OSBORN AND BALL STUDIES OF NORTH AMERICAN JASSOIDEA. 69 



Color: Face and pronotum bright saffron -yellow, scutellum light- 

 yellow, sometimes with the basal angles clouded. Elytra clouded 

 with brown, deepest on the claval areas and fading out to light-yellow 

 before reaching the costal margin, sutural and humeral margins with a 

 narrow saffron-yellow line. Below, light-yellow, claws brown, pro- 

 pleura unmarked. In two examples the elytra are scarcely clouded, 

 being light-hyaline yellowish throughout. 



Described from eight females and five males collected on honey lo- 

 cust at Lexington, Ky., by H. Garman. 



Its occurrence on this food plant suggests identity with the preced- 

 ing species, but aside from the striking and apparently constant differ- 

 ence in color (which might possibly be referred to fading or variabil- 

 ity) there seems to be some differences in form of head and other de- 

 tails which, if in any degree constant, would be of specific value. 



Pediopsis reversalis n. sp. 



Allied \.o piinctifrons but larger, in size intermediate between that 

 species and gleditschice. Light-green, the male with two broad, black 

 stripes across the face, tips of the legs, and a spot on the propleura 

 black. Length, ? 4.50 mm ; S 4 mm.; width, about r.25 mm. 



Head short, stout, more obtusely angled than in gleditschice, a line 

 across the eyes scarcely cutting off a third of the vertex, vertex with 

 much finer striations than in punctifrons, less excavated behind, the 

 disc equally convex, but not as strongly pitted in front. Elytra 

 moderately strong, venation regular, not strongly marked. 



Color: Light-green, pronotum and face washed with yellow in the 

 female, male with a broad black band along the upper margin of the 

 face extending down to the middle of the front in a triangular point; 

 below this, between the lower margins of the eyes, is a still broader 

 black band, propleura with a round black spot, tips of the anterior 

 pairs of tibise and tarsi annulate with black. In some of the males 

 the band on the face is reduced to three black spots, one on the apex 

 above and one just within and below each ocellus. The females are 

 entirely unmarked except that in some cases the propleura has a faint 

 spot. 



Described from twenty- four males and twenty- four females collected 

 from willows at Ames, Iowa, from the middle of June until into 

 August, and three males .^rom the Van Duzee collection from Col- 

 den, N. Y.
