the anterior two-thirds on the same incHned plane as the vertex then 

 strongly rounding into the line of the convex scutellum. Elytra 

 broad, coriaceous, venation obscure except towards the apex, outer 

 anteapical narrow, curving around the end of the adjacent discoid 

 cell ; posterior veinlets distinctly curved. Posterior tibia weak, a 

 single long spine before a rather weak terminal crown of spines. 



Color brown, the vertex and anterior half of pronotum washed 

 with yellow; face black, the anterior margin yellow; elytra with a 

 pair of white spots just in front of the middle of costal margin 

 from which narrow crescents extend in onto the claval areas, a sim- 

 ilar pair of spots on costa half way to apex and large white areas 

 occupying the first three cells and the bases of the ones adjoining. 



Described from a single female from Port au Prince, Hayti, taken 

 in February by R. J. Crew. 



Enocornia ovata n. sp. (Figure 39, Fig. 2.) 



Size and general appearance of a Clastoptem. Pale brown with 

 eight or more spots. Length, 4 mm. ; width, 2 mm. 



Vertex short, obtusely rounding, two-thirds the length of the pro- 

 notum, disc strongly sloping, the margin thick. Front convex, the 

 disc depressed. Pronotum broader behind than in aiiipliafa, scutel- 

 lum smaller, shorter and less convex than in that species. Elytra 

 long-oval, coriaceous; venation indistinct, first anteapical cell larg:. 

 apical cells short, almost rectangular. 



Color pale testaceous brown, darker below, the margin of the 

 vertex and apex of elytra lighter, eight or more round white spots 

 as follows : A pair on costal margin before the middle, another pair 

 on costa behind the middle, a pair just inside of these in the ante- 

 apical cells and usually one or two points on the disc. 



Described from three examples from Jamaica, W. I. This is the 

 smallest species in the Cercopid group outside of the genus Clas- 

 toptera. It is closely related to aiiipliafa. but is much smaller and 

 more compact. 



Lcocoinia n. gen. 



Resembling Lcpyronia in general form, but with the elytra more 

 rounding ai)ically and the marginal vein of the under wing entire. 



Vertex long, flat, parabolic in outline, the anterior margin thin, 

 inclined to be foliaceous. Face very flat, profile straight and the 

 extended line touching the costa. Head distinctly narrower than 

 pronotum. Pronotum and scutellum as in Lcpyronia. Elytra
