internal streak, the under siufaee varying from j);ilc huff to 

 lemon-yellow. Tlic t'emales nuicli resemble those of T. opal- 

 escenftf but the grouii(l-co!oiiring of the under surface is 

 yellower and the di.scal spots on the secondaries much more 

 j)roniincnt, whilst the orange costal streak is paler. In tlie 

 dry-season form of the female, apart from the slightly more 

 sandy reddish colouring of the apex and of the secondaries, 

 the absence of subapical spots and of the internal stripe on 

 the upper surface, and the presence of a tr.msverse tapering 

 brown streak from the costa of secondaries on the under 

 surface, serve to distinguish it from females of T. opalescens. 



12. Teracolus suhfasciatus.

 Ptychupteryx? ducissa, Dognin, Le N at u rails' te, p. 13J (18U1). 



The range of this species is much greater than was formerly 

 supposed. It occurs in Damaraland and Ovampoland, Eastern 

 Griqualand, Northern Transvaal, Matabeleland, Zanguebar, 

 Nyasa, and Uganda. 



From the rarity of the dry-season form, it seems probable 

 that it is confined to the drier parts of Eastern and East 

 Central Africa. The female is the sex described by M. Dog- 

 nin ; the male is brimstone-yellow like the wet-season form, 

 but with a clear orange apical patch. Ilewitsou has two 

 examples of the female from the Transvaal, but the orange 

 area on the upper surface of the primaries is somewhat more 

 restricted in these tiian in our Nyasa female.

Querimba, Mozambique. 



This is a wet-season form, and is not at all likely to be a 

 mere variety of T. chromiferus, which also is a wet-season 

 form occurring about 200 miles further northward. The 

 species is only known to me at present through the admirable 

 fiinire in Dr. Peters's work ; but I am satisfied that it is just 

 as distnict as T. elgonensis.
