LAMPIDINM 77 



Imago. — Male. Upperside purple with a silvery blue sheen, but varying somewhat 

 in colour, in some specimens the purple prevails, in others the blue, probably due to 

 climatic influences ; a slender black terminal line to both wings. Underside, ground 

 colour as in macropthalma, markings on both wings very similarly disposed, but finer 

 and more disjointed, the first line on the fore wings runs across the cell before its end, 

 and is disconnected hindwards, the continuation running from between the two lines 

 across the end of the cell to the hinder margin ; the short line a little beyond the end 

 of the cell is well separated from the third line, which is broken, the upper portion of 

 this third line is in an outward curve and stops at vein 3, being continued from that 

 vein at a little distance on the outer side, the fourth line, which also stops at vein 3, is 

 also outwardly curved ; on the hindwing the fourth line has no additional mark (as 

 in macropthalma), and on both wings the inner sub-terminal line has the upper three 

 marks of the forewing and all of the hindwing, formed of lunules ; tails black, tipped 

 with white. 



Female. Upperside very much as in the female of macropthalma. Underside as 

 in its own male. 



Expanse of wings, ^ % 1^^ inches. 



Habitat. — India, Burma, Andamans, Java, Amboina. 



Distribution. — Recorded from Sikkim, Bhutan, Assam, Cachar, Burma, and the 

 Andamans ; the type came from Java ; Felder's type of hermus came from Amboina. 



Note. — We have received many examples from the Khasia Hills, which cannot be 

 separated from this species, but they are all of a more uniformly blue shade above, and 

 every example on the undei'side has a dark blackish-brown patch on the centre of the 

 hindwing obliterating the linear markings ; this is probably an extreme Wet form ; we 

 figure the underside of one of them, fig. 3c, $. 



Note. — We have examined Felder's type of Lycsena hermus ; it is in all respects 

 identical with typical pavana.

Imago. — Male. Upperside dull purple-brown, both wings with terminal, very 

 slender black line. Underside pale greyish-brown with a slight chocolate tint; 

 markings slightly darker than the ground colour, indicated by their pale edgings.
