these forms, and it is possible intergrades may be found in 

 the Mexican fauna. 



One specimen from Florida in the Van Duzee collection, 

 three from Texas, collected by Aaron, in collection of Iowa 

 State College, one male from Florida from Prof. H. A. 

 Gossard, and one male from Jacksonville, Fla., from Mr.

 Scaphoideus picturatus Osb. Proc. Iowa Acad. Sci., V.,p. 243 (1898). 



Color pattern very similar to sanctus. Head more sharply 

 angular, reflexed veins less oblique or indistinct. Length to 

 tips of elytra, female 5 mm., male 4 mm. 



Vertex sharply angulate at the tip, as long as width be- 

 tween the eyes, and nearly twice as long at middle as next 

 eye. Front very slightly widening next antennae, tapering 

 Uniformly to base of clypeus; clypeus with sides parallel, 

 base and apex convex; lorse small, suboval; gense roundingly 

 angulate below the eyes. Pronotum sharply arcuate in front, 

 truncate behind, lateral margin extremely short ; scutellum 

 small, the elytra with the post-nodal veinlets irregular, the 

 first either absent or not reflexed, the second strongly re- 

 flexed, the middle and inner anteapical cells with distinct or 

 obsolete cross nervures. 



Color: Vertex, anterior part of pronotum, scutellum, face, 

 pectus, venter and margin of abdomen above, yellow or 

 greenish-yellow; two minute points next each eye, two short 

 oblique lines near tip, and a very slender median line on 

 vertex, three or four strongly curved arcs on the front, the 

 margins of the olivaceous areas, an oblique band near the 

 tip, and a submarginal border on the elytra, fuscous. The 

 elytra are fusco-olivaceous, interrupted with ivory white as 

 follows; a broad oblique band on the base of corium and 

 clavus paralleling the sides of the scutellum, a discal spot at 

 forking of the first sector, a commisural spot and a broad 

 band across the base of the anteapical cells. The nervures 

 are white on the white portions and also in the fuscous part 

 at apex. 



Genitalia: Female, ultimate ventral segment short, slightly
