44 ORDER COLEOPTERA. 



Genus CLIVINA (Latr.). 

 ' Labrum quadrate, transverse ; mandibles short, denticulated from the base to the apex ; 

 ' terminal joint of the labial palpi nearly cylindric ; basal joint of the antenna? stout, 

 ' the second long ; body elongated, subdepressed ; thorax quadrate ; anterior tibise 

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



Clivika LiNEOLATA (Say). ( Plate xviii, fig. 11.) 



Color light glossy brown ; thorax rounded behind and narrowed before, marked by three 

 distinct lines ; elytra .marked by distinctly punctate lines, of which there are about 

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

 Found under stones. 



Genus DYSCHIRIUS (Panzer). 



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

 mated. 



Dyschirius GLOBULosus (Say). (Plate xviii, fig. 15.) 



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

 tenths of a line. 



Harpalides. 



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

 also sessile, and not pedunculated. The anterior tibiae 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 antennae 

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

 dibles generally with one or more denticulations ; mentum deeply emarginate anteriorly, 

 the emargination simple or sometimes toothed ; body elongate. 



These insects are not so* voracious as those of the succeeding family, the Carabides- 

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

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

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

 elongate, but slightly flattened or depressed ; and they have twelve rings, which are more 

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



The sub-family contains many genera, which, though related to eacli other, are not 

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