Cicada flavipennis, Zett., Ins., Lapp., p. 292.

It is not likely to be confounded with anything ex^cQ^iJlavescens, 
Tab., and apicalis, Flor ; both which species differ in having the abdo- 
men wholly yellow. In marshy places, not very common. 
4. — Eupteryx viridulm, Fall. 
Totus loete viridis, capite et pronoto obsolete albo striatis. Oculi 
fusci. Hemelytra pellucida, viridia, immaculata. Alfe hyalinse, nervis 
inconspicuis. ^ $ . Long. 1\ ; alar. exp. 3 lin. 
Cicada viridula, Fall., Hem., Pt. 2, p. 53.

Etipf. solani, Curt., in the Gardener's Chronicle, 1846, p. 388, 
and in Morton's Cyclop, of Agriculture, vol. 1, p. 772, fig. 
This is the " potato frog-fly" of Curtis, stated (1. c.) to have appeared 
in great profusion on that plant after the murrain of 1845. A case of 
post but not propter. It is common, frequently abundant, everywhere, 
in gardens, hedges, and fields, on many other plants beside the Solanum. 
5. — Eupteryx smaragdulus. Fall. 
Viridis ; vertex, pronotum, scutellum, fusco bilineata. Vertex 
brevis, latus, medio non longior quam lateribus. Hemelytra aureo- 
viridia; corium extus, clavus totus vel margine interiore, infuscata. 
Frontis latera, pedes plus minus, cum oviductu feminre, cajrulea. Abdo- 
men supra medio interdum nigricans. Alarum nervi fusci, conspicui.

The fuscous markings vary in intensity, and are frequently absent, 
probably in immature specimens. The short, broad vertex, greater 
size, and different habitat, at once distinguish it from the preceding. 
On willows and alders, common.
