second and third intervals on each side, outer sides and posterior 

 part faintly pubescent. Length 23-25 mm. ; width 7-8 mm. 



An intermediate form between P. semilevis und P. graphiiUeroicles ; 

 as much elongated as the former, and with the post-median white 

 macula on the elytra nearly alike ; the foveas are more closely and 

 regularly set and also more numerous ; the apical and lateral parts 

 are also distinctly pubescent. 



Hah. Ovampoland. 



De Chaudoir has described the species from some examples 

 captured in the Schimba Mountains, on the Zanzibar mainland. 



POLYHIRMA GRAPHIPTEROIDES, Guer., 



Eev. ZooL, 1845, p. 285. 

 P. S2tturata, Perr., Ann. Soc. Linn. Lyon, 1846, p. 43. 



Head with a greyish tomentum ; prothorax cordiform, as broad as 

 long, punctulate, broadly grooved in the centre, the groove with a 

 greyish white tomentum ; elytra distinctly ampliated from one-third 

 of the length, depressed with the anterior part more plane than 

 the interior, each one with three costae reaching from the base to 

 two-thirds of the length, with a double series of small alveolae in the 

 intervals, divided by a raised line nearly as much raised in the 

 first anterior third as the costae; posterior part substriate, with 

 evanescent punctures in the intervals, a sutural whitish band 

 reaching from the base to one-third of the length, and a sub- 

 transverse white patch situated at the apex of the costae and reaching 

 from the first costa to the inner part of the outer margin. Length 

 24-26 mm. ; width, 8-9 mm. 



Closely allied to P. perspicillaris ; the elytra are more ampliated at 

 a certain distance from the base and much broader ; the sutural band 

 is identical, but the two coalescing supra-apical spots of perspicillaris 

 are replaced by a broad subtransverse band consisting of three 

 coalescing patches.

POLYHIRMA BILUNATA, Boliem., 



Yet. Ac. Forh., 1860, p. 8. 



Head with a greyish tomentum ; prothorax elongato-cordate, one- 

 fifth longer than broad, with the usual median groove and the 

 pubescent longitudinal band, outer sides slightly tomentose ; elytra 

 slender, much elongated, depressed with the posterior part more 

 plane than the anterior, each one with the three costae and" intervals 

 as in P. grapliipteroides, but a little narrower ; the sutural band is the 

 same, but the supra-apical band is diagonal, narrow, and reaches on
