Under surface much paler than above, bronze-brown, with a paler triangular patch at centre of outer margin of all the wings, and with the costal area of secondaries paler to just beyond the white belt; primaries with three white spots forming an elongated triangle in the cell, four in a semicircle beyond the cell, and seven crossing the disc as above, but larger; belt of secondaries as above ; pectus black, spotted with white and clothed with tawny hair; venter fuliginous, with sordid white central stripe ; legs striped with white longitudinally. Expanse of wings 59 millim. Kantorongondo Mt., 15,900 feet alt., Nyika, April 15th, 1895. " Black and white Admiral. Grass-green ova" (R. ft). This extraordinary species is represented by a single example, the wings of which on one side are badly shattered; it does not appear to be nearly related to any other species in the genus, but perhaps should form a distinct section next to N. marpessa, though in some respects it more nearly resembles the ^Australian A. shepherdi. 25.

" Reddish-brown Wall" (R. ft). This is the form which I have hitherto regarded as B. acheloia ; but Prof. Aurivillius has pointed out to me that B. cora is that race, a much rarer form, having the under surface of the secondaries belted with dull reddish argillaceous. B. vulgaris differs very-little from B. goetzius of Herbst. The species of Acrceincs in the present collection are, as usual in African series, well represented, and in the present instance are of exceptional interest to us. 27. ACR.EA JOHNSTONI. 3 .
