CARABIDAE. 19 



Sub-Family HARPALINJE. 



Middle coxal cavities entirely inclosed by the central pieces of 

 the meso- and nietasternuni, the epimera not attaining the coxai. 

 Head with setigerous punctures over the eyes. Ti)orax with 

 setigerous punctures at the side and posterior angle, very rarely 

 without the latter, and still more rarely without either. Anterior 

 tibias always either obliquely sinuate or deeply emarginate within, 

 the inner spur remote from the apex. 



These characters seem to be the only ones in which all the 

 tribes agree. As there are many points in which wide differences 

 occur these will be left for discussion in their proper places. 



For convenince of study the sub-family may be divided in two 

 grand sections. 



Head with two supra-orbital setigerous punctures. Harpalin^ bisetos^. 

 Head with ono supra-orbital setigerous puncture. HARPALiNiE unisetos^. 



Small as this character may seem it is probably one of the 

 most invariable of any that have been suggested for the division 

 of this large series of genera and tribes. No exception occurs 

 in our fauna. - 



When two setas occur the anterior is close to the margin of the 

 eye in front, the posterior is a little remote from the eye opposite 

 the posterior margin. When there is one seta, it is almost 

 always a little removed from the margin of the eye, and is situated 

 opposite the middle of the eye or a little posterior to that point. 



It will be observed in glancing over the series of tribes and 

 genera that there are three well-marked types, Pterostichus, 

 Lebia, and Harpalus, closely related among themselves, around 

 which we may group other types, either more or less intermediate 

 between the three, or related to them as a centre and from thence 

 diverging with no definite affinity. It is therefore impossible 

 to construct any linear arrangement which will exhibit all the 

 evident relationships without at the same time interrupting other 

 equally evident affinities. 



The tribes which follow arc so placed that those which seem 

 to exhibit the closest affinity with the Carabinae are at the 

 beginning, with those following which seem to lead to the true 

 Harpaline type.
