274 RHOPALOCERA AFRIC.E AUSTRALIS. 



with a most irregular, very sharply dentated, inore or less 

 suffused transverse stripe immediately succeeding it ; a small 

 spot touching costal nervure about middle ; a submarginal 

 dentate streak, often indistinct, always so towards costa. In 

 both veings traces occasionally of a hind-marginal row of spots 

 sometimes interiorly bordered by some whitish marks. Cilia 

 blackish, interrupted with white between uervules. 



? . Orange usually rather paler and duller, border not so 

 dark ; ochreons basal suffusion usually much broader. Fore" 

 wing: at outer and upper edge of orange there is often an 

 upward projection of that colour ; border often very broad 

 at anal angle. Hind-ivmg : apical border usually broader 

 than in $ . Under-side. — As in $ . 



This species is very variable, chiefly in the colour of under-side of 

 hind-wing and the distinctness of its markings, but also in the extent and 

 tint of the orange of upper-sirle, which in some specimens is very limited 

 in extent, in others very broad. I have no doubt, of this being the true 

 Thyra of Linne, having taken one specimen near Cape Town whicli answers 

 in every particular to the details given in '* Museum Ludovicse, &c." In 

 the majority of examples the under-side markings are not so bright as Linn6 

 notes them, and the orange of upper-side is more thoroughly one unbroken 

 field. The Thyra of Godart seems to be a different species, comina: nearer 

 to Z. Perion than to any other. Some interesting specimens from Kaffraria 

 show a striking resemblance, except for the chequered cilia and want of 

 anal-angular point, to Z. Pier us. Cram., var, Aranda, Wallgr,), but the 

 under-surface is quite as usual. 



Pathways and bare spots on hill-sides.

Common. Has a short, swift, flight, and abruptly settles on the ground 

 or on stones. At Knysna I once or twice saw it on flowers of Brvjda.
