sternum impressed longitudinally, basal process of prosternum ovate ; 

 anterior tibiae with one intermediate and one supra-basal serrate 

 tooth ; inner claw of the male sinuate inwardly towards the tip, and 

 having there three short bristles. 



Length 19 mm. ; width 9-9|- mm. 



Hah. Mozambique (Louren90-Marquez). 



According to Herr H. Kolbe, H. corvinus is synonymous with 

 H. licas. 



Heteronychus indigus, n. spec. 



This species, of which the female only is known, and the habitat 

 uncertain, is not unlike the female of H. tuilmsi, but it is much 

 smaller, and the elytra are more ampliated laterally behind in pro- 

 portion to its size, the shape of the head and sculpture are 

 similar, but it is probable that in the male the posterior part of 

 the head is less rugose, as in H. wihnsi, the clypeal carina with 

 which the fontal one is merged is very broadly interrupted at middle, 

 much raised, and even slightly angular where interrupted ; the pro- 

 thorax is similar in shape and sculpture ; the elytra are more ampliate 

 past the lateral sinuation, the striae are equally deep, but the punc- 

 tures are not quite so well defined, only the seventh interval from 

 the suture showing a few punctures in the posterior part ; the striae 

 on the propygidium are very wide transversely, and are separated 

 towards the base by a triangular, nearly smooth space ; pygidium 

 with only a few lateral punctures, the rest of the surface being 

 smooth ; second basal abdominal segment with five setigerous punc- 

 tures, third and fourth with only two ; mestasternum and prosternum 

 normal; anterior tibiae with one intermediate and one basal serrate 

 tooth. 



Length 15 mm. ; width 8 mm. 



Hab. ? Natal. 



The shape of the stridulating striae on the propygidium will easily 

 lead to the identification of this otherwise obscure species. 



Heteronychus mashunus, n. spec, 

 Plate XL., fig. 4. 



Male : Shape, size, and sculpture of the female H. indigus, from 

 which it differs in the clypeal carina not being distinctly interrupted 

 in the centre, and in the frontal carina being somewhat distinct and 

 arcuate in the median part ; the striae on the elytra are similar, but 

 there is a row of not w^ell defined punctures in the posterior part of
