348 Descriptive Catalogue [1896. 



moderately convex with the apical part depressed, shining, each one 

 with six acute costse somewhat wavy, reaching from the base to four- 

 fifths of the length, the inner costa near the suture beginning only 

 in the median part, intervals broadly foveate, a sutural white pubes- 

 cent band reaching from the base to where the inner costa begins 

 and a small triangular or diamond- shaped small white patch at the 

 apex of the suture. Length 22-26 mm. ; width 6-7^ mm. 



Hab. Zambezia (Victoria Falls, Salisbury, between Limpopo and 

 Zambeze Rivers, Buluwayo.) 



POLYHIRMA MACILENTA, OHvier, 



Ent., iii., 35, p. 26, pi. 11, fig. 130. 



P. foveata, Perr., I. c., p. 43. 



P. Dreget, Guer., Lefev. Voy. Abyss., p. 257. 



P. exarata, Bohem., Insect. Caffr., i., p. 109. 



Head with a greyish pubescence ; prothorax cordiform, closely 

 punctured, broadly grooved in the centre with a longitudinal white 

 band ; elytra elongated, nearly parallel, moderately convex, with the 

 apical part depressed, each with seven sharp slightly sinuose costae, 

 reaching from the base to three-fourths of the length, the sixth costa 

 very short and beginning at about two-thirds of the length of 

 the elytron and ending as far behind as the seventh intervals, 

 broadly alveolate, the bottom of the alveolae fulvous, a very short 

 basal sutural patch, and another, hardly broader, at the apex. Length 

 21-23 mm. ; width 6-7 mm. 



Hah. Orange Free State (Cronstad), Transvaal (Pretoria, Marico 

 Eustenburg), Zambezia (Buluwayo). 



In female examples the sixth costa is a little longer than in the 

 male. 



There can be but little doubt about the identity of P. macilcnta. 

 with P. foveata ; Olivier saw, in all probability, an example with the 

 white pubescence rubbed off, which is not a rare occiu-rence.

 white band ; elytra subparallel, moderately convex, with the apical 

 part much depressed, each with seven costaB reaching from the base 

 to a little past the middle, with the sixth one situated behind and 

 extremely short, intervals with broad fovei^ without any fulvous
