496 Dr. A. G. Butler—A Revision 
In its wet-season form this is the most heavily marked of 
all the crimson-tipped Zeracol’. This form is the typical 
one, and was named by me as 1’. cinerascens in consequence 
of Pastor Wallengren’s error in describing it as a Thestias ; 
T. Wallengrent=confusa is the dry-season form; an inter- 
mediate form also occurs.

This very distinct butterfly was obtained by Mr. J. J. : 
Walker, R.N., about the year 1883. This ardent collector 4 
and enthusiastic entomologist appears only to have been 4 
able to secure dry and intermediate phases of the species. q 
T. Walkeri is, in some respects, intermediate in character 
between 7’. Anne and 7’. pseudacaste, the primaries of the 
male above somewhat resembling the wet-season form of i 
T. Anne, but the secondaries, from their less heavily spotted 2 
border, perhaps approaching nearer to 7’. pseudacaste ; on the 
whole, however, 7’. Walker? is far nearer to 7. Hildebrandti 2 
and Anne than to 7’. pseudacaste and eupompe. %

Ranges from the White Nile and Abyssinia southwards to

My three supposed species were all based upon wet-season 
examples, 7’. pseudacaste being based upon examples obtained 
on the White Nile probably just after the rainy season, the 
male lightly but the female heavily marked with black above. 
T. phenius and 1’. miles are both typical wet-season forms, | 
the former being more heavily marked with black on both ~— 
surfaces than the latter and showing less crimson in the apical , 
patch, the lowest spot of which is extremely small. The 
black veining below is sometimes very heavy, especially in 
females of the wet-season phase, but in the intermediate 
phase it almost disappears, though in this species the <" 5 of 
the veins are always blackened in all the phases. 
Although the wet-season form of this butterfly and of the 
allied 7’. eupompe appear to occur together to the north of 
their range, they differ so markedly in all their phases that I
