176 Mr. L. B. Prout on 
a strong though not sharply defined band of hght violet 
irroration in distal area, approximately parallel to the sub- 
terminal; terminal line reddish, inconspicuous, deeply 
crenulate, with a white dot at proximal extremity of each 
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 
uowhere 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 2 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 & (April- -March 1912) fal 3 2 2 (Oct.—Nov. 
1918, and undated). Also a 2 from Entebbe, Uganda. 
Belongs to the group Stenopis. 
18. Ercheia kebea borneensis, subsp. n. 
2? .—46—-49 mm. 
Thorax and fore wing (especially distal part) paler and 
more ochreous than 1 in kebea kebea from New Guinea; tufts 
at end of “ patagia”’ still brighter ochreous. 
Hind wing \ess blackish than in ‘kebea kebea, with some 
ochreous-brown admixture. 
Underside much paler than in k. kebea, median band of 
hind wing twice indented behind middle. 
Bidi, Sarawak, 1907-08 (C. J. Brooks), 2 2 9. 
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 amena, sp. n. 
2 .—50 mm. 
Head and thorax whitish grey, mixed with dark brown ; 
palpus ochreous-brown, mixed with dark brown; patagia 
and tegule red-brown, ‘mixed with white at edges. Meta- 
Sie. and abdomen abore darkened ; underside of body
