262 RHOPALOCEEA AFRICA AUSTRALIS. 



from North Africa. While some of the species, such as 

 Zeuxo, Chrysaor, Sec, show a decided affinity to Chryso- 

 phanus, others, by their robust bodies and dull colouring, 

 seem to approach the Hesperidce. Thero, Thyra, and Pierus 

 have the antennae very gradually thickened, but in the more 

 metallic species the club, though gradually formed, is distinct. 

 In Protumnus (rather a doubtful member of this Genus), the 

 antennas are remarkably short and stout. All the species 

 have the vv^ings coloured above v^ith some shade of red or 

 orange, with dark borders and (usually) spots : in Thero, 

 however, the ground is brown and the spots orange. There 

 is great uniformity in the arrangement of the spots, especially 

 on the under-side, species spotless above presenting (except 

 Alphceus) the generic pattern beneath, with metallic or 

 bright-white centres to the spots of fore-wing, and numerous 

 metallic dots and markings on hind-wing. The borders of 

 fore-wing and the ground of hind-wing on under-side are 

 invariably of the same hue, usually of some shade of ochre, 

 which, in several species, is often replaced by a rich vinous 

 or lake tint. 



The metallic-coloured species have much the same habits 

 and flight as Chrysophanus, but the duller and heavier-made 

 fly very like Hesperidce, and continually settle on the bare 

 ground.

Metallic golden-orange, with a slight basal fuscous suffusion, 

 and spotted with black : a hind-marginal blackish border, 

 broad and even in fore-wing, narrow and dentated in hind- 

 wing. Fore-wing : a small spot in cell ; an elongate spot 

 closing cell, with a small costal spot a little above and beyond 

 it ; an irregular discal transverse row of seven spots, of which 

 the first three are usually confluent, and the two last (just 

 above submedian nervure) rarely so : costa slightly fuscous- 

 clouded ; usually a dot before middle below cell. Hind-wing :
