the 'Genera of Diurnal Lepidoptera ' (p. 394) to ostrea, believing 

 Hubner's figure to represent a species distinct from Cramer's 

 otrea ; but I find, after a careful examination of a lengthened 

 series of specimens in the British Museum and others in my own 

 collection, that Hubner's figure well represents a male of Cramer's 

 species (otrea), whose figure (pi. 314. f. A, B) is that of a female. 

 The name ostrea, therefore, cannot be retained, as it was applied to 

 Hubner's figure, and not to the specimens which Prof. Westwood 

 erroneously determined as representing it. 



Yphthima nkwaka. 



Yphthima nareda, Hewits. Trans. Ent. Soc. 1865, pi. 17. fig. 7 

 {nee fig. 6). 



Male. Upperside brown : fore wing with single subapical 

 ocellus ; hind wing with two subanal ocelli, the former bipupilled, 

 and the latter with a single pupil of bright blue. 



Underside yellowish grey, partly covered with numerous short 

 brown strigae ; both wings with a narrow submarginal brown fascia : 

 fore wing with single bipupilled ocellus as above: hind wing with 

 three ocelli, the apical one very large, the anal bipupilled, the others 

 with single bright blue pupil. 



Female brown, externally with short pale strigae ; both wings with 

 single ocellus above. Underside as in male. 



Exp. If inch. 



Hab. Nepal. In Coll. W. C. Hewitson and F. Moore. 



Differs from Y. nareda, Kollar, in being somewhat larger, the 

 female striated above, the ocelli of both sexes much larger on the 

 underside, and the position of the ocellus on fore wing bein°- less in- 

 wardly oblique. 



Yphthima niblka. 



Upperside dark brown : pupils of ocelli blue : fore wing with a sub- 

 apical bipupilled ocellus (smaller than in Y. sakra) : hind wing with 

 two subanal ocelli ; male sometimes with only one subanal ocellus. 



Underside grey, with numerous short brown narrow strigse : fore 

 wing with ocellus as above, and a distinct brown submarginal trans- 

 verse fascia : hind wing with five ocelli, the two apicaf being the 

 largest and joined together, though having a yellow band be^eii 

 them ; the other three ocelli in a linear series from anal an<de, the 

 anal one bipupilled. 



Exp. ljL inch. 



Hab. N.W. Himalayas. In Coll. Capt. A. M. Lan» and F. 

 Moore. 



Differs from Y. sakra in its smaller size, darker colour above and 

 greyer below ; and may be distinguished by the difference of the 

 apical ocelli on the hind wing, which in Y. sakra have no intervening 

 yellow band. ° 



Yphthima avaxta. 



Upperside dark brown, with an indistinct bipupilled ocellus on 

 the fore wing, and two subanal ocelli on hind win°\
