far as black spot at end of discal cell. In the female all the wings 

 are buff with the dark colour of the male showing only as a broad 

 patch along the inner half of the wing, but not touching either the 

 base or the outer margin ; there are, however, distinct traces of a 

 narrow stripe of the dark colour extending from the top posterior 

 edge of the patch right through to the costa near the apex. Only 

 that the male has dark secondaries, the Gensan specimens are almost 

 alike in markings.' 



On the under surface the males are just as variable as above. In 

 one example all the wings are dark smoky brown with buff fringes 

 and a very slender buff costal edging, and in another specimen the 

 smoky-brown primaries are broadly bordered on the costa and outer 

 margin with buff, whilst the secondaries are buff tinged with smoky 

 browii between the discal cell and outer margin. This example has 

 a distinct black spot at the end of the cell on each wing, but similar 

 spots are to be traced, more or less clearly, in all the specimens. 

 In his descriptions of niphonis and squatnosa, Mr. Butler makes no 

 reference to these spots in the first-named, but he gives them as a 

 character of squamosa.

 A fine series, coll. Pryer, including four female specimens with well- 

 developed wings, and three examples of the same sex, in which the 

 wings are dwarfed, but with the markings reproduced in miniature. 

 As the female has not been previously noticed a description is 

 appended. 



2 . Primaries whitish, with an ill-defined dark discal spot and 

 ferruginous markings, the most conspicuous of which are a large 

 roundish patch at base between median nervure and inner margin, 

 a cloud on outer third towards apex, from the lower edge of which 

 a curved stripe, bordered externally with the whitish ground-colour, 

 runs to inner margin, and two angulated transverse lines on disk, 

 between which is an indistinct ferruginous shade ; near the costa 

 and towards apex is an elongated blackish spot and at external angle 

 tapering towards middle of outer margin is a purplish-grey patch 

 enclosing three blackish lunules bordered internally with whitish. 

 Secondaries pale whity brown, with a small brown patch near anal 

 angle, and an indistinct brownish submarginal baud. Under surface
