1904.] Catalogue of the Golcoptera of South Africa. 7 



coxae covering the greatest part of the fifth abdominal segment, and 

 with the hind margin running nearly parallel with the lower margin 

 of the latter ; anterior tibiae bi-dentate, anterior tarsi moderately 

 long, intermediate and posterior much longer, claws cleft under- 

 neath, the lower tooth slightly wider than the upper ; hind coxae 

 dilated, hind tibiae slightly ampliated inwardly at a short distance 

 from the base, and with their inner margin provided with numerous 

 long, bristle-like spines, the upper with two tri-spinose keels en 

 chevron. 



The genus is, so far as is now known, restricted to the South 

 African region. The number of species has been unduly increased 

 owing to one kind having a very wide distribution in South Africa 

 (from the Caledon District in the Cape Colony to the Zoutpansberg 

 District in the Transvaal). In this species (P. fasciatipennis, the 

 colouration of which is very variable) the shape of the clasps vary 

 slightly (vide pi. xliii., figs. 19, 20 ; pi. xlvi., fig. 32). 



Key to the Species. 



A 2 . Elytra with a more or less distinct, fuscous tessellation. 



Antennal club fuscous, the first joint half the length of the 



other in the female navicularis. 



Antennal club flavous, the first joint only one-quarter of the 



length of the other in the female . . maciilipennis. 



A 1 . Elytra without any traces of fuscous tessellation. 



Straw-colour, prothorax iridescent tongaatsana.

Handb. d. Entom., vol. iv., 2, p. 181. 



Testaceous-red with a dark greenish-bronze sheen, head and pro- 

 thorax clothed with appressed greyish-white hairs, and also with 

 long upright ones on the latter part, intervals between the costules 

 of the elytra filled w T ith long greyish setae, under side densely villose; 

 clypeus deeply and somewhat coarsely punctate, frontal part also 

 punctate but not roughly ; antennae, including the club, reddish and 

 with the latter often slightly infuscate ; prothorax aciculate and with 

 scattered punctures bearing each an upright hair, the pubescence is 

 often less dense in the centra] part of the disk ; scutellum raised 

 longitudinally in the centre ; elytra elongated, slightly narrower at 

 the shoulders than across the median part, and not narrowed thence
