Subfamily III. PEROTHOPINAE. 



In this subfamily the antenna- are well separated at l)asc and 

 arise from small pits beneath well-marked frontal ridges, at a dis- 

 tance in front oE the eyes; the mouth is inferior; labrum transverse, 

 curved in front, closely united with th(> clypeiis; prosternum slightly 

 lobed in front, the spine very sh(n't ; front coxa> small, globular, 

 without trochantin ; middle coxsp oval with a small trochantin ; hind 

 coxfp transverse, the plates broadly dilated on the inner side; tarsal 

 claws with comb-like teeth. The sulifamily is I'epresented by the 

 single genus:
