80 WILLOW BEETLE. 



by a deeply impressed central line; in the male the 

 antennae are half as long again as the body, in the 

 female scarcely longer than the body. The thorax is 

 slightly impressed and constricted in front and behind, 

 coarsely rugose, and with an obtuse tubercle on each 

 side behind the middle. The scutellum is rounded 

 behind and impressed at the base and in the centre. 

 The elytra are very closely and irregularly punctured ; 

 at the base the punctures are very coarse, deep, and 

 confluent, towards the apex they become smaller and 

 shallower, the shoulders are prominent and obtuse. 

 The under side and legs are coriaceous, and the tarsi 

 are very broad; in the male the anterior and middle 

 tibiae are slightly curved, and the anterior tarsi are 

 fringed with long black hairs. The length of the body 

 is 2035 millm. 



This beautiful but common South African " Long- 

 horn " varies very much in size, the bands on the elytra 

 vary a little in width, and in colour from pink to 

 vermilion : these varieties have been named and re- 

 named several times by different writers. In the typical 

 bicincta the apical marginal band of the elytra is absent ; 

 in some specimens this is only represented by a small 

 spot, and in others it extends along the side margin and 

 joins the second transverse band. The figure is taken 

 from a large male example which, from a comparison 

 with the actual type, is found to agree precisely with 

 sumptuosa, and is also very similar to the variety 

 described and figured by Herbst under the name of 

 orientalis. 



Ceroplesis thunbergii of the ' Coleoptera Caffrariae ' is 

 evidently described from small and very fresh specimens 

 of this species, in which the thorax, base of the elytra, 

 and the under side have a red tomentose clothing ; this 

 tomentum is usually present on the thorax, but many 

 apparently worn specimens are quite destitute of it. In 

 these specimens the elytra generally have a more metallic 

 or greenish lustre. 0. E. J.
