surface. Abdomen elongate, much compressed laterally, not 

 so long as inner margin of hind-wings, clothed with silky 

 pubesence at its base. 



This Genus contains three South African species — all fine 

 insects, though very different in appearance. E. Biiquetii is 

 greenish-white ; E. Cleodora is white with black borders ; 

 while E. Leda is sulphur-yellow with orange tips to the fore- 

 wings. I have personal acquaintance with only one of these, 

 E. Buquetii; but I have no doubt that its habits are those 

 of others of the Genus. Its flight is singularly swift, though 

 very irregular, and it appears to keep very constantly to the 

 woods. All three species are rather above the middle size, 

 none expanding under 2 inches 2 lines, and E. Leda attaining 

 an expanse of 2| inches.

$ . Bright sulphur-yellow ; with hroad, apical, orange 

 blotch on fore-wings. Fore-wing : orange at apex extending 

 inwardly to extremity of discoidal cell, and commencing on 

 costa above cell a little before its extremity — on hind-margin 

 reaching to third median nervule ; apex edged with ferru- 

 ginous-brown. Hind-wing : spotless ; slightly paler on 

 inner-margin. Under-side. — Fore-iving : sulphur-yellow ; 

 paler on inner-margin ; apical portion rich chrome-yellow, 

 containing, close to apex, two or three ferruginous spots with 

 large, silvery centres ; a very small, blackish, disco-cellular 

 dot. Hind-ioing : the same rich yellow as apex o^ fore-wing, 

 sometim.es slightly deeper in tint ; thickly flecked with ferru- 

 ginous, or ferruginous-brown ; a row of rather darker spots 

 along costal edge (which is fringed with pinkish hairs), the 

 largest and most conspicuous spot being an elongate one, 

 variable in shape, a little beyond middle, touching first sub- 

 costal nervule. 



S . Yellow paler than in $ . Fore-wing : the orange 

 apical patch less distinct, sometimes almost wholly obsolete ; 

 apex and upper half of hind-margin edged with ferruginous- 

 brown, which is not so clearly defined as in ^ ; a little 

 within hind-margin, and parallel to it, a row of five ferru- 

 ginous-brown spots between nervules, the lowest spot 

 indistinct, between second and third median nervules. 

 Hind-wing : spotless. Underside. — Forewing : pale lemon- 

 yellow ; beyond discoidal cell orange, deepening into ferru- 

 ginous-red at apex ; a minute disco-cellular spot ; spots at
