J . Paler, duller. Fore-wing : orange spot near apex dis- 

 tinct, elongate-lunular, and united to central orange space by two 

 similar lunular marks below it. Hind-wing: orange band very 

 slightly dentate on either edge. Underside in every respect like 

 that of S • 



The relations of this species to others of the genus are very 

 curious and interesting. Its colouring and underside markings 

 give it considerable resemblance to Z. Thyra, Linn., from which 

 it is at once distinguished by the broad, conspicuous cilia, 

 the narrowness of the orange in hind-wing, and the different 

 arrangement and far greater brilliancy of the whitish-silvery 

 under-surface markings. In structure, however, it differs widely 

 from Thyra, — the palpi being stouter, blunter, more porrect, the 

 antennae shorter, more gradually incrassate, the thorax less robust, 

 the fore-wings less acute, and the hind-wings without any elonga- 

 tion in anal-angular region, indeed the abdomen is very nearly 

 (in the ? within \ lin.) as long as inner margin. The last cha- 

 racter, as well as the roundness of the wings and broad cilia, 

 indicate some affinity with Z. Protumnus, Linn., while the others 

 are nearly those presented by Z. Thero, Linn., which is totally 

 different in form of wings. The antennae coincide more closely 

 with those of Z. Pierus and Z. Mars than of other species. 



I discovered this very distinct and handsome species in March, 

 1860, on the hills near Cape Town. I at first took it for a finely- 

 marked Thyra, as it pitched on the ground and on stones. It is 

 extremely local, but common in its favourite haunts ; and is 

 often to be taken with the fingers, never flying more than a few 

 yards when roused.

$ . Dull ochreous-brown. Fore-wing : an orange mark on 

 costa at base. Hind-wing : much darker than fore-wing, espe- 

 cially at anal angle, and clothed with orange hairs except near 

 costa and hind-margin ; cilia orange from anal angle for more 

 than half the extent of hind-margin, fading thence into greyish. 

 Underside. — Tinged with bronzed-green. Fore-wing : on inner- 

 margin, about middle, a dull-whitish space. Hind-wing: before
