lobe with two parallel, strong, not hamate teeth, inner lobe with 

 one tooth only set almost between the two upper teeth ; clypeus 

 plane, marginate in front, the margin strongly reflexed, head simple; 

 eyes large ; antennae of the normal shape ; prothorax hexagonal 

 with the basal angles distinct ; scutellum broad at the base but only 

 moderately long ; elytra plane, much broader than the prothorax, 

 deeply sinuate laterally, and with the humeral part very much raised, 

 the suture is depressed for the greater part of the length, and there 

 is on each side a high costa which is continued from the humeral 

 part to the apex ; pygidium vertical ; the spiracle of the last abdominal 

 segment sharply tuberculate ; anterior tibiae strongly bi-dentate ; 

 tarsal joints, even the last, short, strongly nodose ; claws very weak; 

 prosternum with a vertical, ante-coxal process. 

 This genus includes only one species. 



PlLINURGUS SUBUNDATUS, Westw., 



Thesaur. Entomol., p. 32, pi. ix., fig. 1. 



Black, moderately glossy, and covered with a muddy, somewhat 

 squamose coating ; head and clypeus deeply scrobiculate punctate 

 and sparingly hairy, anterior part of the clypeus strongly marginate 

 with the median part quite transverse and strongly reflexed ; pro- 

 thorax as ampliated laterally from the anterior part to the centre 

 which is somewhat sharp, as from the base to the centre, the 

 base itself is slightly sloping on each side of the median part, 

 the angles are very plain, it is moderately grooved longitudinally 

 in the posterior part of the disk, covered with round, rugose, con- 

 tiguous punctures, briefly setigerous ; scutellum indistinctly strigose 

 punctate ; elytra one-third broader at the base than the prothorax, 

 and having on each side a high costa reaching from near the base 

 and coalescing a little below it with the humeral ridge, to the 

 apex, and situated nearer to the deflexed side than to the not 

 raised suture, the discoidal part below the scutellum is strongly 

 impressed, and the surface is covered with oblong, strongly cica- 

 tricose, non-contiguous punctures ; propygidium and pygidium 

 aciculate, the latter sub-lanuginose ; under side roughly cicatricose 

 punctate. 



I know nothing of the habits of this species which is met also near 

 Lake Tanganyka.
