OSBORN AND BALL STUDIES OF NORTH AMERICAN JASSOIDEA. 67 



Pediopsis suturalis n. sp. 



Form oi ferruginoides nearly, bright-green with the the entire claval 

 areas black, approaching basalis in size and ornamentation, but with 

 a much more produced vertex. Length of ?, 6 mm.; width, 1.75 

 mm. c^ smaller. 



Vertex little more than half the length of the eye, forming nearly a 

 right angle in front, the center of the eye behind the middle of the 

 vertex; front very flat, acutely angled above; pronotum finely wrin- 

 kled, nearly twice longer on middle than across the humeral angle to 

 the eye, posterior margin shallowly emarginate, el)tra long, round- 

 ingly angled behind. 



Color: Bright green on face, pronotum and scutellum, a black 

 stripe arising just back of either eye, widening backwards to the hu- 

 meral angle, usually leaving a small green spot on the outer angle of 

 the pronotum next the eye, the entire claval area of the elytra deep 

 black, sharply and definitely bounded by the claval suture until just 

 before the apex of clavus, when it crosses the suture and extends as a 

 gradually narrowing stripe around to the tij) of the wing, corium 

 greenish on basal j^ortion, hyaline beyond. Eyes reddish, propleura 

 unmarked. 



Described from one male and seven females from Ames, Iowa, and 

 one female from the Van Duzee Collection (Colden, N. Y.) 



Larv^ similar in form to those o{ ferruginoides, head very broad, 

 transverse or slightly rounding; eyes prominent, thorax btout, convex ; 

 abdomen short, broad, dorsally carinate. 



Color, green, a black stripe arising behind either eye as in the adult, 

 but running back across the wing pads and along the abdomen just 

 within the margin, widest near the end of the wing pads, where it 

 curves out and becomes narrower on the abdomen. 



The larvae appear on willows about the first of June and even then 

 show the unmistakable black line; adults from the first of July on 

 into August. 



Readily distinguished from other described species by its black 

 dorsal shield. It might be mistaken for basalis, with the basal mark 

 elongated, but for its sharp vertex. 



Pediopsis gleditschi^ n. sp. 



Form and color of viridis nearly, about one-third smaller, with a 

 slightly shorter, rounder vertex, approaching reversalis in size but much
