having fifteen interstices on each elytron^ the other species being 

 P. guerini Gory, and P. pradieri Chaud. From P. guerini, it 

 is easily distinguished by the larger size, colour, reflexed border 

 of elytra without serrations, etc. It requires comparison only 

 with P. pradieri, from which it differs greatly by the more 

 convex form; prothorax wider, with base wider than apex (in P. 

 pradieri prothorax with base and apex of equal width, 4*9 mm.), 

 basal angles wider and less strongly produced backwards (the 

 base being less deeply emarginate than in any other species of 

 the genus); elytra far more convex (more convex than in P. 

 viridis), eighth interstice not catenulate, marginal channel much 

 wider, etc. 



Tribe Migadopini. 

 Genus Stichonotus. 



It should be noted, that the genus Stichonotus has the head 

 with the upper articulation-point of the mandibles with the head 

 covered by the lateral edge of the clypeus, a feature that is rare 

 in the family Carabidse; metasternum without apparent epimera; 

 four anterior tarsi in $ clothed with spongiose tissue beneath, 

 anterior tarsi short, joints 1-4 spongiose beneath; intermediate 

 tarsi with first joint stout, as long as the two succeeding joints 

 together, a small tuft of spongiose tissue on lower side near apex, 

 second and third joints lightly dilatate, and clothed with 

 spongiose tissue beneath.
