to me, however (pending a 

 thorough revision of the Equit'idce^ which cannot be much 

 longer delayed), to have considerable affinity to Armandia and 

 Bhutanitis, and hence I place it near them. It is true that the 

 fore-wings are broad, sub-triangular, and rather pointed, instead 

 of forming a long rounded oval; but the hind- wings are very 

 similar in shape, and, what is of more consequence, the short 

 upper disco-cellular nervule on the fore-wings, and the very 

 long incurved middle one are almost precisely of the same form. 



The sexes of Teinopalpus impenalis, Hope, differ very con- 

 siderably. The species measures from three and a quarter to four 

 and a half inches across the wings. In the male the wings are 

 of a silky green, with some darker, rather ill-defined stripes on 

 the fore-wings ; the hind-wings have a large orange band, 

 bordered with black, running from the costa for half the length 

 of the wing ; on the outside the black colour extends nearly to 

 the tip ; it is bordered externally by a suffused lilac-white 

 stripe, which, beyond the orange band, runs obliquely to the 

 inner-margin, being edged internally with black. On the 

 under side the wings are green towards the base, but the outer 

 two-thirds of the fore-wings are suffused with a rich orange; 

 the orange band of the hind-wings is more extended, and
