1892.] of the Colecptera of South Africa. 13 



of which Thomson's figare gives a good idea, seems to be restricted to 

 Northern Damaraland and Ovampoland. 



The examples from the Limpopo region and the Transvaal, also from 

 British Bechuanaland, are less ampliated in the centre (IG""*™' across the 

 shoulders, 2l°'*'"' in the middle, and IQ'"'"^* at the declivity), while other 

 specimens from British Bechuana'and, Transvaal (Potchefstroom) and 

 the Orange Free State, are hardly broader in the middle than a good 

 size tuherculata (14™*™* at the shoulders, 18 in the middle, and 16 at the 

 declivity), from which they are to be distinguished less by the shape 

 than by the finer granulation. 



I believe that it is fiom one of these small examples that De Castlenau 

 has described if. Ludovici, length, 82™*™', width, 16-J™*™* I cannot, 



however, consider it as a variety. 



Var. DAMAEENSIS. 



Black, shining ; head and protho'ax like the type form ; elytra more 

 regularly cordiform, that is to say less narrowed at the base, with the 

 whole of the disk from the outer sides gradually convex and sloping 

 gradually behind, the sides are loosely granulated, and the sutural part 

 nearly smooth, the outer margins are serrated as in the type. 



The convex shape of the upper part of the elytra, which are also 

 rounder laterally is the distinguishing feature of this variety. I have 

 received a small example from Lower Damaraland, almost smooth, 

 shining, and with the elytra nearly as sub-orbicular as M. ferox, and 

 which, except for the differently shaped jaws, might have been taken 

 for a variety of the latter.
