From Abyssinia southwards to Nyasa^ and on the west 

 coast from the Congo northwards to the Niger. 



This species has been confounded with the S.-Africau 

 representative of T. Desjardinsii by Mr. Marshall ; it is, 

 however, widely distinct, the female especially differing in 

 the typical (wet-season) form in its broad hind- wing border; 

 both sexes also differ in their less angular wings, with far 

 more regular arched inner edging to the border of the 

 primaries. In the dry-season form the border of the second- 

 aries is replaced by dots, but the markings on the under 

 surface are as indistinct as in the wet-season form, the apex 

 of the primaries being very delicately tinted with rose-pink. 



15. Terias Marshalli, sp. n. 



Terias Desjardinsii, Trim en & Marshall (not Boisduval). 



Wings much more angular than in the preceding species, 

 the inner edge of the outer border of primaries irregularly 

 sinuated, most prominently on the upper radial and two median 

 interspaces ; the outer border of the secondaries usually 

 narrower, always distinctly so in the female and most fre- 

 quently reduced to a marginal series of spots in that sex ; 

 markings below better defined, but especially in the inter- 

 mediate and dry-season forms, which show an additional 

 irregular subapical brown dash on all the wings and a rusty 

 flesh-coloured border to the primaries. On the upper surface 

 the three tolerably well-defined seasonal types differ chiefly 

 in the wndth of the dark outer border to the wings, that of 

 the secondaries being reduced in the dry-season to a narrow 

 dentated line in the male and a series of dots in the female. 

 Expanse of wings 35 to 45 millim. 



Ranges from the Albert Nyanza southwards to Kaffraria, 

 and on the West Coast from Angola northwards to the Niger. 

 (Fifty examples.)
