Prosternum and prothoracic episterna with fairly long yellowish-white hairs; sensory pit below prothoracic spiracle bare, not guarded by hairs.
Occiput and postocular portions of genae, pronotum (except lower portions of lateral lobes), tegmina and all other portions of body shining blackish-brown (except whitish markings on episterna described above and last two sternites of females which are greenish); tegminal pads do not surpass the second abdominal tergite.
Ventral margins of metathoracic episterna and epimera slightly produced and outwardly flared.
While in the green form genae and lateral lobes of the pronotum are apple-green, the latter narrowly fringed with white on their lower margin, in the cinnamon form, genae and lateral lobes of pronotum are marked with two or more tenuous longitudinal fuscous bands, not seen in green specimens; the lower part of the genae in these cinnamon specimens is cream-color (54); of this same color are wide bands along lower parts of lateral lobes, that continue on mesothoracic episterna. Fore and middle legs are of the prevalent body color; in the cinnamon form they are brownish, including the tarsi: hind femora are colored like the body, hind tibiae in all specimens have black bases, the rest of the tibiae and the tarsi are purple (101).
