94 MR. A. G. BUTLER ON NEW [Feb. 7, 



brown discocellular spot with white pupil, and six minute black 

 marginal dots between the veins. 



b. Secondaries below sulphur-yellow throughout, two additional 

 brown spots, on the interno-median and second median interspaces. 



<% Secondaries below flesh-pink with yellowish margins, the 

 whole surface mottled with indistinct olive spots, a dusky longi- 

 tudinal streak through the cell ; other markings as in var. a, but 

 less distinct. 



d. Secondaries inclining to ferruginous excepting towards apex, 

 where the ground-tint is yellow, a yellowish streak above a black- 

 mottled dusky longitudinal streak through the cell ; the whole 

 remaining surface mottled with olive and black ; other markings as 

 in var. b, but larger. 



In addition to the above modifications, the black border on the 

 upper surface of the primaries varies both in width and length ; but 

 its inner edge is always more or less dentate-sinuated. 



5. TEEACOLUS VENUSTUS, sp. n. 



<S . Above like a small specimen of T. aurigineus, but with narrow 

 external black borders to the wings, a smaller spot at the end of 

 the discoidal cell of primaries, and the black band of secondaries 

 terminating at third median branch ; below it also differs in having 

 the apex and outer border of primaries and ground-colour of 

 secondaries sandy buff instead of sulphur-yellow. Expanse of wings 

 36 millim. 



Kilima-njaro (F. J. Jackson). 



Allied to the preceding is a species of which we have received no 

 less than nine specimens from Somali-land, but which, from an 

 omission to examine them individually, I confounded with the 

 T. chrysonome of Klug ; I describe it as follows : 



TERACOLUS HELVOLUS, sp. n. 



Nearly allied to T. chrysonome, the wings a little shorter and 

 smaller; the indication of a band across the secondaries much more 

 decided ; the discal zigzag band of primaries below ending in a 

 black spot ; the apex and outer border of primaries and entire 

 ground-colour of secondaries on the under surface flesh-pink instead 

 of sulphur-yellow. Expanse of wings 33-35 rnillim. 



T. chrysonome measures 40-44 millim. in expanse ; it is a wider- 

 ranging species than T. helvolus, which is probably restricted to 

 Somali-land. 



6. TERACOLUS COMPTUS, sp. n. 



Nearly allied to T. antigone, which we have in both sexes from 

 Accra, out larger, the wings decidedly longer, the black external 

 border of primaries narrower ; the black spots of secondaries much 

 smaller ; the internal band on the male more or less prominent, 

 more so than in our specimen of T, antiyone, in both males before 

 me ; the orange apical patch of the male broader and not so red ; 

 the black apical patch in the female connected by a line of black
