260 J.EPIDOPTEBA FROM SOMALI-LAXD— HOLLAND. vol. xviii. 



Genus YPHTHIMA, Hubner. 

 YPHTHIMA CHANLERI, new species. 



Upper side brown, paler toward the outer margin and the apex. The 

 ocellar tract is not separated in any way from the adjacent portion of 

 the wings, the brown color shading by imperceptible degrees from the 

 base, where it is almost black, to the outer margin, where the wings are 

 pale wood-brown. There is a narrow dark submarginal line, which does 

 not quite reach the inner margin on either wing. On the j)rimaries there 

 is a large, sharply defined subapical ocellus, bipupilled, with the iris 

 orange-red, surrounded with a narrow dark-brown shade. Tpon the 

 secondaries there are two unipupillate ocelli of moderate size, one upon 

 each of the median interspaces. Upon the under side the primaries are 

 as upon the upper side, but slightly paler. The secondaries have in 

 addition to the two ocelli of the upijcr side another of equal size upon 

 the first costal intersi)ace, and a very small one adjacent to tlie inner- 

 most of the two on the median interspaces. The ocellus of the primaries 

 on the under side is bipupillate, as upon the upper side; the ocelli of the 

 secondaries are unipupillate. A narrow, slightlv irregular dark-brown 

 band runs from the ocellus at the costa across the wing to the inner 

 margin. The sex mark is not apparent upon the upi)er surface of the 

 primaries. 



Expanse of wings, 40 mm. 



The type in the National Museum collection, from tlie Tana Kiver, is 

 unique. 



Having carefully examined the descriptions of all the species enu- 

 merated in the recent monograph of this genus by Messrs. Elwes and 

 Edwards, I can find no account of any species from the African region 

 which applies to the specimen before me. Y. vinsoni comes nearest to 

 meeting the requirements, but the underside of the secondaries is totally 

 different.
