straight, feebly divergent towards the hind margin, which they do 

 not reach by a short distance, distinctly cut by the sulci; lateral 

 lobes rugulose. Prosternal tubercle distinctly widened and emar- 

 ginate aiDically. Elytra not reaching the hind knees. Last tergite 

 with a small tooth in the middle of the hind margin. Supra-anal 

 plate much the same as in P. granulatus. Cerci with the ajiical 

 part distinctly widened towards the obliquely truncate apex. 



General coloration brownish-grey (very much bleached by spirit). 

 Pronotum with the metazona darker than the prozona; the latter 

 with a median fascia, constricted before the middle. Elytra with 

 indefinite grey spots. Hind femora with two brown fasciae on the 

 uppersidc ; the inner side greyish-pale (probably bleached) ; a 

 blackish narrow ring at the knee- base. Hind tibiae pale. 



Length of body (somewhat contracted) 17-5 mm.; of pronotum 

 5-5 mm. ; of elytra 12 mm. ; of hind femora 12 mm.

 Africa {Gregory Coll.), 1 i^ (iype)- 



This species is easily separated from P. granulatus by 

 the shape and sculpture of pronotum, the shape of the 

 prosternal tubercle and cerci.

There is no reason whatever to regard C. iliepidus as 

 conspecific with C. crassus Walk., they being not congeneric 

 even ; thus, Kirby is wrong in putting iliepidus and pinguis 

 (which really are conspecific with each other) as synonyms 

 of crassus ; he has been evidently misled by the somewhat 

 similar coloration of hind femora in both these species. His 

 definition of Walker's types of iUejndus and pinguis in the 

 British Museum collection is also somewhat dubious : 

 Walker quotes two specimens ((^ and $) of iliepidus, both 

 from Natal, collected by M. Gueinzius, and only one of 

 the specimens labelled by Kirby, as Walker's type, is a 

 female from Gueinzius' collection, while another specimen 

 is not a male, but also a female, from A. Smith's collection,
