the posterior part, on the second, third, and last alveolas ; pro- 

 thorax with a median band ; elytra with a circa-scutellary patch 



and a broad postical one ; alveolae broad and fulvous algoensis. 



Elytra with six uninterrupted costse ; bands and patches as 

 in algoensis Plantei. 



Elytra elongated, parallel, not diagonally truncate behind. 



Elytra with six convex costse reaching from base to apex ; 

 intervals punctato-striate Alsfoni. 



POLYHIRMA SCROBICULATA, BertoL, 



Nov. Comm. Ac. Bonon., x., 1849, p. 410, pi. 9, fig. 3. 



Totally black ; head with a very short, sparse greyish tomentum ; 

 prothorax very long, narrow, swollen in the centre, closely punctured^ 

 with a faintly raised longitudinal line in the centre ; elytra much 

 elongated, hardly broader than the end of the prothorax at the base, 

 ampliated from the base, the outer sides from below the base nearly 

 straight, truncated obliquely behind, moderately convex in the 

 anterior part and very depressed behind, with seven sharp, con- 

 tinuous lines running from base to apex, and an outer one. running 

 from two-thirds of the length to the apex ; intervals very broadly 

 foveate, the fovege deeper in the anterior part, the posterior part 

 more raised, ending in a crescent-shaped wall, and less deep towards 

 the apex, without any reticulation ; no trace of any white patch or 

 tomentum. Length 19-20 mm. ; width 6-6J mm. 



Hab. Mozambique (Lourenco-Marquez, Kikatla, Gazaland). 



In the Delagoa Bay examples the reticulated alveolae are not so 

 deep in the posterior part as in one example, ex collect. Mnitzech 

 from Mozambique. 



POLYHIRMA GRACILIS, Dcj., 



Spec. Col., v., p. 468. 

 p. fossulata, Perr., Ann. Soc. Linn. Lyon, 1846, p. 50. 



Black ; head with a greyish tomentum ; prothorax elongate, 

 swollen in the anterior part, one-third longer than broad at the 

 widest part, broadly grooved in the centre, with the groove filled 

 with greyish tomentum and closely punctured ; elytra with a small 

 scutellary greyish patch, ampliated from the base, outer sides nearly 

 straight, truncated obliquely behind, moderately convex in the 

 anterior part and depressed in the apical one, each one with seven 

 acute costge and an outer one reaching from the median part to the 

 apex ; intervals deeply foveate from the base to past the middle, and 

 deeply punctured from there to the apex. 



Allied to P. scrohiculata, but the prothorax is less slender, the 

 elytra are less depressed behind, and the foveas are narrower, and 

 not so deep. Length 17-20 mm. ; width 5-6 mm.
