Genus Cl.n I\\\ (Latr.)- 

 • Labrum quadrate, trans\ erse ; mandibh s short, denticulated En m Che 1 ase to the aj < \ ; 

 ' terminal joint of the labia] palpi nearly cylindric; basal joint of the antenna stout, 



• the second long; body elongated, subdepressed 5 thorax quadrate,; anterior til >ian 



• palmated externally and at the tip' (Stephens). 



Clivina unlpi.ata (Say). ( Plate xvi ii , fig. 11.) 



Dolor light u r l">-\ brown ; thorax rounded behind and narrowed before, marked by three 

 distinct lines ; elytra mark< d by distinctly punctate lines, of which tin re arc al out 

 five to each elytrum. Length two- to three-tenths of a line. 

 Found under stones. 



Genus DYSCIIIRIUS (Panzer). 

 Body elongated, subcylindric at the tip ; thorax globular or globose; tibia? rarely pal- 

 mated. 



Dyschirivs globulosus (Say). ( Plate xviii. fig. 15.) 



Insect brown, glossy ; thorax globose, smooth ; elytra punctated. Length scarcely two- 

 tenths of a line. 



Da r pal ides. 



The elytra of this sub-family cover the abdomen ; the extremity is rounded : they are 

 also sessile, and not pedunculated. The anterior tibise are deeply notched near their tips, 

 and, in the males, the basal joints are dilated. The mentum is emarginate, though it is 

 occasionally entire : the centre of the emargination has generally a spine. The antenna? 

 are filiform ; labrum quadrate, rarely bilobate, but sometimes emarginate in front : man- 

 dibles generally with one or more denticulations ; nientum deeplj emarginate anteriorly, 

 the emargination simple or sometimes toothed ; body elongate. 



These insects are not so voracious as those of the succeeding family, the Carai 1 

 The predominant colors arc black, while a few of them are adorned with brillianl metal- 

 lic hues. Some are apterous, and run remarkably well. The larva, like the perfect ins< <t. 

 lives beneath stones, and feeds upon other insects or their larva'. They are cylindric and 

 eli 'iiaate, but slightly Battened 01 depressed ; and they have twelve rings, which are more 

 or less scaly : the last ring is armed with two small processes. 



The sub-family contains many genera, which, though related to each other, are Di I 

 readily separable into groups. Stephens divides them into three groups, viz :
