174 ZOOLOGICAL EESULTS OF THE EUWENZOEI EXPEDITION. 



from the apex of this border a transverse band of the same colour runs across the wins;, 

 beyond the end of the cell, as far as vein 1^; between this and the outer margin is 

 some faint darker shading, and along the margin some vague lunules of greyish scales 

 are sometimes visible. 



2 ■ — Uppeeside. Paler than that of the male. Fore-win^ with the elongate spot in 

 space 2 more displaced outwardly, the spot in space 3 larger ; while in the subapical 

 band the spot in space 8 is not longer than that in 7. liind-imng clothed at the base 

 with ochreous hairs. 



Underside. The ground-colour is much paler, especially in the hind-wing, in which 

 the costal border of brown-pink is also much paler and less pronounced. 



Antennae of the male white above, buff below, except the apiculus which is brown 

 on both surfaces. In the female, the antennae are brown above, save for a few white 

 scales at the end of the club ; below buff, which colour spreads a little round the 

 joints of the shaft and is visible from the upperside. 



Head in both sexes brown above ; in the male with w'hite scales between the 

 antennae, in the female with buff scales posterior to them. 



Thorax and abdomen seal-brown above, the female with a few raw sienna scales 

 at the end of the abdomen. Below the violaceous brown predominates, the legs 

 remaining brown-pink. 



Palpi below brown-pink. 



2 d c^ , 2 ? ? . Mubuku Valley, E. Euwenzori, 6000-13,000 ft. 13, 15, 21. i. & 

 1. iii. 06. 



Ceratrichia woLLASTONf, sp. n (Plate V. figs. 13 c5' ; 14, ? .) 



Expanse: 6 31 mm., $ 31 mm. 



Nearest C. flava Hewitson in wing-shape, but paler in colour, with the fore-wing 

 divided about equally into an apical dark half and basal lighter portion, while in 

 Jlava the dark border is subparallel to the external margin from the tornus to vein 4 

 and then angulated along the vein and running obliquely to the costa. 



<3 .■ — Upperside. Gamboge-yellow : fore-wing with the apical half rich seal-brown, 

 this area terminating internally in an even curve from the tornus to mid-costa, which 

 touches the end of the cell ; a minute ray of dark scales stretches for 2 mm. from the 

 base along the costal nervure ; the basal half of the costal margin very narrowly edged 

 with brown : hind-wwg with a patch of the dark brown at the apex of the wing and a 

 few dark scales at the base of the internal margin. 



Underside. Fore-wing : ground-colour the same as above, but much more orange 

 towards the costal and external margins and paler towards the internal margin ; the 

 dark scaling covers the same area as above, but is much reduced in density, hardly 

 traceable costalwards, and dusted with dull gallstone-yellow scaling at the external 

 margin. At about I'O mm. from the external margin a small brown-bordered silver spot 

 lies in interspaces 6, 8, 9, 10. On costal margin lies another, and one is situated ia
