 ochreous ground-colour ; in both which respects, but especially

in the latter, the two forms under notice, together with iV. 

 exaleuca, Karscb,* from Camaroon, and ffi. ivoodicardi, E. M. 

 Sharpej from British East Africa, constitute a section apart 

 from the other known Ethiopian ones, and approaching the 

 group represented by the well-known Palaearctic species iV. 

 lucilla, Fab., ranging from Central Europe to Japan. It is 

 remarkable that of these four forms, the extreme West 

 African species, N. exaleuca, is, in the shape, disposition, and 

 longitudinal extension of the markings, more like than any 

 of the others to N. lucilla. 



" The 3 and $ of the new form here described were presented 

 to the Hope Department by Mr. G. A. K. Marshall, who 

 kindly informs me that both were taken — the $ by himself, 

 and the <$ by Mr. C. F. M. Swynnerton — in a remarkable 

 isolated patch of heavy forest on the top of Mt. Chirinda 

 (about 4,500 ft.), in the Melsetter District (formerly known 

 as 'Gaza-land') in S.E. Rhodesia, situated quite close to the 

 Portuguese border and about 150 miles by road south of 

 Umtali. The $ was captured in March, and the $ on 18th 

 October, 1905. + 



" It is a pleasure to associate with this interesting new form 

 the name of Mr. Swynnerton, a naturalist who is a fellow- 

 worker with Mr. Marshall in the richly productive region of 

 Rhodesia. 



" There is an obvious similarity between the narrow-banded

% Since the above was written the Hope Department has received from 

 Mr. Swynnerton 3 $ 6 and 2 9 9 , taken in the same locality, but at a 

 lower elevation, viz. 3,800 ft. The dates of capture of the 6 6 are 

 noted as respectively 1st to 6th March, 5th April, and 10th April, 1907, 

 and of the 9 ? respectively as 25th March and 13th April, 1907. These 

 additional examples of both sexes agree very closely on both surfaces of 

 the wings with the individuals above described — the only noticeable 

 difference being in the smaller size of the inner-marginal white spot on 

 the upperside of the fore wings. As regards size, however, the three S $ 

 have a rather larger expanse of wings, viz. 1"9-10|'", and one of the 

 9 9a rather smaller expanse, viz. 1" 11 \'". — R. T.
