infuscate behind, very rugose, and have similar appressed sub- 

 squamiform hairs turning to yellow scales on the apical margin ; 

 propygidium and pygidium clothed with dense sub-lanuginose 

 scales. 



Length 6 mm. ; width 3 mm. 



Hab. Cape Colony (Carnarvon). 



Hetekochelus (Ischnochelus) bipartitus. Burns., 

 Handb. d. Entomol., iv., 1, 1884, p. 130. 



Male : Black, shining, elytra and scutellum clothed with dense, 

 contiguous, ovate yellow scales, prothorax with a narrow but very 

 distinct basal band of similar scales, edge of propygidium, pygidium, 

 and abdomen densely scaly, the scales yellow, intermediate and hind 

 legs reddish ; head rugose, hardly pubescent, clypeus slightly 

 narrowed laterally, slightly bi-dentate in the centre at the apex and 

 with the outer angles strongly reflexed ; prothorax nearly glabrous 

 except for the narrow basal line of yellow scales which, in well- 

 preserved examples, is continued on the outer margins, it is closely 

 scabroso-punctate in the anterior part, but simply punctate towards 

 the basal part, and the longitudinal median furrow is very deep ; 

 elytra not costulate, and entirely covered with the scales which are 

 comparatively large ; basal tooth of anterior tibiae broad and trian- 

 gular, but not as long as the one preceding it ; hind tibiae as in the 

 other species. 



Female : Like the male ; the scales are similar and equally dense ; 

 the pygidium is more convex and this character is the only one that 

 denotes the sex. 



Length 5^-6 mm. ; width 3 mm. 



Hab. Cape Colony (Namaqualand). 



Heterochelus (Ischnochelus) emeritus, n. spec. 



Male : Black, shining, with the elytra having a basal light testa- 

 ceous patch in the shape of a truncate cone reaching from each 

 humeral angle to about the median part ; legs reddish, head rugose 

 not very briefly pubescent, clypeus slightly narrowed laterally and 

 with the outer angles broadly and strongly reflexed and the anterior 

 part emarginate ; prothorax with the same sculpture as the preceding 

 species but more densely pubescent, the pubescence being black and 

 erect, there is no trace of scale or squamose hairs ; scutellum partly 

 clothed with whitish squamose appressed hairs ; elytra elongate, 

 narrowed laterally towards the apex, not costulate, punctured but
