176 Mr. L. B. Prout on 



a strong tliougli not sharply defined band of light violet 

 irroratiou in distal area, approximately parallel to the sub- 

 terminal ; terminal line reddish, inconspicuous, deeply 

 orenulate, with a white dot at proximal extremity of eacli 

 tooth. 



Hind wing dark grey-brown, with a very narrow mid- 

 terminal area of violet irroration ; a crenulate dark terminal 

 line, in the distal interspaces of which the shading is pale 

 violet or whitish, fringe with slight pale irroration but 

 nowhere distinctly white. 



Fore wing beneath dull grey-brown, the base, costal edg?, 

 and broad distal margin darker. Hind wing beneath palest 

 at the base, in the (^ with the rest of the costal and a very 

 broad apical region darkened, in the ? with more than the 

 distal half of wings darkened, the two shades in neither sex 

 sharply defined. 



Bitje, Ja River, Cameroons, 2000 feet, wet season (G. L. 

 Bates), type S (April-March 1912) and 3 ? $ (Oct.-Nov. 

 1913, and undated). Also a ? from Entebbe, Uganda. 

 Belongs to the group Stenopis. 



18. Ercheia kebea boi'neensis, subsp. n. 



? .—46-49 mm. 



Thorax and fore wing (especially distal part; paler and 

 more ochreous than in kebea kebea from New Guinea ; tufts 

 at end of" patagia^^ still brighter ochreous. 



Hind iving less blackish than in kebea kebea, with some 

 ochreous-brown admixture. 



Underside much paler than in k. kebea, median band of 

 bind wing twice indented behind middle.

Perhaps the discovery of the ($ will show this to be a 

 separate species. The lobe on hind margin of fore wing is 

 possibly less developed than in true kebea. Neither specimen 

 shows any trace of the longitudinal line given by Hampson 

 (Cat. Lep. Phal. xii. p. 483) as characteristic of the ? , but 

 this is only aberrational in the sex. 



19. Ercheia amoena, sp. n. 



? . — 50 mm. 



Head and thorax whitish grey, mixed with dark brown ; 

 palpus ochreous-brown, mixed with dark brown ; patagia 

 and tegulse red-brown, mixed with white at edges. Meta- 

 thorax and abdomen above darkened ; underside of body
