Scaphoideus lobatus VanDuzee. Bui. Buffalo Soc. Nat. Hist, V, 



No. 4, p. 211 (1894). 

 Catalogue Trans. Am. Ent. Soc, XXI, p. 300. 

 Osborn & Ball. Proc. Iowa Acad. Sci., IV, p. 232 (Record). 



Light yellow or white, with black spots and lines. Length, 

 9 , 6 mm. 



Vertex considerably wider than long, very obtusely angu- 

 lated in front, with scattered black, dark spots, the marginal 

 line broken into spots, or forming a curved line on either 

 side. Costal cell with numerous dark cross veinlets. 



Genitalia : 9 , last ventral segment long at middle, nearly 

 truncate, very slightly notched. d\ valve "small, brown; 

 plates narrow, their slender recurved tips brown and fringed 

 with long white hairs." 



This species was described from two specimens from Lan- 

 caster, N. Y., and two from New York City. It was taken at 

 Ames, Iowa, by Mr. E. D. Ball, August 7, 1897, and August 

 I 3> l8 97- I have one specimen from Madison, N. J., taken 

 August 6, 1898, and one from Mr. VanDuzee, taken at 

 Gowanda, N. Y., August 18, 1898. 



This species occupies a position by itself, and appears to 

 have affinities with either Kutettix Or Paramesus. The post- 

 nodal cell is narrow, and the presence of cross veinlets in the 

 costal cell are exceptional. However, the shape of vertex 

 and front scarcely permit its reference to a different genus, 

 unless one be created for its reception. 



Scaphoideus ochrackus Osborn. (Plate IX, Fig 3.) 

 Scaphoideus ochraceus Osborn. Proc. Iowa Acad. Sci., V, p. 242, 1898. 



Tawny ochraceous and pallid with most of the elytral 

 nervures fuscous. Length to tip of elytra, 9 6 mm., cT 5 mm. 



Vertex as long as width between the eyes, nearly as long 

 as pronotum, the margin angularly rounded ; front, narrow ; 

 margins slightly concave next the antennae, tapering uni- 

 formly to base of clypeus, which it equals in width. Clypeus 

 twice as long as width at base, broadening to the apex, which 

 is distinctly truncate ; lorse oval, sub-angulate at tips, twice 

 as long as wide; gense broad, slightly concave below eyes
