Fowler places it as a synonym of bifascia, along with 

 angusta. The latter was described, from Georgia and is an 

 undoubted, synonym of ^bicincta, and. if Fowler is correct in 

 uniting the three forms, as it seems, then all four species fall 

 as synonyms of bicincta. 



" SUBFAMILY APHROPHORIN^ Stal. 



In this subfamily the species are smaller, more elongate, 

 and, as a rule, rather somber colored. The group is well 

 represented in our territory in both genera and species. Two 

 of the species are European and probably introduced, while 

 many of them are widely distributed, and several extend . 

 beyond our borders to the southward. 



SYNOPSIS OF THE GENERA. 



A. Apex of clavus acute, cQrium without a terminal membrane. 



B. Anterior margin of the pronotum angulate, ocelli nearer each 

 other than eyes; rostrum long; exceeding the hind coxa?, with 

 three visible segments, the terminal one much the longest. . 



Aphrophora Germ. 

 BB. Anterior margin of pronotum rounded, ocelli nearly equally dis- 

 tant from eyes and each other: rostrum short, not exceeding 

 middle coxae; composed of two equal visible segments. 

 C. Anterior margin of vertex between front and eyes sharp; 

 whole upper surface densely pubescent, almost hiding 

 sculpturing and venation: submarginal vein of wing 

 interrupted between second and third sectors. 



Lepyronia A. & S.C' 

 CC. Anterior margin of vertex between front and eyes sulcate. 



D. Elytra irregularly reticuled apically. Philaronia n. g.O 

 DD. Elytra with about five apical cells. Phikenus Stal.^? 



A A. Apex of clavus broadly rounded, corium with a broad terminal 

 membrane; submarginal vein of wing interrupted at apex. (Small 

 globose forms. ) *Clastoptera Germ . !> 



GENUS APHROPHORA Germ. 

 Vertex obtuse or rectangulate, the apex rounding, anterior margin 

 between the eyes and tylus sharp, ocelli placed close to the posterior 

 margin, nearly twice farther from the eyes than from each other; head 

 with the eyes scarcely as wide as the posterior angles of the pronotum, the 

 anterior and posterior margins nearly parallel, the latter with a median 

 triangular notch between the ocelli, into which fits a slight projection of 

 the pronotum; front convex, inflated, transversely wrinkled except on the 

 median line; rostrum long, with three visible segments, the last one much 

 the longest, extending beyond the hind coxae; pronotum large, about one- 

 half longer than;the vertex, anterior margin distinctly angulate, medially 

 produced into the notched vertex; a distinct median carina extending
