forming a very slight median tooth; male plates very short, bluntly 

 triangular, not as long as ihe ultimate segment, less than half the 

 length of the pygofers. 



Specimens are at hand from southern Ohio, a pair each 

 from southern Illinois, Florida and Mississippi, and several 

 females from Texas, New Mexico and Cuba. The speci- 

 mens from New Mexico and Cuba have the elytra very 

 dark, with the light nervures in sharp contrast. 



Genus Heloch.\ra, Fitch. 



Similar to-Tettigojiia in form, head wider than thorax, much 

 broader than long, slightly conical, slightly obtusely angled, retiexed 

 portions of front elevated, prominent. Face well rounded back, 

 profile convex. Pronotum very long, sexangular, resembling Aula- 

 c-/2r<?5, lateral margins short, humeral margins very long, the humeral 

 angles rounding to the short medially emarginate posterior margin. 

 Scutellum very small, covered almost to the transverse suture by 

 the pronotum. Elytra coriaceous, veins distinct, raised; venation 

 simple, regular; three auteapical cells and five apical ones. Male 

 antennae with the apical third developed into a flat plate.

\) 



Small, robust, deep green, superficially resembling reticu- 

 lata or the mnleoivwllipes Vciv.,mi)ior. Length, 9 6 — 7 mm.; 

 <?4 — 5.5 mm.; width, 1.25 mm. 



Vertex a trifle less than two-thirds the length of the pronotum 

 roundly, obtusely angled, the margin blunt, reflexed portion ot front 

 prominent, striated. Front sloping well backwards, outline convex 

 or slightly angled above the middle, again on clypeus. Pronotum 

 very long, deeply angled behind. Scutellum very small, less than 

 half the length of the pronotum. Elytra coriaceous except at apex, 

 venation regular, the anteapical cells almost parallel margined. 

 Whole dorsal surface microscopically pustulate. 



Color deep green, often fading to pale yellowish olive, except for 

 stripes along the clival suture. The eyes ocelli frontal suture and 

 about four concentric lines on the reflexed portions of front dark. 

 Face and below, pale olive, with about nine dark arcs on front in 

 the female, front usually black in the male. 



Genitalia; female segment but little longer than the penultimate, 

 broad and flat, the posterior margin slightly produced in the mid- 

 dle. Male valve broad and short, plates finger-like, triangular, very 

 slightly longer than the ultimate segment. 



Specimens are at hand from Ontario, Vermont. New 

 York, District of Columbia, Virginia, Ohio, Tennessee,
