1898.] . of the Coleoptera of South Africa. 367 



Allied to P. striatitarsis, Catal., p. 577, but the prothorax is 

 shorter and therefore more cordiform, the elytra are slightly con- 

 stricted behind the humeral part, and a little more convex, the 

 stria? and also the punctures are deeper ; the antennae with the 

 exception of the three basal joints are deeply infuscate. Length 

 7 mm. ; width 3 mm. 



Hab. Cape Colony (Uitenhage). 



This species follows P. striatitarsis. 



Platynus fallaciosus. 



Black, shining ; prothorax very faintly senescent, shining ; antennae 

 infuscate with the exception of the three basal joints which are sub- 

 rufescent ; femora fuscous brown, tibiae light brown ; thorax elongate, 

 cordiform, not angular laterally towards the median part, disk 

 smooth ; elytra elongato-ovate, rounded at the shoulders, a little 

 convex on the posterior part, striate with the striae finely punctulate. 

 This species is closely allied to P. Icetulus, but it is a little more 

 robust, the prothorax is not aculeate laterally, and it is darker in 

 colour. Length 7 mm. ; width 2i-3 mm. 



Hab. Natal (D'Urban). 



Follows P. l&tulus. 



Platynus velox. 



Head piceous-red, shining ; antennae, prothorax and legs very light 

 reddish brown, elytra piceous-red with a narrow flavescent border ; 

 palpi infuscate, sub-flavescent at tip ; head smooth ; antennae very 

 long, slender; prothorax nearly as broad as long, not cordiform, but 

 slightly narrower at base than at apex, with the outer margins much 

 recurved ; the median part of the disk is reddish brown ; elytra dark 

 brown with a narrow reddish-brown margin, elongate, nearly straight 

 laterally and with the shoulders sub-diagonal, attenuate behind, 

 depressed, very finely aciculate, narrowly striate with the striae 

 faintly punctulate, intervals plane, third one with three equidistant 

 punctures placed close to the stria ; in the two examples I have 

 seen, the suture is also lighter brown than the disk. Length 

 8 mm. ; width 3 mm. 



The shape of the prothorax is not at all cordiform, and is more 

 like that of Euleptus, but not so slender, and the general facies is 

 slightly more massive. It should come last of the South African 

 species. 



Hab. Natal (Ulundi).
