422 Descriptive Catalogue [1896. 



faulty. Of this there can be no doubt, as I have been able to 

 examme the types of Dejean, De Chaudoh, and De Castelnau. 



According to the Munich Catalogue, species belonging to this 

 genus are found in North America, the Canary Islands, and South 

 Africa ; but Horn does not mention this genus in his essay on the 

 genera of Carabidae of Boreal America as occurring there. 



Synopsis of Species. 



Right mandible of male with one median inner tooth ; labrnm 

 deeply incised in the middle ; prothorax with the posterior angles 

 acute ; piceous, with a faint greenish tinge. 



f minor. 



Labrumlong \ mandihidaris. 



Labrmn short inaxillosus. 



Head and median part of prothorax infuscate ; elytra and legs 

 fiavescent grandiceps. 



Mandibles of male pluridentate ; posterior angles of prothorax 

 quite rounded fallax. 



Ceatognathus mandibulaeis, Dej., 

 Spec. Col., iv., p. 48 ; Iconogr., i., pi. 173, fig. 5. 

 C.pallipes, Chaud., Bull. Mosc, 1843, in., p. 399. 



Black ; palpi, antennae, and legs fiavescent ; lateral margin of 

 prothorax narrowly fiavescent ; elytra light piceous, with a greenish 

 bronze tinge ; head smooth, broad, a little bigger in the male than 

 in the female ; labrum long, deeply incised ; prothorax truncate at 

 base and apex, a little rounded and ampliated in the anterior part, 

 where it is as broad as the head and eyes, a little attenuate behind, 

 with the posterior angles sharp, moderately plane, and with a depres- 

 sion on each side near the posterior angle ; elytra elongate, sub- 

 parallel, short, broader than the base of the prothorax, the anterior 

 angle acute, and the shoulder briefly diagonal, striate, intervals plane, 

 smooth, third interval with a distinct puncture on the posterior part, 

 close to the second stria ; under side black. Length 9-10 mm. ; 

 width 3J-4 mm. 



Hab. Cape Colony (Cape Town, Stellenbosch, Worcester). 



Ceatognathus minoe. 



Might be mistaken for a small example of C. mandihularis, but 

 constantly smaller and darker, with a greener bronze tinge ; prothorax 

 of the female not so ampliate as in the male, although this occurs 

 occasionally in mandihularis ; in size it approximates C. capensis, 

 but the elytra are less parallel, and the posterior angle of the 

 prothorax is not rounded. Length 7 mm. ; width 3 mm. 



Hah. Cape Colony (Cape Town).
