22 Descriptive Catalogue [1897. 



grooved for two-thirds of the length, with the edges dented slightly 

 by the intervals of four shallow striae occurring on both upper and 

 under sides of the outer declivity ; prothorax with the transverse 

 median impression reaching from side to side, and with a lateral 

 flavescent pubescence ; anterior part rounded laterally, narrowing 

 from base to apex and slightly emarginate in the centre, posterior 

 part bi-impressed in the centre and constricted laterally at base ; 

 elytra parallel, covered with closely set, briefly pubescent punctures; 

 tibiae slender. Length lOf mm. ; width 4J mm. 

 Hob. Transvaal (Eustenburg), Bechuanaland. 



P. MIMUS. 



The colour and shape of head and prothorax are as in P. damarinus, 

 but the shape of the antennal club is different ; it is not so thick in 

 the posterior part, the inner margin is sharper, nearly straight, the 

 emargination of the posterior part is not so pronounced, the grooved 

 part is deeper, and the striae better defined and indent more the 

 edges of the groove ; instead of being smooth and shining they are 

 very finely granulose, opaque, and glabrous ; the spur of the outer 

 angle is a little longer and less curved. 



The shape of the club is intermediate between that of P. damarinus 

 and P. dohmi, but it is not setose as in the latter, nor is the posterior 

 margin grooved from base to apex. Length 10 J mm. ; width 4 mm.

 Trans. Entom. Soc. Lond., 1852, p. 93; Thesaur. Entom. Oxon., 



p. 92, pi. xvii., fig. 12. 



Dark chestnut ; elytra covered with a very brief, closely set 

 pubescence ; head as in the two preceding species ; antennal club 

 longer than broad, thick, setulose, carinate in the anterior and apical 

 margins, the former very slightly sinuate above the base, posterior 

 part broadly grooved from end to end, and with a lateral yellow 

 pubescence ; posterior declivity with four broad striae on both sides, 

 the intervals of which indent the edges of the groove ; prothorax 

 shaped as in P. damarinus and P. mimus, but the anterior part is 

 more regularly rounded laterally. 



I have not seen this species, and the diagnosis here given is made 

 from the excellent figure given by Westwood in the "Thesaurus 

 Entomologicus Oxoniensis." The characters distinguishing this 

 species from P. damarinus and P. mimus are the broader and longer 

 groove in the posterior part of the club, and also the striae on both
