streaks on the veins running from the margin to the post-

Pleurona simillima, nov. 
&. Of a uniform ochreous-fawn colour ; markings above 
and below similar to those of P. falcata, Walker, of which I

is not falcate, it is slightly arched towards the apex, which is 
not produced, and the outer margin is evenly rounded, not 
excurved before the middle as in falcata, and the cilia is 
uniformly dark brown, without any white below the apex.

Zethes limbalis, nov.

Assam ; the fore wings are longer and the outer margins of 
both wings are crenulate, in inornata they are smooth ; colour

and on the hind wing bent inwards on the internal vein; this 
line is edged with pale grey on both wings and has a broad
