ORDER COLEOPTERA. 211 



The fourth section, that of Simplicimani, approaches the 

 preceding, as to the mode in which the elytra terminate ; but 

 the two anterior tarsi alone are dilated in the males ; never- 

 theless, without forming a squared or orbicular pallet. 

 Sometimes the first three articulations are by much the 

 broadest, and the following is then always much smaller 

 than the preceding. Sometimes this last and the preceding- 

 two are wider, almost equal, and in the form of a reversed 

 heart or triangular. The first articulations of the four fol- 

 lowing tarsi are more narrow, and more elongated, almost 

 cylindrical, or in the form of an elongated and reversed cone. 



Some have the crotchets of the tarsi simple, or without 

 denticulations. 



Here the third articulation of the antennae is, at the most, 

 once longer than the preceding. The feet are generally ro- 

 bust, with the thighs thick, more or less ovaliform. The 

 corslet, measured in its greatest transverse diameter, is as 

 wide as the elytra. 



Sometimes the mandibles are evidently shorter than the 

 head, and do not pass the labrum but by one half, at the 

 most, of their length. 



We shall commence with those, all of whose external palpi 

 are filiform. 



Zabrus, Clairv. Bon. Pelor. Bon. 



Are distinguished from the following by the last articulation 

 of their maxillary palpi, which is sensibly shorter than the 

 preceding, and by the two spines which terminate their ante- 

 rior legs.* 



PoGONus, Zieg. Dej. 

 Which in the natural order appear to us very much approxi-
