maculate or nearly so. Elytra dusky hyaline, ner\-ures pale yellow, distinct. 

 Wings whitish hyaline, nervures brown. Abdomen black; connexivum, 

 genital pieces, last ventral segment and sometimes the disc of the two or three 

 preceding segments, yellow in the male. The female has these yellow mark- 

 ings on the abdomen more extended, in some examples replacing the black 

 entirely on the venter, and the ovipositor black; otherwise like the male. 



Described from ten examples, representing both sexes, taken 

 at Buffalo, Lancaster and Colden, N. Y., and Welland County, 

 Ontario, from July 4th to September loth, and one example from 

 New Jersey (J. B. Smith). In the National Museum is an example 

 of this species labeled Jassiis ^-punciaius Fitch MS. , but as this name 

 is pre-occupied for an European form I ha\'e substituted for it the 

 one here adopted. 



This species somewhat resembles Cicadida nigrifrons Forbes, 

 but the head is more strongly angled before, and the elytral vena- 

 tion and the form of the genital pieces is different. From T. nie- 

 lanogaster it may be distinguished by its smaller size and by the 

 position of the black spots on the vertex, which are not placed on 

 the edge as in that species, but on the superior surface adjoining the 

 anterior margin. 



Athysanus striatulus Fall.?— In form similar to Cicadiila exitiosa Uhl., 

 but with the elytra a little wider at tip. Pale testaceous, marked with black 

 on the head, pronotum and scutellum. Elytra pale testaceous, nervures 

 more or less broadly margined with blackish; apical areoles smoky. Length 

 3 — 4 mm. 



Head wider than the pronotum, closely and finely punctured. Vertex 

 obtusely triangular, apex rounded, its length on the median line subequal to 

 that of the scutellum and about one-half the width on the hind margin be- 

 tween the eyes; passage to the front rounded, but less so than in exitiosa. 

 Front wide, abruptly narrowed to the broad apex. Clypeus broad, quad- 

 rangular, not narrowed to the tip, length one and a half times the breadth, 

 margins rectilinear; lorse large, ovate. Cheeks broad, strongly angled below 

 the eyes, forming a broad border beyond the lorae, but not surpassing the 

 clypeus. Pronotum finely punctured, obscurely transversely wrinkled and 

 slightly depressed across the disc; hind edge feebly concave. 



Ultimate ventral segment of the male a little longer than the preceding, 

 with which it agrees in form; valve broad, convex, obtusely rounded at apex; 

 plates triangular, their margin fringed with coarse white bristles, within which 

 are three or four short, stout spines, suture depressed. Hind margin of the 

 penultimate ventral segment of the female feebly concave, in some examples 

 forming an indistinct, re-entrant angle, disc with a longitudinal carina; margin 

 of the ultimate segment quite strongly arcuated each side, leaving a rounded 

 central lobe; pygofers rather broad, apex truncate and slightly exceeded by 

 the ovipositor, armed with irregular stout bristles. 



Male: Pale, or testaceous yellow. X'ertex with an impressed line and 

 three narrow transverse bands piceous black, the posterior angled near each
