 the sixth to the ninth joint dilated, the eighth with a flattened

lu spite of the great resemblance of this species to J\[. 

 siUnralis, Baly, and M. hipundata, Jac, I cannot identify it 

 with either of them, as the thorax is c^uite differently 

 sculptured and punctured in both sexes, and the head is 

 black. In the first-named species the thorax is strongly 

 punctured and shining and without the triangular groove. 

 M. hipunctata has a fulvous head and differently-punctured 

 thorax. The thorax in the female has the depression 

 very deep, bounded at the sides by strongly-raised ridges 

 of perfectly triangular shape, and there are also some raised 

 feeble smooth lines visible at each side ; the elytral spot in 

 the specimen before me is just indicated and the suture 

 in both sexes has the usual ridge at the posterior portion. 



Mcgalognatha natalcnsis, sp. n. 



Head, antennfe and the breast black, thorax pale fulvous, strongly 

 punctured, deeply transversely sulcate anteriorly ; elytra Havous, 

 finely and closely punctured, strongly depressed below the base. 



Length 6 millim. 



Fern. Head black, impunctate, antenmi3 with the apical joints 

 widened, the third and fourth joints more slender, equal ; thorax 

 subquadrate, naiTOwed at the base, the surface strongly and deeply 

 punctured, deeply transversely sulcate anteriorly and to a less 

 extent near the base, the anterior edge of the anterior sulcus strongly 

 raised, scutellum piceous and pubescent at the base ; elytra rather 

 deeply depressed below the base, very finely and closely punctured, 

 legs obscure testaceous, stained with fuscous and pubescent, abdomen 

 flavous. 



Rah. Frere, Natal. 



Of this species I only know a single female specimen, 

 like 31. melanocephala the head is black, but the thorax 

 has no tubercles, is less strongly punctured, and altogether
