externally {T. stiltvenosus), but never connected with a black 

 marginal line as in T. isnura, or are merely dusky towards 

 the tips (7'. oTi/ei'i/ipe) : the dry-season torni {T. zcra) has 

 the under surface suH'used with creamy pink, and is the least 

 heavily marked type on the uj)per surface. 



fcftrictly speakins:, the males of this species, witliout any 

 trace of the blackish internal stripe on the Uj)per surface 

 (tyj)ical T. antevijipe), should perhaps be regardiid as an 

 intermediate phase between the wet- and dry-season forms, 

 the wet form being represented by T, suhvenosus.

This may be regarded as the Southern representative of 

 T. antevippe. It is much less heavily marked with black 

 above, and, cxcejjting in the male of the wct-scasou form 

 {T. hero ^), 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 ])hases occur, those of 

 the wet and intermediate phases chiefly differing in size, 

 liaving 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 [T. ignifer = damarensis) 

 has the itnder surface of the secondaries and apex of primaries 

 rose-pink, finely irrorated v.'ith greyish brown in the males, 

 somewhat more sandy in colouring, with the usual transverse 

 banding in the females, the smaller form {T. ithonus = har- 

 monides = IIaeverm'ckii) differing from the latter in the deeper 

 more sandy colouring ol the under surface, with coarse trans- 

 verse striation rather than irroration. The forms may be 

 summarized as follows : —
