vein, and after running a short distance joining the costa ; the 

 base of the second branch of the post-costal vein forms a short 

 transverse veinlet between the end of the costal vein and the end 

 of the first branch of the post-costal, its extremity being again 

 emitted from the end of the first branch and uniting with the costa 

 at a short distance beyond it ; the third and fourth branches of 

 the post-costal vein are free. The structure is, in fact, identical 

 with that of the veins in Th. Lucipor, male, represented in 

 plate 19, fig. 1 c, except that the lower disco-cellular connecting 

 veinlet forms a much stronger arch towards the base of the wing. 

 In the female, the second branch of the post-costal vein (plate 

 17, fig. 2 b) slightly coalesces with the outer portion of tlie 

 first branch, 2 a, (more closely, indeed, than is represented in the 

 space between the f and the letters 2 a,) thus proving most satis- 

 factorily the real nature of these apparently supplemental branches 

 of the costal vein. 



This beautiful species is dedicated to Aliris, the youthful poet- 

 king of Bucharia, whose love for Lalla Rookh, under his minstrel 

 name of Feramorz, has been so charmingly told by one of the 

 most delicious of modern poets.

The general appearance of the two sexes is nearly identical. 

 The male has a tuft of hairs at the base of the hind wings on the 

 upper side. The post-costal vein has only three branches ; the 

 first arising before the extremity of the discoidal cell ; the second
