 pressed in the centre, the sides with broad white stripes ; legs

Natal. 



Although this pretty little species resembles Heterocliia Eaeu- 

 peri, Schm., in several respects, its narrower form, bidentate 

 anterior tibiae and differently formed thorax cause me to refer 

 it to that genus with considerable doubt, and as I have seeii but 

 a single male specimen, and know Raeuperi by description only, 

 I have not considered it advisable to estabhsh a neAv genus until 

 an opportunity occurs of examining more material.
