those of the anterior the shortest. In the majority of the species 

 the first joint is equal in length to the next two or three. The first 

 is always wider at the base than the others. The joints of the ante- 

 rior tarsi are more or less flattened and triangular in form and the 

 joints of the posterior more or less cylindrical, excepting the tribe 

 Dapti and the genus Agonodcrus. 



The fourth joint throughout the family is rarely more than 

 slightly longer than wide, even in such long-legged species as Scaphi- 

 notus angusticolUs, Platynus caiidatus or Platynus angustatus. The 

 genera Laclinocrcpis and Oodcs are exceptions. The legs in these 

 genera are only moderately long, yet the fourth joint is distinctly 

 elongate. In the subfamily Carabinae, except in the genus Prome- 

 cognathus and the Harpalid genera Nomiiis, Psydrus, Morio, Bem- 

 hidinm, TacJiys and Trechns, the fourth tarsal joint is not emarginate 

 at apex. In the remaining genera the fourth joint at least is always 

 more or less emarginate. In Agonodenis the fourth joint of the 

 anterior tarsi only is emarginate, but usually the fourth joint of the 

 posterior tarsi is not perceptibly less emarginate than that of the 

 anterior. 



In the males of the genus Ptcrostichiis the first joint of the ante- 

 rior tarsi is nearly as strongly emarginate as the fourth and the third 

 is the least sti^ongly emarginate. Elsewhere the third joint is some- 

 times very slightly emarginate in addition to the fourth, but the 

 second and first are always truncate. In many genera of the Lebiini 

 and the genus Stenolophus the fourth joint is bilobed; in Stcnolophus 

 only in the anterior and intermediate legs. 



In the males of most of the genera of the family, the anterior 

 tarsi have one or more dilated joints bearing squamulose hairs be- 

 neath. In Omophron the first joint only is dilated. In Bemhidiiim 

 and Tachys the first two Joints are dilated. In most of the genera 

 the first three joints are dilated. In Tachycellus the first dilated 

 joint is slightly narrower than the second; in Anisodactylus it is still 

 narrower; in the other genera the first is equal in width to or wider 

 than the second joint. In the tribe Dapti and the genus Agonoderus 

 the anterior tarsi are similar in both sexes. In the Cychrini, omit- 

 ting the genus Sphccroderus, and in the genus Platynus the anterior 

 tarsal joints of the male are very slightly dilated. 



In the genera Bcmhidium, Tachys and Loxandrus the inner angles
