of the Genus 'Teracolus, Swarns. 467 
externally (7. subvenosus), but never connected with a black 
marginal line as in 7’. ¢sawra, or are merely dusky towards 
the tips (7. antevippe): the dry-season form (7. zera) has 
the under surface suffused with creamy pink, and is the least 
heavily marked type on the upper surface, 
Strictly speaking, the males of this species, without any 
trace of the blackish internal stripe on the upper surface 
(typical 7. antevippe), should perhaps be regarded as an 
intermediate phase between the wet- and dry-season forms, 
the wet form being represented by 7. subvenosus.

This may be regarded as the Southern representative of 
T. antevippe. It is much less heavily marked with black 
above, and, excepting in the male of the wet-season form 
(7. hero 8), is more or less densely irrorated with brown 
scales on the under surface; even in this form the internal 
streak of the primaries and costal streak of the secondaries 
are incomplete. ‘Two forms of all the phases occur, those of 
the wet and intermediate phases chiefly differing in size, 
having the under surface of the secondaries white, densely 
irrorated with brown; those of the dry-season form, how- 
ever, are less alike; the larger form (7. ¢gnifer =damarensis) 
has the under surface of the secondaries and apex of primaries 
rose-pink, finely irrorated with greyish brown in the males, 
somewhat more sandy in colouring, with the usual transverse 
banding in the females, the smaller form (7. cthonus=har- 
monides = Haevernickir) differing from the latter in the deeper 
more sandy colouring of the under surface, with coarse trans- 
verse striation rather than irroration. ‘The forms may be 
summarized as follows :— 
Wet-season. Intermediate. Dry. 
T. hero (large). Unnamed (large). T. ignifer (large).
