AMBLTPODIA GEOUP OP THE LYC2ENID2K. 25 



I am indebted to the kindness of Sir G. F. Hampson for being able to determine the 

 sexes of this species ; be kindly obtained for me a couple of specimens, which proved 

 to be a male and female, whose clasping-organs I mounted. The insect is recognisable 

 at a glance, but I have no doubt that the males have often hitherto been mistaken for 

 females, as the extent of blue is quite the same, and there is very little difference in 

 the colour. 



In de Niceville's collection there is now a good series of this insect, the specimens of 

 which are labelled with dates ; some from the Nilgiris are dated January 1 ; from 

 Atarem Valley (Tenasserim) February; the majority from the Nilgiris, however, were 

 taken in August and September. 



The genitalia are rather small. The tegumen is composed of a full hood, the hooks 

 having a strong muscular attachment, straightish as in Mahathala ameria, but with 

 a decided deflexion. The clasps are small, with the extremities projected well outwards, 

 which can be seen better in the figure (PI. IV. fig. 5) than it can be described. The 

 penis is unusually short and moderately robust.

Amblypodia (auctorum). 



Wings broad and ample. Primaries : costa variable, nearly straight, slightly arched 

 or decidedly arched, sometimes somewhat depressed towards the apex ; apex acute or 

 subacute ; outer margin occasionally straight or sometimes evenly convex, and some- 

 times concave below the apex, then convex ; inner margin generally, not always, 

 slightly hollowed in the centre ; costal nervure short but variable, never reaching as 

 far as the end of the cell ; first and second subcostal and upper discoidal nervules with 

 their bases nearly equidistant. Third subcostal nervule rising nearer to the apex of the 

 wing than to the apex of the cell, variable in length, but generally short ; middle disco- 

 cellular nervule rising some little way beyond the source of the upper discoidal, very 

 short, straight, outwardly oblique ; lower discocellular nervule variable, sometimes twice 

 as long or up to four times as long as the middle discocellular, straight, generally but 

 not always slightly inwardly oblique. Second median nervule rising some way from the 

 lower end of the cell ; lowest median nervule bent downwards and curved. Median
