Zomba, December 1892 and January 1893. It is a singular thing that, at the time when M. Oberthiir described and figured his A. hauttecceuri and A. major and made the observation,-" Jusqu'a present on ne connaissait d'autre espece du genre Alcena que YAmazoula, Bdv., de Natal,"-one of these species had already been described eleven years, as A. nyassa, and the other five years, as A. interposita: one does not wish to be severe, but it looks almost as though this author had not gone over his ' Zoological Records' with any great care. 76 a. AL.ENA NYASSA, var. OOHRACEA. Similar in pattern to the type, but the belt across the centre of the wings buff-coloured in the male and wider than in the typical form; that of the female cream-coloured, wider on costa than in the typical female, and less inarched ; wings below suffused with buff. Expanse of wings, 3 31-36 millim, 2 35-36 millim. Zomba, December 1892 and January 1893. It is just possible that this may prove to be distinct from A. nyassa, but I am rather inclined to believe it to be a dimorphic form corresponding with the ochreous male of A. interposita, figured by M . Oberthiir as the male of his A. hauttecceuri. 77. ALPENA AMAZOULA. Alcena amazoula, Boisduval, Voy. de Deleg. ii. p. 591 (1849). Zomba, July 1892. 78. TlNGRA AMEN AID A.
