Zomba, December 1892 and January 1893. 



It is a singular thing that, at the time when M. Oberthiir 

 described and figured his A. Jiauttecceiiri and A. major and made 

 the observation, — " Jusqu'a present on ue connaissait d'autre espece 

 du genre Alcena que VAmazoula, Bdv., de Natal," — one of these 

 species had already been described eleven years, as A.nj/assa, 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 Eecords ' with any great care. 



76 a. Al JiN'A NTASSA, var. ochracea. 



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, S 31-36 millim, $ 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 beHeve it to be a dimorphic 

 form corresponding with the ochreous male of A. inter^^osita, 

 figured by M. Oberthiir as the male of his A. hauUecoeiiri.
