tinge in the region of the apical patch. Hind-wings narrowly bor- 

 dered with black, a marginal row of dark spots as in the male, the 

 anterior three being fused into a marginal band ; a submarginal 

 series of dark spots occupying the interspaces, that in the radial 

 interspace (between the radial and third median veins) being the 

 largest and darkest. The base shows a greyish clouding, which 

 is slightly prolonged towards the anal angle. A minute black 

 discoidal spot present. Fringes pale reddish. 



Underside. Fore-wings white; inner four-fifths of cell washed 

 with pale lemon-yellow. Apical patch divided by a row of dark 

 submarginal spots, corresponding to those on the upper side but 

 more discrete, into an outer reddish-ochreous and inner orange- 

 ochreous portion, the contrast between the two tints being much 

 less marked than in the male. The black discoidal spot is not larger 

 than on the upper surface. A pale greyish bar runs parallel with 

 and close to the inner border, ending near the anal angle in a fairly 

 definite dark patch. Hind-wings as in the male, but slightly darker 

 and with a somewhat more pronounced dusky suffusion. The 

 submarginal spots are much larger than in the male. The discoidal 

 dot is very slightly touched with orange. There is an orange streak 

 along the costa, and a pale Indian-red patch at the origin of the 

 median vein. 



In both sexes the row of submargmal spots in the median and 

 submedian interspaces of the hind-wing (m the male visible only 

 on the under surface) conforms more nearly to the curved margin 

 of the wing than is usual in this group of Teracolus. 



1 c^, 3 $ $ (Taveta), in Hope Collection, Oxford. The male 

 and one of the females were bred by the Rev. K. St. A. 

 Rogers, emerging on August 6, 1905. A second female was 

 captured on August 7, 1905, and a third female on July 16, 

 1910, both by Mr. Rogers. 



The species may be an East African representative of 

 T. halyattes, Butl., the type of which came from Natal. 

 T. halyattes is regarded by Butler as the dry-season phase 

 of his Teracolus lais, the type of which also came from South 

 Africa. The representative of T. lais in the Nile district 

 is doubtless T. ephyia, Klug, and the present form, inter- 

 mediate between T. lais and T. ephyia in geographical 

 position, is in some respects intermediate also in character. 

 One feature that serves to distinguish it from the type of 

 T. halyattes is that the submarginal series of spots on the 

 hind-wing tends to form a curve more or less conformable 

 to that of the wing-margin, whereas in T. halyattes, as gener-
