This belongs to the group of the European C labiata, 

 and is rather closely related to that species, but is not 

 very near any other Ethiopian species. The interantennal 

 carina is less elevated than in labiata, and is flattened to- 

 wards the base of the clypeus. Two females from IMlanje 

 Plateau, Nyasaland, 6500 ft. {S. A.Neave), December 191?, 

 have the postscutellum black and the lamina of the clypeus 

 niiicli reduced iu size. These may represent a subspecies, 

 but I cannot regard them as specifically distinct.

 presented to the South African Museum by the late Dr. I\1. 

 l(icono. They consist of a left tibia, a cervical vertebra, 

 and a portion of the left ilium. 



Left Tibia, — The tibia is 109 mm. long. Tlie proximal 

 articular .surtace is 31 mm. long and 18 mm. broad. This 

 surface for the most part slopes obliquely backwards and 

 laieially, the inner border being convex from front to back 

 and higher in front than behind. The tuberositas tibiaj is 

 almost the highest point of the bone; it is j)rolonged ante- 

 riorly and turned slightly outwards. The lateral condyle is
