Bright green. Vertex pale yellow, narrowly lined with 
black, acutely triangular, longer than the pronotum. 
Length, 9 7.5 mm., $ 6 mm.; width, 1.5 mm. 
Vertex acutely angular, produced, disc flat or concave, margin 
straight, somewhat variable in length, always distinctly longer 
than the pronotum, in the female, slightly longer or almost equal- 
ing it in the male. Face long, retreating in an acute angle, in pro- 
file straight to the clypeus which is transversely inflated and angled 
slightly with the front. Elytra long, coarsely reticulate from apex 
back to the forking of the outer branch of the first sector, nervures 
raised, distinct. 
Color; vertex, straw yellow, eyes, ocelli, a median line, a pair of 
posteriorly divergent lines on the disc, three concentric arcs on 
reflexed portion of front on each side and a pair of dots at apex, 
fuscous. Anterior part of pronotum and scutellum pale green to

ica, and Walker’s innotata , the identification of which is in 
doubt, was from Brazil.
