In place of the grooves, the intermediate and posterior tibiae may 

 have a central longitudinal carina as in Galerita dccipiens and in 

 Badister piilchellus; in v\diich case, the crest usually carries a row 

 of coarse punctures bearing spinules. In Lebia grandis the exterior 

 faces are compresso-carinate and the crest carries such a series. .In 

 HelliioDiorpha bicolor the whole tibia is compressed and the narrow 

 external edge is sharply and deeply grooved. These grooves are 

 open at the apex. The carinate edges are spinulose-punctate, more 

 strongly in the intermediate pair. In the intermediate pair the punc- 

 tures are exactly on the crest; in the posterior pair they are more on 

 the outer side of the carinse. In Philophnga viridicollis both pairs of 

 tibise are grooved, but the limiting carinse are indistinct and the 

 grooves are not open behind. The row of punctures on both pairs 

 in this species are slightly off the crests. In Tetragonoderus fas- 

 ciatits a row of spine-bearing punctures is found in an anterior posi- 

 tion on the intermediate tibise, though no groove is present. The 

 corresponding posterior row is less numerous or entirely absent. In 

 Pterostichus stygicus, coracinus and mocstus there is a row of three 

 or four large punctures on the apical third of the intermediate tibise. 

 These are not on the center line but slightly anterior in position. 



The antero-exterior apical margin of the intermediate tibise in 

 Harpalus, Chlcrnius, Calosoma or Cychnis bears a fringe of close-set 

 spinules. In a male Platymis angusfatns or a male Pterostichus 

 ater this fringe is strongly arcuate, concave to the margin. The 

 fringe does not mark an emargination, however, for the apex is 

 entire beneath the fringe. In a male of Pterostichus lucuhlandiis 

 the feature is most strongly developed. In that species it is further 

 removed from the apex, straight and free at both ends. In the 

 males of the subgenus Cyrtonotus of the genus Amara the interior 

 face of the intermediate tibise is dentate or bisinuate; in the males 

 of the genus Discoderns the tibise are strongly arcuate and denticu- 

 late within. 



The tarsi in the Carabidse are five-jointed and the last joint bears 

 two claws at its apex. The first joint is always the longest, but in 

 the Harpalinse unisetosse the difference between the first and second 

 joints is sometimes not very great. In Onota floridana, on the other 

 hand, the first joint of the posterior is equal in length to the next 

 four. The tarsi of the posterior legs are always the longest and
