ones with a small fringe or brush of fulvous hairs on each side of 

 the apical part. 



The genus seems to be represented all over the globe, except in 

 America. 



Cladognathus (Peosopocoelus) natalensis, Parry, 

 Transact. Entom. Soc. Lond., vol. ii., 3rd ser., 1864, p. 36. 



Dark chestnut-brown on the head and prothorax, much lighter 

 chestnut-brown on the elytra, the suture of which, however, is dark. 



Male : Mandibles as long as the head, curved laterally for a third 

 of the length, produced slightly obliquely from there, sub-falcate at tip, 

 strongly and equally dentate in the lower inner margin which is 

 deeply emarginate at base and leaves a moderately broad open space, 

 and with an inner basal tooth and two round, knobby ones at the 

 base of the upper margin ; head transverse, a little broader in the 

 anterior than in the posterior part ; the former is sinuate or slightly 

 incised near the outer angle, the posterior angle is somewhat obtuse, 

 or not very sharp ; the eye is not much divided behind ; prothorax 

 broader than the head, sub-parallel laterally, or very slightly attenuate 

 from the anterior angle which is somewhat rounded, to the posterior 

 which is very sharp at tip and obliquely attenuate ; it is covered like 

 the head with a fine aciculation forming a very finely shagreened 

 surface ; scutellum punctulate ; elytra very finely and closely 

 punctate, but only finely aciculate in the large development and 

 having only a faint trace of a supra-marginal stria ; under side 

 glabrous, finely aciculate, a little darker than the upper side but 

 always with a redder or lighter transverse patch on each side of the 

 metasternum ; posterior tibiae without spine. 



Female : Very much smaller than the male ; mandibles short, 

 bi-carinate on the upper side ; head deeply foveolato-punctate, gense 

 dividing the eye for two-thirds of the length and projecting much ; 

 prothorax gradually ampliate laterally from the anterior angle to 

 the posterior and very obliquely truncate towards the base, deeply 

 and roughly foveate laterally and with only a few scattered 

 punctures in the centre of the disk ; elytra deeply and closely 

 punctured in the dorsal part and foveolato-punctate on the sides 

 and in the posterior part ; posterior tibiae with one spine ; the 

 elytra, in spite of being much more deeply punctured than in the 

 male, are more shining. 



Length (exclusive of mandibles), 20-36 mm. ; width 9^-15 mm.
