„ Although the characteristics of this genus, which Erichson con- 

 sidered to be new, are very slight, the peculiar form of the claws 

 which has given the genus its name are sufficient to prevent the 

 only known species from being included in the genus Platynus 

 {Anchomenus and Agonu7n). The mouth does not show any im- 

 portant difference ; the antennae and mandibles are similar except 

 that the latter are a little more incurved at tip ; the labrum projects 

 somewhat more and is more rounded ; the mentum is as in Agonum, 

 and has the same median tooth ; the ligula is relatively somewhat 

 longer and the paraglossse project a little; the palpi show no per- 

 ceptible difference ; the prothorax is not cordate, but as broad behind 

 as in front and rounded at sides and corners. The most important, 

 if not sole difference of the genus consists in the peculiar shape of 

 the tarsi and especially of the claws ; the joints are of equal length 

 in the anterior legs, while in the hind ones the two basal ones are 

 longer than each of the two following, which again are of equal 

 length ; the nondentate claws are not, as in Agonum, curved, but 

 straight and sharp, they lie so close together as to give the appear- 

 ance of there" being a simple claw cleft at tip.
