narrow, elongated, with the corslet almost square. The first 

 articulations of the four (male) or two (female) anterior

 emarginate. 



These insects are proper to Australasia.* 



Macuodactylus, Lat. 



Resemble the Diphucephala, as regards the hooks of the 

 tarsi, and the elongation of the body ; but here the corslet 

 is longer, almost hexagonal, and all the articulations of the

 hairy. These insects are peculiar to the New Continent. -f- 



In others, the hooks of the intermediate tarsi alone are 

 unequal, 



Plectris, Lepel. et Serv. 



The thickest of these hooks and the two of the other tarsi 

 are bifid ; the first articulation of the posterior tarsi is very 

 long.+ 



In the others, all the hooks of the tarsi are unequal. 

 Those of the posterior two, at least, are always entire. One 

 at least of the two or four anterior tarsi of the males, and 

 sometimes of the females, is bifid.
