Anoplus, Schoenh. 



2, Fourth tarsal joint present. 



Eostrum elongate, scrobes oblique ; antennae moderately 

 long, first joint of funiculus elongate, rest very short ; scu- 

 tellum scarcely visible ; second abdominal segment as long 

 as third and fourth together, separated from first by a 

 straight suture ; presternum strongly emarginate in front ; 

 tarsi short, spongy beneath, third joint bilobed, broader 

 than first and second. Smicronyx, Schoenh. 



II, Funiculus of antennae with six joints. 



Antennae moderately long, first two joints of funiculus 

 somewhat elongate ; second abdominal segment as long as 

 third and fourth together, separated from first by a curved 

 suture ; tarsi short, spongy beneath, third joint bilobed, 

 broader than first and second. Tanysphyrus, Schoenh. 



h. Fourth tarsal joint reaching much beyond front of 

 third. 



J. Tarsi very slender, not spongy beneath, third joint 

 not or scarcely broader than first and second, not 

 bilobed. 



1, Funiculus of antennae with second joint longer 

 than first. 



Antennae moderately long, funiculus with six or seven 

 joints ; presternum more or less hollowed out ; second 

 abdominal segment distinctly longer than third and fourth 

 together, separated from first by a straight suture. 



Bag Otis, Schoenh. 



2, Funiculus of antennae with first joint longer 

 than second. 



Similar to Bagous, but with club of antennae less com-
