Brak Kloof. Mrs. G. White. 



A broad insect. Front and vertex densely covered with 

 longish grey pubescence ; the sides of the face more densely with 

 woolly hair of a brighter, white colour. Front margined above 

 by a stout, waved transverse keel ; its centre with a Ijroad, fiat, 

 smooth longtitudinal furrow ; the sides pui\ctured, more strongly 

 above than below. Face finely closely punctured ; there is a 

 smooth space below each antenna. Mandibles dark violet, green 

 at the base. Temples wide, longei* than the 4th antennal joint, 

 roundly, but not much narrowed ; the occiput is almost transverse. 

 The temples are keeled on the innerside, the keel becoming stouter 

 below, and continued down the outerside of the malar space. 

 Pronotum more than half the length of the mesonotum. The 

 central part of the metanotum is bordered by wide deep oblique 

 furrows, jjurple in colour ; they end in two deep, larger, longer 

 than wide, foveae. The punctuation on the head and thorax is 

 coarser ; on the pleura? it forms reticulations ; below the middle 

 there is a smooth space with 4 narrow vertical keels, of 

 which the posterior is the smaller. Tarsi black. Legs covered 

 with white pubescence. The 1st abdominal segment is more 

 strongly and deeply punctured (especially in the middle) than the 

 2nd : the lattei- is keeled to shortly beyond the middle. The 

 apical teeth are shoit, sharp, the central incision is shoiter than 

 the lateral, thn foveae are large, mostly wider than long. The 

 latei-al angles of the metanotum are large, triangular, sharply 

 pointed : on the apex of ':he metapleurse below is a large, deep 

 depression, longer than wide, counting from above down- 

 wards.
