ORDER COLEOPTERA. 489 



denticulated along the internal edge, as in hoplia, to which 

 this sub-genus considerably approximates. 



Sometimes the two posterior tarsi have but a single hook. 

 Those of the others are unequal and bifid. 



Some of them have, like the preceding, but nine articula- 

 tions to the antennae. 



Lepitrix, Lepel. and Serv. Trichius, Melolontha, Fab. 



The body is short, with the corslet more narrow than the 

 abdomen, almost squared, and a little narrowed posteriorly. 

 The abdomen is broad, and the hinder feet large. The last 

 articulation of the maxillary? palpi is much longer than in the 

 preceding sub-genera. The terminal lobe of the jaws is very 

 small, in the form of a short triangle. 



The others have ten articulations to the antennae. 



The body is short, very hairy, with the hood in the form 

 of an elongated triangle, truncated, or very obtuse at the 

 end ; the palpi projecting, terminated by a long and cylin- 

 drical articulation, the maxillary lobe long, narrow, project- 

 ing at its extremity, and without teeth. The abdomen large, 

 and the hinder feet long. 



Pachychnemus, Lepel. and Serv. Melolontha, Trichius, 



Fab. 



Have the elytra narrowed towards their extremity, the thighs 

 and legs of the two hinder feet inflated, these last almost in 

 a knob, with one of the two spurs of the end much stronger 

 than the other. 



Anisonyx, Melolontha, Fab. 



Whose elytra form a long square, rounded posteriorly, in 

 Avhich the hinder legs are almost cylindrical, or in the form 

 of an elongated cone, with the two spurs of the end of equal 

 size.
