more elongate, and instead of squamose appressed hairs the intervals 

 on the elytra are filled with round bright yellow scales which form 

 also a narrow band on the apical margin ; the apical part of the pro- 

 pygidium and the pygidium are clothed with nearly contiguous, round, 

 thick, yellow scales, while only the edges of the abdominal segments 

 are scaly, and the scales are white ; hind legs as in Heterochelus 

 viiiiutiis, anterior tibi» with the fourth basal tooth strongly 

 developed. 



Female unknown . 



Length 4i-5 nnn. ; width 2-2f mm. 



Hab. Cape Colony (Namaqualand). 



HeTEROCHELUS (IsCHNOCHEIiUS) PR.ESTABILIS. 



Male : Very closely allied to H. snlcatus; the shape is similar 

 and also that of the anterior and posterior tibiae ; the elytra have 

 also each a juxta-sutural band of yellow or yellowish scales beginning 

 at a long distance from the base and rounding the apex, and another 

 dorsal one reaching from the base to the median part of the disk, and 

 the scutellum is also clothed with somewhat large, round scales, but 

 the prothorax is very finely and very closely scabroso-punctate, and 

 the median sulcus is less deep, especially in the anterior part. 



Female : Black, with the elytra testaceous, but slightly infuscate 

 at the base ; the punctures on the prothorax are not so closely set as 

 in the male, especially along the median groove, and on the elytra 

 the two discoidal bands of scales are longer, and there is also an 

 outer marginal one round reaching from the apex to humeral part. 



Length 4|-5 mm. ; width 2^ mm. 



Hah. Cape Colony (Willowmore). 



Hetekochelus (Ischnochelus) puerilis, n. spec. 

 Male : Black, with the elytra light testaceous, and the legs red; the 

 elytra are covered with small, seriate, not closely set, very short 

 appressed hairs, and only in the apical margin is there a narrow band 

 of scales, but the scutellum, the pygidial part, and the abdomen are 

 densely scaly ; clypeus a little attenuate laterally, quadri-dentate, 

 and with the lateral angular projection distinct ; prothorax closely 

 scabroso-punctate, clothed with a dense but short, erect greyish 

 pubescence, and having in the posterior part a somewhat broad but 

 very shallow longitudinal groove ; elytra not costulate, not very 

 sinuate laterally, and not much elongated ; hind legs simple, hind 

 tibiae not very robust, very slightly ampliated underneath before
