each other beneath, finely granulate ; club of antennae

II, Club of antennae more or less distinctly articu- 

 late ; tarsi usually spongy beneath, with third joint 

 bilobed ; peduncle of submentum not reaching level 

 of front of emargination. 



1, Epimera of mesothorax visible above between 

 thorax and elytra ; intermediate abdominal seg- 

 ments nearly always curved or angular at ex- 

 tremities. 



A A. Scutellum distinctly visible. 



Eostrum often thickened at base, scrobes turning quickly 

 on to under surface and invisible on sides, except in front ; 

 prosternum somewhat rarely channeled ; pygidium some- 

 times covered by elytra, sometimes uncovered ; tibiae in 

 most cases hooked at apex, but usually feebly ; tarsal claws 

 free or soldered. Baridi(i%s. 



IB 2?. Scutellum not or scarcely visible. 



Eostrum not thickened at base, scrobes generally con- 

 tinued along lower part of side and visible wholly or in 

 great part ; prosternum very often channeled or hollowed 

 out ; pygidium not covered by elytra ; tibiae not or scarcely 

 at all hooked at apex ; tarsal claws not soldered.

2, Epimera of mesothorax not visible above ; in- 

 termediate abdominal segments straight behind. 



A A, Antennae not elbowed. 



Eostrum long, abruptly bent, forming an acute angle 

 with head, received when at rest into a channel on pro- 

 sternum, scrobes placed rather high, rounded, contiguous to 

 eyes ; channel on prosternum reaching mesosternum but 

 not continued on to it; eyes very large, oval, contiguous on 

 forehead ; scutellum absent ; elytra covering pygidium ; 

 posterior legs formed for leaping ; tibiae not hooked at 

 apex ; tarsal claws simple. Bamphides.
