Pyrales from the Khasia Hills. 209 



Underside grey ; spot at end of cell and outer line pale brown, 

 the latter composed of spots ; body and legs whitish.

Cherra Punji. One example. 



The apex of the fore wings is rounded, and not acute, as is 

 generally the case in this genus ; there are indications of a 

 spot within the cell, but it is nearly obliterated by the inner 

 line ; the outer line is somewhat as in P. adhcesalis, Walker.

 Fore wings with some grey suffusion on the basal portion, 

 with pinkish ochreous uniform straight bands — one subcostal, 

 extending from near the base, connected with the costa by a 

 short band, to the costa near the apex, where it bends up ; 

 another from near the base runs along the wing below the 

 median vein to near the outer margin, then straight up sub- 

 marginally to the costa near the apex, outside the termination 

 of the other line, and is then joined to the apex by a small 

 loop ; also a third band runs just above the hinder angle, 

 where it is also curved up for a small space on the outer 

 margin. Hind wings with a broad suffused brown median 

 band. Underside as above.
