the base, which is narrower by one-third than the median part, faintly- 

 punctured, very shining ; elytra elongated, subparallel, narrowly 

 punctato-striate, with the intervals convex, hardly pubescent, outer 

 margin with a moderately thick pubescence. Length 19 mm. ; 

 width 7 mm. 



Hab. Transvaal (Maghalisberg, teste Bohem.). 



This handsome species is the only South African Chlcemus in 

 which the lateral ampliation of the prothorax is almost apical, 

 imparting to it, therefore, a very cordiform shape. 



I have seen Boheman's type — a male — only.

Head and prothorax coppery red; labrum, palpi, legs, and the 

 three basal joints of the antennae red, the other joints black ; head 

 and prothorax very closely punctured, the latter nearly as broad as 

 long, ampliated in the middle, and hardly broader at the base than 

 at the apex ; elytra elongato-ovate, not much broader at the base 

 than that of the prothorax, but a little ampliated laterally, punctato- 

 striate, with the intervals convex and shagreened, briej&y pubescent, 

 black, with a narrow yellow outer margin, and on each side above 

 the middle a transverse more or less sinuate yellow patch reaching 

 from the fourth interval to the outer margin, and a postical more or 

 less ovate spot extending from the fourth to the seventh stria a little 

 above the apical part ; under side piceous, iridescent. Length 17- 

 18 mm. ; width 7-7 J- mm. 



Hah. Upper Limpopo, also Senegambia. 



I have seen examples in which the anterior yellow patch of the 

 elytron has disappeared entirely or been reduced to a very small dot. 

 These examples were captured at the same time and in the same 

 spot as the normal form.

Head, prothorax, and elytra bottle-green, shining; labrum, antennae, 

 and legs yellowish red ; head smooth in the middle, punctulated all 

 round ; prothorax with the apical part narrower than the basal, 

 slightly ampliated in the middle, with the posterior lateral part 

 nearly straight, narrowly edged outwardly with yellow, and covered 

 with deep, irregular, closely-set punctures ; elytra subparallel, a little 

 broader at the base than the prothorax, narrowly punctato-striate, 

 with the intervals convex, but the suture as well as the three
