468 Dr. A. G. Butler—A Revision 
The female wrongly referred to 7’. halyattes is referable to 
typical 7. dthonus (the smaller dry-season form), 
60. Teracolus achine.

Ranges from the Cape to Natal, the Transvaal, and appa- 
rently northward as far as Nyasaland. 
The wet and intermediate forms of this species have a well- 
defined internal stripe on the upper surface of the primaries ; 
the apical patch in all the phases is bright vermilion, with a 
crimson tinge, but on the under surface the subapical orange 
bar is weak and diffused ; in the intermediate and dry-season 
forms the under surface of the secondaries is irrorated and 
striated with grey upon a pale pink ground; the dry-season 
form (7. simplex) differs in having no internal blackish stripe 
on the primaries and no costal stripe on the secondaries of 
the male, and in the feebleness of all the other blackish 
markings on the upper surface. 
Subspecies Teracolus Triment.

A representative form of 7’. achine apparently confined to 
the Eastern side of Africa from the ‘Transvaal northward as 
far as Manboia. ‘The typical (wet-season) form is generally 
more heavily marked above with black than in 7’. achine, the 
male even sometimes showing traces of the angular black 
band on the secondaries characteristic of the female; on the 
under surface also, which is more creamy in tint than in 
T. achine, this angular band is sometimes indicated in saffron- 
yellow. TT. fumidus (of which T. ramaquebana is the female) 
is merely a starved form of the subspecies. ‘The dry-season 
form is less strongly marked than in that phase of 7. achine, 
and is characterized by the usual rosy coloration on the under 
surface. Of our eighteen examples of this subspecies no less 
than sixteen were obtained in the Transvaal, nine of which 
were received in the Godman and Salvin collection. 
T. ramaquebana, curiously enough, is referred by Mr. Guy 
A. K. Marshall to the synonymy of his heterogeneous 
“ T. evagore,”’ one of the most singular combinations of dry- 
and wet-season forms, of species belonging to widely different 
sections of the genus, which have been associated together
