side by the apex of the fore wing being but slightly laved with 

 brown, and by the possession on the hind wing of an ultramedian 

 row of black spots varying in intensity and placed between the 

 veins, continuing on from the usual spot on the costa near the 

 apex to the inner margin. 



It is very difficult to arrive at a correct conclusion with regard 

 to the insects of this genus. Professor Poulton has recently 

 received a series from Lagos which contains examples of the 

 broad bordered form (L. aspidos mini), the typical L. lagyraHew., 

 and the form with the submarginal row of spots on the hind 

 wing below, named by me L. brenda, from Benin. This latter 

 I am now inclined to consider an aberration. It seems quite 

 possible that there is only one white variable species of Larinopoda, 

 as the black cell-spot on the under side of the hind wing of 

 L. eurema Pldtz is sometimes nearly obsolete, and this spot 

 constitutes its only distinction, specimens from Sierra Leone and 

 from Addah having a broad dark border to the hind wing almost 

 as in L. aspidos. It will be interesting to know the result of an 

 examination of the ancillary appendages. 



Liptena perobsoura, sp. n. (Plate XXXIII. fig. 13, § .) 



Female. Upper side : fore wing pale creamy white, costa, upper 

 half of cell, apex, and outer margin broadly blackish brown ; a 

 small brown spot at the end of the cell. Hind wing pale 

 creamy white ; outer margin pale brown divided by the white 

 nervules. The black spot of the under side at the end of the cell 

 showing through the wing. Under side pale creamy white, both 

 wings dusted with fine brown scales, densest towards costal and 

 apical margins of fore wing. Outer margins of both wings with 

 faint submarginal brown lines. Hind wing with an inner line 

 composed of faint brown lunules ; a small brown spot near the 

 apex and three near the base. Apical area of fore wing with two 

 semicircular faint brown lines much broken. Cilia of fore wing 

 brown, of hind wing white. Palpi pale yellow. Legs orange. 



Expanse 1-i- inch. 



Hob. Bitje, Ja river, Cameroons, 2000 ft., dry season (G. L.

Type, Mus. Druce. 



Near to L. alluaudi Mabille *, but differently marked. 



Liptena nubifera, sp. n. (Plate XXXIII. fig. 14, 3 .) 



Male. Upper side : fore wing pure white with the apex and 

 outer margin broadly blackish brown ; costal margin narrowly 

 and evenly blackish brown. A dark brown spot at the end of 

 the cell joining the costal border. Hind wing : apex and outer 

 marginal area broadly pale brown ; a minute brown spot at the 

 end of the cell. Cilia of both wings brown. Under side : both 

 wings much as above, except that there is a clearly defined
