Cratognathus maxillosus. 



Size, shape, and colour of C. mandihularis ; the palpi, antennae, 

 and legs are more rufescent, and the labrum is very short and 

 narrow, almost rudimentary, thus exposing the whole of the 

 mandibles, which are very long and hooked apically ; the elytra are 

 also a little more elongate. Length 10 mm. ; width 3 mm. 



I have seen only one male example of this interesting species, 

 captured near Kimberley by Mons. Eugene Simon. 



Ceatognathus grandiceps, Bohem. 

 Harpalus grandiceps, Vet. Acad. Forh., 1860, p. 12. 



Head black, with a bronze sheen; prothorax bronzy in the centre 

 of the disk ; elytra ferruginous, with the sutural part of the disk 

 fusco-asneous ; palpi, antennae, legs, and the two abdominal segments 

 flavescent ; head large, nearly smooth ; labrum slightly rufescent, 

 long, incised ; prothorax broad, nearly smooth, of the same shape as 

 C. mandihularis, and with the posterior angles equally acute ; elytra 

 short, elongate, subparallel, striate, intervals plane, the third interval 

 with the customary puncture close to the second stria ; under side 

 piceous. Length 7 mm. ; width 3 mm. 



Hah. Damaraland (Nolagi Eiver). 



Boheman's type (a male) is the only example of this species that 

 I have seen. 



Ceatognathus fallax. 



Black, very shining ; labrum, palpi, antennae, and legs rufescent ; 

 labrum long, deeply incised ; mandibles long, the right one bidentate 

 inwardly, the left one with a median inner tooth in the male ; head 

 and prothorax smooth, shining, the latter truncate at the apex, 

 sinuate at the base, a little ampliated in the anterior part, slightly 

 attenuate from the median to the posterior part, but not sinuate, and 

 with the posterior angles conspicuously rounded ; elytra elongate, 

 sub-parallel, short, hardly broader than the prothorax ; striate with 

 the intervals plane, the third one without any puncture in the 

 posterior part ; under side piceous. Length 9 mm. ; width 4 mm. 



Smaller and a little more parallel than G. mandihularis, and easily 

 distinguished from it by the rounded posterior angle of the prothorax. 



Hah. Cape Colony (Worcester).

The only difference between this genus and the preceding one 

 consists in the basal joint of the anterior tarsi, being as squamulose 

 as the three intermediate ones ; the tip of the basal joint of the inter-
