in Western Africa (Ashanti) occurs a line Nymphalide, Momaleosoma Mens, Dm., 



the colouring and pattern of the female of which show a strong, but far from exact 

 resemblam to those of J). Chryiippui, the principal element of difference being the 

 I n l»\ ICInm of a hroad black hand, containing conspicuous white spots, which 



borri rs the hind wings. There is, however, in the British Museum, a variety of the 

 i l.leut, from Congo (in (J 1 S. Int.), which more nearly approaches the aspect of Chry- 

 ipi>»*. Compared wit h the type-form, it is smaller, and with more elongated fore wings ; 



w» 



tie z\ und-colonr is redder and clearer; the apical black of the fore wings occupies a 

 ^mailer ipaoe, while its white bar is broader ; and the border of the hind wings is nar- 

 rower, though still hroad and conspicuous*. Congo is one of the known habitats of

r have no doubt that Qodari rightly considered the Iodutta of Fabricins to be the 



of that author's Qea, as the difference in colour of the pale bands is the only distinction, 

 ul ther are several instances of allied Aerate in which the fulvous or yellow markings 



of the male are replaced by white in the female. Doubleday ('Gen. Diurn. Lep.'
