darker green, propleura unmarked in either sex. Length, ,? 4-5-5 

 mm.; width, 1.25 mm.; cj' slightly smaller, darker. 



Head compact, eyes small, a line across their centers cutting off less 

 than one-third of the pronotum, vertex slightly, roundingly, obtusely 

 angled, distinctly shorter than in viridis. Pronotum very finely gran- 

 ulated, posterior margin angularly excavated, disc strongly convex, 

 depressed within and behind either eye, elytra moderately long, 

 broadly and evenly rounded behivxd. 



Color: Females, bright-green, the el\tra hyaline at the tip; males, 

 the head and pronotum green, the elytra clouded with brownish or 

 dark fuscous, the costal margin green, scutellum yellowish or clouded 

 with fuscous in the darker examples. Below, green in both sexes, the 

 propleura without a black spot in either sex. 



Described from numerous examples. 



Larvae very similar to viridis, short and stout, with transverse heads, 

 thorax convex, shiny, abdomen broad, crested, each segment of the 

 crest elevated into a flat curved tooth projecting backward and tipped 

 with a hair; color, bright green. 



Found exclusively on the honey locust along with Macropsis, the 

 larvae appearing in May and maturing before the middle of June, the 

 adults throughout June and the first half of July. They are found at 

 the base along the sides of the leaf stalks. This species might easily 

 be confused with viridis, but the female is only as large as the viridis 

 male while the males are still smaller and lack the spot on the pro- 

 pleura. Deeply-colored males have the elytra almost black instead of 

 brown, as in viridis. These characters, along with the very distinct 

 and constant difference in food plant and life history, leave no ques- 

 tion as to specific identity. 



Pediopsis crocea n. sp., {^gleditschia ? var.) 



Form of basalis nearly, smaller, with short, stout elytra which are 

 scarcely longer than the abdomen and are inclined to be flaring be- 

 hind as in trisiis; bright saffron yellow, the elytra clouded with brown. 

 Length, 5 5 mm.; width, 1.5 mm.; males smaller. 



Head short, depressed, the pronotum very much elevated behind, 

 the anterior margin depressed, obtusely angled before, the rugje coarse 

 and distinct, a median raised line. Scutellum very coarsely rugose, a 

 triangular spot in each basal angle shagreened. Elytra strong, nerv- 

 ures distinct, lighter.
