CARABIDAE. 2t 



Episterna of metathorax variable ; elytra with none or several dorsal 

 punctures ;* 

 Ligula flat or slightly convex ; presternum not channelled, sometimes 



margined. Ptekostichus. 



Ligula carinate ; episterna of metathorax elongate ; presternum not 



margined nor channelled. Lophoglossus. 



Ligula carinate ; episterna of metathorax short ; prosternum margined 

 and channelled. Holciophorcs. 



Mentum tooth obtuse, scarcely concave ; palpi slender, last joint cylin- 

 drical ; episterna of metathorax elongate ; elytra with one dorsal 

 puncture. Loxandkus. 



Mentum tooth emarginate, rarely entire ; head not at all narrowed behind ; 

 lab rum slightly emarginate ; last joint of palpi slightly oval ; elytra 

 without dorsal punctures. Amara. 



Tribe ix.— licinini. 



The paraglossae in this tribe are variable in form, sometimes 

 (Badister) entirely connate with the ligula, sometimes (Diploehila, 

 Dicaelus) free at the apex. The head is large and obtuse; the 

 labrum is emarginate, and deeply impressed; the mandibles are 

 obtuse. Three basal joints of the antennae are smooth (the third 

 is slightly hairy in some species of Badister, but not rough like the 

 following joints). The anterior tibiae are somewhat thickened and 

 spinous at the tip; the anterior tarsi of the male have three (in 

 some foreign genera only two) joints strongly dilated, covered 

 beneath with a dense brush of hair. The elytra are slightly and 

 obliquely sinuate at the apex; one dorsal puncture is seen on the 

 third interval. The body is never hairy. 



In our genera the clypeus is divided into an anterior subcoria- 

 ceous, and a posterior corneous portion, and the mentum is not 

 toothed. 



Last joint of palpi oval ; 



Paraglossse connate with the ligula, and longer than it. Badister. 



Ligula free at the apex. Diplochila. 



Last joint of palpi slightly securiform. Dicjelus. 



The species of the first genus are small, frequently prettily spot- 

 ted insects, found under stones; they are rare, and occur on both 



* Except in Pterostichus konestus (Fer. fastidita Dej.), in which a single 

 dorsal puncture is seen. This species is, however, of the same form as P. 

 adoxus, and would not be confounded with the very characteristic forms of 

 any of the groups of Evarthrus.
