Nov. Comm. Ac. Bohon., x., 1849, p. 386, pi. 8, fig. 2 ; 



Klug, Peters' Eeise, 1862, p. 153, pi. 8, fig. 7. 



Head with a greyish pubescence ; prothorax one-fifth longer than 

 broad, cordate, closely punctured, deeply grooved in the centre with 

 a narrow yellowish white longitudinal median band ; elytra nearly 

 parallel in the male, more elongato-ovate in the female, each one 

 with seven costse, only reaching from the base to four-fifths of the 

 length, the sixth costa is only a very short supra-apical one, intervals 

 alveolate, a short sutural greyish white basal band, the posterior 

 denuded part and the outer margins clothed with a dense, greyish, 

 very short pubescence. Length 31 mm. ; width 9|- mm. 



Hah. Zambezia (Manica). 



PoLYHiRMA ALVEOLATA, Breme, 

 Ann. Soc. Ent. France, 1844, p. 293, pi. 7, fig. 5. 



Head with hardly any pubescence ; prothorax very depressed, 

 broad, almost hexagonal in the male, more cordate in the female, 

 closely punctured, very broadly depressed longitudinally in the 

 centre and with a very fine groove in the depression, no median 

 pubescent band ; elytra nearly parallel in the male, and very 

 slightly ampliated past the middle in the female, depressed, each 

 one with six costse reaching from the base to a very short distance 

 from the apex, with the exception of the fifth one at the base, which 

 is very short, reaching only one-sixth of the length, intervals broadly 

 alveolate, bottom of alveolae with a fulvous pubescence. Length 

 31-33 mm. ; width 9-10 mm. 



Hah. Cape Colony (Vaal Eiver), Orange Free State (Kroonstad), 

 Transvaal (Rustenburg, Marico, Pretoria). 



In all the examples of this species which I have seen, and there 

 are a great many, the absence of greyish pubescence or greyish 

 bands on thorax or elytra has always been constant. 



POLYHIKMA ALGOENSIS. 



Shape and size of P. alveolata, but the head is very pubescent ; 

 the prothorax, shaped as in the previous species in both sexes, has a 

 very broad yellowish white pubescent band ; in the elytra the costse 

 reach four-fifths of the length, the basal part of the sixth one is 

 longer, and there is also a trace of it in the apical part, the outer 

 margin is densely pubescent, and so is the smooth apical part of each 

 elytron. Length 30-34 mm. ; width 9-11 mm.
