Hah. N'Cuiini. 



Jet-black, .sliiiiin<r, the elytra ivory-wliite ; clypeiis slij^^htly einar}ri- 

 nate ; head tinely piinctiired ; prothorax inipunetate, \v.\-y tran.sver.se, 

 the anterior aiig-les not produced ; elytra broadly ovate, very little 

 longer than broad, dead ivory-white, obsoletely impressed, each with 

 three very distinct but slightly elevated costa), the two inner crowned 

 wdtli sharp, slender, distantly set teeth, the outer with a double row of 

 more closely set and shorter teeth ; body beneath and le;i3 l)lack ; the 

 abdomen and sterna finely coiTugated. Length 4^ lines. 



A remarkable species, very distinct from the other w^hite-win«;ed 

 members of the genus (Langei, canflidipcnnis, &c.) in the form of the 

 elytra and their toothed costal. It was taken by Mr. Anderson in 

 South Africa, somewhere north of Natal, and towards Lake N'Gami.

The clypeus being confounded with the front, nearly hiding the lip 

 and mandible, is a character at variance with the rest of the sub- 

 family. The fore tibia) are those oi Anomalipus (placed by Solier in 

 this group) ; the tarsi, closely ciliated on each side beneath, appear 

 in consequence canahculate. The granules with which the upper 

 parts are covered rise abruptly out of a greyish exudation, and are 

 very irregular in form and size.
