tnings from apex. Judging from Cramer's figure {Pop. 

 Exot. i. t. 96, D, e), M. Silenus lias only a slightly paler 

 fascia near the hind-margin of the forewings, with no 

 trace of ferruginous ; and the underside is generally much 

 darker than in M.JiceduIn, and without yellowish clouding. 

 Boisduval's figure purports to represent Loxura Alcidcs 

 from " Gueuee ;" it is evidently that of rather a small $ . 

 In pattern and colouring (only the upperside being 

 depicted) it agrees fairly with the Southern form, except 

 that along hind-margin the ferruginous border has a narrow 

 black edging, and that the outline of the hind-margin of 

 the forewing is not elbowed. If the locality of Boisduval's 

 example be correctly recorded, it would ap])ear that 

 M.Jicedula, or a very near ally, inhabits Western Africa 

 in company with M. !Silenus.
