10. Leptophobia subargentea t sp. n. 



(. Above very similar to the same sex of L. tenuicornis, 

 but the base of primaries blacker, the white markings more 

 cream-coloured, the large patch barely extending above the 

 second median branch (so as to leave a much wider interval 

 between it and the subapical bifid spot) ; secondaries much 

 less blue, the inner bordering of the much larger creamy 

 white patch being rather silver-grey. Primaries below with 

 costa and fringe sulphur-yellow, apical area silver crossed by 

 black veins ; white area rather more extended basally than 

 above and pure white, subapical white spot slightly broader : 

 secondaries silver, with black veins ; basal lobe daffodil- 

 yellow in front, saffron behind. Body normal. 



Expanse of wings 58 millim.

This species seems to approach L. penthica, but with no

 apex of primaries below silvery rather than nacreous. The
