Cladognathus (Prosopocoelus) 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 Avhich 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 tibiiB 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 tw'o-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 ; elyti'a deeply and closely 

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

 and in the posterior part ; posterior tibige 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.
