15. Teracolus chromiferus. 



Teracolus chrom'J^erut, Rothschild, Novit. Zool. vol. i. p. 533 (1894). 



Most frequently received from Zanzibar, from which 

 locality we have a pair from the Godmau and Salvia collec- 

 tion ; the example in Hewitson's collection is also from this 

 locality. It, however, occurs southwards certainly as far as 

 the Zambesi River, and, according to Marshall, even as far 

 as Beira, whilst Dr. Ansorge obtained it in German East 

 Africa. 



16. Teracolus pumceus.

 figs. 5, 6. 



The wet-season form of this species has recently been 

 received from Mni, near Mombasa ; it is slightly larger than 

 the typical dry-season form, and the magenta-red extends a 

 little further along the costa, but not upon the outer margin ; 

 the veins above are more heavily blackened and terminate in 

 black marginal dots ; on the under surface the apex of pri- 

 maries and the whole of secondaries are creamy buff, the 

 costa of secondaries narrowly saffron-yellow towards the base, 

 and the transverse ray is either absent or represented by 

 black-brown dashes. The female is either white or bright 

 yellow above, and greyish lavender or yellow, sparsely irro- 

 rated with greyish, below; tlie markings are somewhat 

 similar to those of T, heta^ra, but the borders perhaps rather 

 less heavy, more nearly resembling the dry-season females of 

 that species. T. pumceus ranges from Wadelai through the 

 Victoria Nyanza south-eastward to Mombasa. 



17. Teracolus hetcera. 



S. CaUosune hetara, Gerstaecker, Arch, fiir Naturgesch. 1871, i. 



p. 367 ; Van der Decken's Rei-sen in Ost- Africa, iv. 2, p. 305, pi. xv. 



fig. 2 (1873). 

 2 . Teracolus foliacetis, Butler, P. Z. S. 1894, p. 573, pi. xxxvi. fig. 7. 



The range of T. hetcera appears to be from the Sabaki 

 valley southwards to Zanzibar, meeting with T. puniceus at 

 Mombasa only. 



T. foliaceus is a dark form of the wet-season female : the 

 dry-season male chiefly differs from that of the wet-season in 

 the less-defined black veining and marginal dots and in the 

 rosy under surface ; the secondaries show faint traces of a 

 transverse bar. A pair of this form was in the Godman and 

 Salvin collection.
