Show 1899.] PHYTOPHAGOUS COLEOPTERA OF AFRICA. 369 Hab. Salisbury, Mashonaland, Estcourt, Natal (67. Marshall). Of the specimen which I consider a Arariety and Avhich was obtained at Natal, I have only a single example before m e ; structurally it does not seem to differ from the type, but it diverges entirely in coloration. The whole under surface is black, the head has two bright fulvous spots at the vertex, the thorax is piceous, narrowly margined with fulvous, and the elytra show the same colour at the base and the apex. Possibly the specimen represents another species. HEMIXANTHA TERMINATA, sp. n. (Plate XXI. fig. 6.)
