mesoscuto-scutellar suture and the furrows defining the triangular 

 shaped area of the propodeum are foveolate. The legs beyond 

 the bases of the femora are black. 



Paramellinus Rohwer. 



P. bipunctatus (Say). 



This is the only species of Paramellinus known in the East. 

 It is shining black with white markings. The second and third 

 dorsal abdominal segments have lateral whitish spots. The 

 wings are clear. The recurrent veins are usually interstitial with 

 the first and second transverse cubiti. The eyes are large, oval in 

 outline, being closer together a short distance above the antennae.

HOPLISINI. 



Hoplisus LePeletier. 



The species placed in the genus at present may belong in a 

 number of different subgenera when the group is studied from the 

 standpoint of the genotypes. The species, as far as known, prey 

 on leaf-hoppers and nest in the sand. For an interesting account 

 of canaliculatus Packard, see Barth, Bull. Wisconsin Nat. Hist.

The following table is based on the females, as the males of 

 but a few of the species are known.
