 strigose, and pubescent, with a large mark on each side united 

 at the base and several small spots in the centre white. 



Beneath shining black, strigose and with dense long ashy 

 pubescence at the sides ; mesosternal process very short, dilated 

 and ti-uncate at the apex ; abdomen deeply longitudinally im- 

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

Natal. 



Although this pretty little species resembles Heteroclita Raeu- 

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

 anterior tibiaj and differently formed thorax cause me to refer 

 it to that genus with considerable doubt, and as I have seen Ijut 

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

 I have not considered it advisable to establish a new genus until 

 an opportunity occurs of examining more material.
