faint greenish tinge. Face with a pale Hne on middle, another on 

 middle of vertex, and one on middle of scutellum. Three spots 

 on anterior margin of pronotum white. Length 3 mm. 



Perhaps very closely related to the two preceding and occurring 

 on herbaceous plants. 

 E. birdii Coding. 



Ent. News, i, 123, 1890. 



Vertex obtusely rounded in front, color yellow to green, a pale 

 stripe extending across vertex and pronotum, and often scutellum. 

 A pale spot either side of this on base of vertex and anterior por- 

 tion of pronotum. Elytra yellow smoky crossed by a darker band 

 at middle, sometimes fused with a dark area at base of clavus, and 

 a spot at apex darker. Length 3 mm. 



Occurs on a number of plants and shrubs, not an abundant

Typhlocyba Germar. 

 Eupteryx Curtis. 



Elongate, slender, vertex crescent-shaped, elytra exceeding 

 abdomen, appendix wanting. Wings without marginal vein, all 

 four veins extending to wing margin, not fused. 



Only a few American species belong here and feed upon plants 

 which, for the most part, are not of economic importance.
