OIlDEIl COLEOPTERA. 545 



The base of the jaws is uncovered. These insects are more- 

 over proper to South America, while zophosis and erodius 

 inhabit exclusively the western and southern parts of Asia, 

 and the south of Europe and Africa. (G. nodosa^ Germ. 

 Insect. Spec. Nov.) 



Other pimelise, terminating the subdivision of those whose 

 labrum is not received into any deep emargination of the 

 anterior edge of the head, and in whicli this last part of the 

 body is neither truncated in front nor narrowed behind, are 

 distinguishable from the foregoing by the following charac- 

 ters. The anterior edge of this part is advanced like an angle 

 or tooth in the middle. The labrum, when the mandibles 

 are closed, appear not at all, or but very slightly. The cors- 

 let is sometimes in the form of a trapezium, nearly as long as 

 it is wide, sometimes nearly orbicular, or almost semicircular. 

 The antennae are filiform, and the eleventh and last articula- 

 tion is always very distinct from the foregoing. The men- 

 tum is encased underneath, and covers the base of the jaws. 

 The presternum is a little elongated into a point in many. 

 These insects, as well as those proper to the two following 

 subdivisions, are exclusively proper to the warm and western 

 countries of the Old World. 



Hegetjer, Lat. 



Have the corslet in form of a trapezium nearly as wide at the 

 posterior edge as the base of the elytra, and applied along 

 its whole length against it. The last articulation of the an- 

 tennae is a little smaller than the preceding.* 



Tentyria, Lat. Akis, Fab. 

 Their corslet is nearly orbicular, sometimes narrower than
