This species is the type of the genus IMvcronissa, and was 
wrongly identified in my paper above referred to as margari- 
tata, Moore (Urapteryx margaritata, P. Z. 8. 1867, p. 612), 
the type of which is unique, and which, though superficially 
like this species, belongs to another genus. 
Subfamily Eyvournz. 
Genus Hyposipra, Guen. 
Hyposidra kala. 
3 ?. Of a uniform dark slaty mouse-colour; wings with 
two transverse brown central bands, both bands indistinct, 
rather broad, rather close together, and curving slightly out- 
wards, the entire surface above thickly covered with very 
ninute whitish irrorations. Underside as above, the whitish 
irrorations thickened into a whitish smeared band on the outer 
margin of fore wings below the apical faleation.
