Subfamily II. HARPALINAE. 



The members of this subfamily have the epimera of the meso- 

 sternum variable in w-idth but uot reaching the coxa, the middle 

 coxal cavities therefore enclosed on the outer side by the junction 

 of the meso- and metasterna ; head marked with one or two bristle- 

 bearing punctures over eacli eye ; thorax with a similar puncture 

 at the side and another at the liind angle, very rarely without the 

 latter and still more rarelv without either; front tibia? always 

 either obliquely siiuiate or deeply emarginate within, the inner spur 

 remote from apex. 



For convenience the sul)family was divided by Horn into two 

 great groups or sections as follows:
