forming a very slight median tooth; male plates very short, bluntly 
triangular, not as long as the 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 Helochara, Fitch. 
Similar to Tettigonia in form, bead wider than thorax, much 
broader than long, slightly conical, slightly obtusely angled, reliexed 
portions of front elevated, prominent. Face well rounded back, 
profile convex. Pronotum very long, sexangular, resembling Aula- 
cizes, 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 anteapical 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 male of mollijjes var., minor. Length, $ 6 — 7 mm. ; 
$i — 5.5 mm.; width, 1.25 mm. 
Vertex a trifle less than two-thirds the length of the pronotum

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

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 ^,long the claval suture. The eyes ocelli frontal suture and 
about four concentric lines on the reflexed portions of front dark. 
Pace and below, pale olive, with about nine dark arcs on front in
