Originally described b}- Dr. Gerstaecker from Ndara, this species appears to be 

 entirely confined to East Africa, and, in fact, occupies nearly the same area as 

 T.punicem. It has been sent in some numbers from the Teita District, but has 

 not as yet been found so far in the interior as T. imnicem. As to the supposed 

 occurrence of the species in Somali-land, I have explained below how I came to 

 make this mistake. 



The females of the present species appear to vary considerabl}^ especially in the 

 so-called " wet-season " phase, and this variation reaches its extreme in the white-and- 

 black form called T. foliaceus by Dr. Butler, which was first united to T. hetcera by 

 Mr. Guy Marshall, and is now admitted to be identical by Dr. Butler himself. 

 Although I have treated T. hetcera and T. puniceus as distinct species, following the 

 arrangement in the British IMuseum, I am inclined to believe, with Mr. Guy Marshall, 

 that the two are really not to be separated. 



The chief difference between them is that T. hetcera has six ovate crimson spots 

 on the apical portion of the primaries instead of five, as in T. puniceus. The sixth 

 spot, however, is often so small as to be practically obsolete, so that this character 

 seems not to be constant. In the female of T. hetcera the inner edge of the hind- 

 marginal border on the primaries is not dentated, but has the outline indicated in a 

 curved line. There is, however, one specimen from Taru in the British Museum, 

 which is there referred to T. hetara, and which shows slight indentations, so that 

 this character also appears to be inconstant. 



The males of T. hetcera show a post-median row of spots on the underside of the 

 primaries, and on the secondaries the transverse band is more strongly pronounced 

 than in T. pimicem. These characters are greatly in evidence in the females of both 

 species. So far, I have not seen any indications of the apical spots on the primaries
