the posterior half nearly plane, each one with six costse, the three 

 inner ones reaching the median part, the other three longer, intervals 

 with broad fovege, posterior part smooth, no pubescent patch or

 Hah. Bechuanaland. 



POLYHIRMA AMATONGA, Per., 



Trans. S. Afric. Phil. Soc, 1892, p. 102. 



Head without any pubescence ; prothorax a little longer than 

 broad, subelongato-cordate, broadly grooved in the centre, the groove 

 hairless ; elytra oblong, a little more convex in the male than in the 

 female, depressed behind, the male with six acute costaB on each 

 side, the fourth one interrupted at about the median part and having 

 only an apical rudiment, the cost^ entire in the female, the intervals 

 alveolate, with a fulvous pubescence in the bottom of each alveola, 

 costse reaching from the base to two-thirds of the length. Length 

 24-28 mm. ; width 7^-8^ mm. 



Hah. Tongaland, Delagoa Bay (Eikatla). 



In the original description of this species I gave a wrong diagnosis 

 of the male, having mistaken for such a very small example of P. 

 Plantei, with prothorax narrower than usual. 



POLYHIEMA CONSOBRINA. 



Shape, size, and colouring of P. amatonga ; the sculpture of the 

 head and prothorax is alike ; the elytra are as broadly foveate and 

 the alveolae have the fulvous pubescence, but in both sexes the six 

 costae on each side are entire, and they also reach further down, from 

 the base to three-fourths of the length, thus reducing the size of the 

 apical smooth part. Length 24-28 mm. ; width 7-|-9 mm. 



Hah. Transvaal (Middelburg) . 



POLYHIEMA BOUCARDI, Chaud., 



Coleopt. Novit., 1883, p. 27. 

 P. seijtemcostata, Dohrn, Stett. Ent. Zeit., 1883, p. 357. 



Head with a greyish very sparse pubescence ; prothorax cordi- 

 form, as broad as long, or very nearly so, closely punctured, broadly 

 grooved in the centre, with a more or less defined pubescent median 

 greyish band ; elytra nearly parallel in the male, gradually ampli- 

 ated from one-third of the length, with the outer sides not 

 rounded behind in the female, plane, each one with seven costae 

 reaching from the base to four-fifths of the length, intervals alveolate, 

 outer and posterior margins faintly pubescent, a small, greyish white, 

 short, sutural patch at the base. Length 29-33 mm. ; width 9-11 mm.
