518 Descriptive Catalogue [1896. 



narrowly striate with the intervals costate ; the costse are smooth 

 on the ridge, but have a regular series of moderately deep, closely-set 

 punctures on each side ; under side piceous, slightly iridescent. 

 Length 11-12^ mm. ; width 4-5 mm. 



Hah. Cape (Peddie), Natal (Frere, Newcastle, Escourt). 



Although Boheman's type of this species seems to have been lost, 

 there is, I think, hardly any doubt that the insect described by me 

 under that name, and which agrees very well with the description 

 is the same as the original one. 



Chl^enius natalensis, Chaud., 

 Monogr., loc. cit., p. 164. 



Colour, shape, and size of C. rufipes, with the elytra nearly as 

 parallel laterally ; the prothorax however is quite smooth instead of 

 being closely punctured ; the elytra are narrowly punctato-striate 

 with the intervals raised and smooth, with the exception of the two 

 outer ones which are punctulated. 



In some examples from Port Elizabeth the prothorax instead of 

 being quite smooth has a few shallow, distant punctures along the 

 edge of the outer margins, and a few deeper, irregular ones in the 

 base. Length 12-13 mm. ; width 5-5|- mm. 



Hah. Cape (Grahamstown, Port Elizabeth). 



Chl^nius aculeatus. 



Black, shining on the upper side ; palpi, antennae, and legs 

 piceous ; under side black, slightly iridescent ; head and prothorax 

 quite smooth, the latter trapezoid as in C. natalensis ; elytra fitting 

 against the prothorax, broadest at the base and narrowing gradually 

 towards the apex, striate with the intervals very slightly convex 

 and smooth. 



Easily distinguished by its small size and the aculeate shape of 

 the elytra posteriorly. Length 7 mm. ; w^idth 2^ mm. 



Hah, Cape Colony (King William's Town). 



Chl^nius Cham, Chaud., 



Plate X., fig. 4. 

 Monogr., loc. cit., p. 169. 



Black, shining on the upper side ; slightly iridescent underneath : 

 apical part of the last joint of the palpi and antennse with the 

 exception of the three basal joints which, like the legs, are black 

 or piceous, slightly rufescent ; head nearly smooth ; prothorax sub- 

 trapeziform but slightly incurved above the basal angle, plane on the 

 disk, but slightly sloping in the anterior part, smooth and without
