$ (?). Body covered with light brown and greyish hairs ; 

 ground-colour of thorax light brown, that of abdomen blackish. 



Head: antennae as in Psyclioda bengalensis. Legs brownish 

 grey, tarsi distinctly lighter, almost as in P. lacteitarsis when 

 viewed from certain directions. Wings with a depressed row of 

 elongate brown scales on each side of each vein, from the base to 

 beyond the middle of the wing, where they gradually become 

 narrower until eventually, towards the margin of the wing, they 

 are replaced by stiff hairs ; the scales lie close together, although 

 not always touching one another, and are long enough to overlap 

 those emanating from the adjacent veins. A distinct spot of 

 bristly black hairs at the tip of each vein, and apparently a slightly 

 clearer spot in the wing immediately in front of the vein-tip. 



Length 1^ millim. 



Described from a single specimen (apparently a female) in the 

 Indian Museum taken by Dr. Annandale at Kurseong, 4. viii.08. 



A very distinct species from all the others, readily distinguished 

 by the conspicuous, scaled veins.
