284 INSECTA. 



length; body fulvous with black elytra, terminated by a yellow- 

 ish-fulvous spot; elytra slightly striate, the striae punctate with 

 two more deeply impressed puncta near the third, commencing 

 from the suture( 1). 

 In the following, the thorax terminates posteriorly in a straight 

 line without any central projection. 



Plochioxus, Dej. 



The antennae almost granose; last joint of the labial palpi large, 

 nearly securiform; four first joints of the tarsi short, in the form of 

 a reversed heart, the fourth bilobate(2). 



Orthogonius, Dej. 



Similar tarsi; but the antennae are filiform, and the external palpi 

 terminated by an almost cylindrical joint(3). 



Coptodera, Dej. 



The palpi of the preceding; antennae more or less granose; three 

 first joints of the anterior tarsi short and wide; the same of the 

 four posterior tarsi, almost filiform; the penultimate joint of all bifid, 

 but not bilobate. All the species quoted by Count Dejean are 

 foreign to Europe, and belong, generally, to America(4). 



2. The second section, that of the Bipartiti, Scaritides, Dej. 

 which in relation to their habits might also be styled Fossores, is 

 composed of Carabici with elytra either entire or slightly sinuated 

 at their posterior extremity; having frequently granose and geni- 

 culate antennae; a broad head, large thorax, usually shaped like a 

 cup or almost semi-orbicuiar, and separated from the abdomen by 

 an interval which causes the latter to appear pediculated; the legs 

 generally but slightly elongated, their tarsi usually short, and simi- 

 lar in the two sexes, or nearly so, without any brush beneath and sim- 

 ply furnished with ordinary hairs or cilia. The two anterior tibiae 

 are dentated, and in several palmated or digitated; the mandibles 

 frequently strong and dentated. There is a tooth in the emargina- 

 tion of the mentum. They all keep on the ground, conceal them-
