squamose ; elytra plainly tri-sulcate on each side with the sulci filled 

 with a band of contiguous scales, the raised intervals are deeply 

 punctate ; propygidium with a narrow band of sub-orange yellow 

 scales ; pygidium vertical, dark brown and without scales from the 

 base to the middle, closely scaly thence to the apex, sides of the 

 abdomen covered with sub-lanuginose scales ; pectus clothed with 

 hairs and scales ; hind femora greatly developed, clothed with sub- 

 appressed, moderately dense hairs ; the trochanters are produced 

 into a long and robust tooth, strongly sinuate in the inner part, the 

 apical outer part of the knee is simple, but the inner is provided with 

 a tooth as long as but more robust than the trochanterine spine, the 

 hind tibiae are not grooved, but they are deeply incised inwardly near 

 the knee with the lower part of the incision plainly dentate, the lower 

 edge is distinctly serrate, and the apical part is strongly mucronate 

 on each side, but the lower mucro is longer than the upper ; inner 

 hind claw half the size of the outer. 



This species is allied to H. vulpinus in the general appearance, 

 but the spines of the trochanters and the inner part of the knee of the 

 hind femora are much more developed ; the lower part of the inner 

 incision of the tibiae near the knee is very plainly dentate, and the 

 upper apical part much more strongly mucronate ; the vestiture of 

 the pygidium is different, and the pygidium itself is vertical instead 

 of being conspicuously swollen in the centre as in H. vulpinus ; it is 

 thus similar to that of H. multidentatus, from which species it differs 

 in several characters. Female unknown. 



Length 7 mm. ; width 4^ mm. 



Hab. Natal (Howick). 



This species is to follow H. vulpinus and H. lineatus, Cat. i., 

 p. 723. 



Heterochelus multidentatus, Burm., Catal. i., p. 724. 



Having obtained lately more examples of H. multidentatus, I find 

 that especially in the smaller development the pygidium has on each 

 side of the base a small, velvety, transverse, plainly discernible 

 patch. 



Female : Like the male in colour and vestiture, but the two black 

 patches on the pygidium are wider, and the four clypeal teeth very 

 obtuse. 



Hab. Cape Colony (Willowmore, Oudtshoorn). 



Heterochelus pavidus, n. spec. 



Dark greenish bronze with the elytra and legs chestnut-brown or 

 reddish ; clypeus with the two median teeth of the anterior margin
