This lovely little species will come between aronya, Feld., and 

 argentea^ Stgr., but may be known from either by the very distinct 

 colouration of the upper surface, which is very close indeed to that of 

 Thcha, Hew., but is much more silvery and with very much less purple. 



Akiiopala Brahma, n. sp. 



$. Ujjper-side : botli wings rich purple, much the same colour as Hercules, 

 Hew., but not lustrous, though in some lights there is a slight lustre visible ; costa 

 of primaries with an exceedingly fine brown marginal line ; fringes brown, with no 

 anteeiliary line at all to either primaries or secondaries ; eosta of secondaries rather 

 broadly brown, and abdominal fold brown. Under-side : both wings very dull 

 greyish-brown, with all the markings inclined to obsoletion, specially in the prima- 

 ries ; the only marking really visible in the primaries is the transverse band, which 

 is just discernible, it is apparently composed of five spots, the first three placed in a 

 slight arc, the fourth and fifth directly below each other and shifted very slightly 

 inwards. In the secondaries the four basal spots are present, the upper two being 

 barely discernible, the three below each other across the cell are fairly distinct, as 

 also is that closing the cell, below which is a trace of a small triangular one ; trans- 

 verse band composed of eight catenulated spots, the third being shifted right 

 outwards, just touching the outer edge of the second, fourth shifted slightly outwai-ds, 

 fifth and sixth with a very slight outward inclination, seventh angular spot dislo- 

 cated right inwards and touching the eighth spot; there is a slight trace of a 

 submarginal fascia, a very fine |iale ante-marginal line. Expanse, 42 mm. 



9 . Both wings bluish-purple. Primaries broadly blackish-brown to near end of 

 cell, where this colour suddenly widens and forms a large subtriangular blackish angular 

 patch ; outer margin broadish, decreasing rapidly from the second median nervule 

 to the anal angle. Secondaries with broad brown costa and narrow brown outer 

 margin, increasing slightly as it neavs the anal angle ; abdominal fold greyish. The 

 only ? before me has been stained to a very dull violet, but nearly a third of the 

 left secondary is of the original colour, and I have taken this as the ground-colour 

 of the whole wing. There is no doubt as to the discolouration. Under-surface 

 precisely as in the male, but all the markings larger and fairly distinct, and in the 

 primaries the three increasing cell spots and that in the lower median angle are 

 discernible, all the spots ax"e light edged, those of the primaries are more obscure 

 than the secondaries. Expanse, 45 mm. 



Hah. : Perak. 



This species will come next to hypomuta, Hew. ; it can, however, 

 be recognised by its larger size and the brighter purple of the upper 

 surface, also by the obsoletion of markings beneath, the transverse 

 bands being different in shape, and by the lack of any metallic scales 

 at the anal angle of the secondaries.

 S . Upper-side : both wings pale azure blue, slightly lustrous ; primaries with 

 the costa broadly blackish almost to the cell margin, and increasing in width towards
