 obtusely dentiform process on each side near 

 the base. Femora somewhat thickened, with 

 two or three little spines beneath near the lips. 

 $J Ocelli distinct. Scutellum unarmed on each side 

 at the base. Femora not or but slightly 

 thickened. Antennae moderate. 

 § Antennae remote from the eyes. 

 X Antennae seated near the tip of the head and about 

 thrice nearer to it than 10 the eyes. Head 

 longer than the prothorax. First and third 

 joints of the rostrum short, almost equally 

 long; secon.d very long, nearly four times 

 longer than the first. - 



X X Antennae variously inserted, remote from the tip of 

 the head, sometimes seated a little more remote 

 from the eyes than from the tip of the head. 

 o Fore lobe of the prothorax with two spines in the 

 disk ; side angles of ihe hind lobe ending in an 

 acute spine. Scutellum lengthened at the lip 

 into a long acute slightly reflexed spine. 

 Antennae seated a li t tie more remote from the 

 eyes than from the tip of the head; first joint 

 reaching or almost reaching the tip of the head. 

 First joint of the rostrum a little shorter than 

 the second. - 

 oo Fore lobe of the prothorax sometimes tuberculate, 

 never acutely spiny; lateral angles of the hind 

 lobe rounded. Scutellum lengthened at the 

 tip into an acute spine. 

 H- Body wiih short hairs. Prothorax distinctly 

 straightened ; lateral angles of the hind lobe a 

 little prominent; fore lobe quadrituberculate; 

 middle tubercles high, conical. 



-+-»- Body smooth. Prothorax sin ua ted on each side, 

 not or but slightly straightened ; fore lobe some-
