tliere is a faint trace of a smooth longitudinal median line reaching 

 from apex to base ; elytra very little broader than the prothorax at 

 l)ase, and a little ampliated laterally from the base to a shoi't distance 

 fi'om the apex where they are one-fifth broader than the prothorax at 

 its widest part, convex, finely striate, the strige punctate at intervals of 

 about 1 mm., and the intervals filled with equi-distant foveolate punc- 

 tures moderately closely set and interspersed with minute shining 

 granules ; along the base • there is a distinct but minute tubercle in 

 each interval ; pygidium sub-semicircular, flat, sharply carinate, and 

 very slightly recurved at apex ; in the male it is produced underneath 

 in an elliptical process fitting in the deeply emarginate last abdo- 

 minal segment and is covered with equi-distant and moderately closely 

 set foveolate punctures, but in the female the apical margin of the 

 pygidium is not at all recurved, nor is it produced underneath against 

 the last abdominal segment which is not emarginate ; the sculpture 

 is the same as that of the male, but there are very often two small 

 flattened tu])ercles set close together at about the median part ; 

 imder side glabrous, foveolato-punctate ; metasternum deeply im- 

 pressed at the base, and less deeply so between the inter- 

 mediate coxa? ; these two impressions are united by a longitudinal 

 line. 



Length 21-26 mm. ; width 15-18 mm. 



This species has a very wide range in South Africa, and reaches 

 as far as Mpapwa in German East Africa. It is very closely allied 

 to C. ciLin-eus, Fabr., from the West Coast of Africa, but the pygidium 

 of the male is not so sharply aculeate and recurved at tip, and the 

 elytra are more rounded. 



Hah. Cape Colony (East London, Kimberley), Natal (Durban, 

 Frere, Maritzburg), Transvaal (whole country), Bechuanaland (Kuru- 

 man), Lower Ehodesia (Salisbury, Buluwayo, Mazoe, Victoria Falls, 

 Manica, Salisbury), Damaraland, Ovampoland. 



Anachalcos spectabilis, n. spec. 



Colour, shape, and sculpture of A. convcxus, but less convex and 

 more elongate. The difference between the two species consists in 

 the shape of the pygidium. In A. convcxua the pygidium is broadly 

 rounded at apex and uniformly carinate all round, whereas in 

 A. spectahilis the pygidium is sharply triangular, and the margin 

 is very distinctly recurved at the apex ; it is slightly impressed in 

 the centre and closely foveolato-punctate. 



Length 31 mm. ; width 18 mm. 



Hah. Southern Rhodesia (Mazoe).
