female, costae alike, and the yellow hairs in the intervals and outer 

 margin, also the setigerous punctures on the sides of the costae, 

 identical. Length 50-57 mm. ; width 16-19 mm. 



Hah. Seems restricted to British Bechuanaland and N'Gami 

 or Ovampoland (Okovango River).

Head quadri-impressed between the eyes and with a very deep 

 transverse impression on the vertex ; labrum not incised laterally ; 

 prothorax of the male truncate at the apex, with the anterior angles 

 projecting, the anterior outer sides depressed, and the median part 

 of the disk produced into an excavated process overlapping the 

 elytra, deeply notched in the centre, and each lobe arcuated at the 

 apex ; prothorax of the female like that of the male in the anterior 

 part, but the median part of the disk is deeply excavated and raised 

 on each side, and produced behind in two short truncated lobes 

 divided by a small notch and hardly projecting beyond the base ; 

 elytra broad and very convex at the base in the male, narrower in 

 the female and with the humeral angles less pronounced, gradually 

 sloping behind, more broadly ovate in the female than in the male, 

 very slightly punctato-striate, or smooth with the intervals hardly 

 convex, black, subopaque, without any lateral white margin. Length 

 31-44 mm. ; width 12-16 mm. 



Hab. Cape Colony (Fraserburg, Namaqualand minor. Willow- 

 more, Calvinia, Worcester, Carnarvon, De Aar, Orange River), 

 Bechuanaland, Transvaal (? Leydenburg). 



Anthia algoa. 



Shape and colour of A. maxillosa ; the head and prothorax of each 

 sex are alike in both species, but the elytra are generally more 

 elongated and more parallel, flatter, very distinctly striated, with the 

 intervals moderately raised, and with a series of shallow setigerous 

 punctures on each side. 



I have not yet met with any form of transition between luaxillosa 

 and the present species, which, so far, seems to be restricted to 

 Mozambique (Rikatla). Length 46-51 mm. ; width 16-19 mm.
