crebre punctulatum ; prothorax amplus, longitudine tertio latior, basi 

 leviter sinuatus, distincte marginatus, sub-sinuatus, apice emarginatus, 

 angulis anticis acutis prominulisqus, posticis rectis, lateribus ad 

 medium rotundato-ampliatis, supra convexus, crebre punctulatus, 

 punctis ad latera vix distinctioribus : elytra obtuse ovata, rnedio 

 prothorace duplo latiora, postice parum acuminata convexa, pone 

 medium sub-abrupte declivia fere levia ; pedes breves, rugosuli, 

 femoribus anticis clavatis, tibiisque ejusdem paris exteriie sinuatis ; 

 processus prosternalis ut in P. myrmidon. Long. 21 mm. ; lat. 

 14 mm. 



The facies is less elongate than that of P. myrmidon, owing to the 

 elytra being less attenuate laterally past the middle and more 

 abruptly dehiscent behind ; the sculpture of the head and prothorax 

 is very different.

A very distinct species characterised by the elongate shape of the 

 fl\ tra which are very little attenuate behind. 



Hab. Cape Colony (Knysna). Dr. F. Purcell. 



The species hereafter described belong to the group of Psammodcs 

 (Ocnodes, Fahr.) scrobicollis, Fahr., characterised by oblong ovate 

 elytra, short legs with the anterior tibite broad, sharply carinate and 

 sinuate outwardly, and moderately slender antennae.
