The strong p< >i tits of resemblance an- as follows: 



The antennae are closely approximated, inserted in a deep <inus ; the labrum is indis- 

 tinct, being connate with the clypeus, which is dilated in front of the antenna?: the first 

 joint of the antenna' is elongate; the anterior coxsb are more wideh separated than in the 

 true Elateridae, and the posterior spine i< sh >rt; the I isl pint <.! the palpi is very large 

 and triangular; the tarsi an' short, and the claws pectinate.

 The genera of this di\i-i<>n are very numerous, and seem to have been very uni 

 sarily multiplied on slight grounds. I • j an- all characterized by having the mandil 

 small and retract i-d. ami the antennae widely separated, inserted ver) mar tl in deep 



foveae: the clypeus is never dilated anteriorly, and the labrura is always distinct. The fol- 

 lowing table expresses tin' relations of the genera found in tin- country, in a tolerably na- 

 tural manner, though th" necessity of introducing several nev* i, mostl) foi
