The opercula are broad, convex and overlapping ; the face has a faint central longitudinal sulcation, and the rostrum extends to the posterior coxfe.
Var. a. — Differing from typical specimens by having the abdomen above ornamented by a transverse fascia of white pile situate immediately behind the tympana and widened at the lateral margins ; the abdomen beneath is also more or less thickly covered with white pilosity. The opercula in this variety are also totally black.
Var. b. — In this variety the ground colour is ochraceous, and not greenish-ochraceous ; the black markings to the head, pronotum and mesonotum are also much larger and more or less confluent ; the

Allied to P. maculaticollis, Motsch., but differing from that species by the darker and more obscure hue of the body, the distinctly pale fuscous tegmina and wings, and by the length of the rostrum, which considerably passes the posterior coxne and terminates on the overlapping opercula. The head is also much narrower than in P. macidaticollis, and the opercula are unicolorous and more broadly and regularly convex posteriorly.

Head broad, more or less transversely truncate between the eyes, and including the eyes a little broader than the base of the mesonotum ; ocelli about twice the distance from eyes as from each other; face slightly prominent above, moderately tumid and convex beneath. Pronotum with the lateral margins slightly ampliated, but not augulated or toothed. Anterior femora distinctly and strongly spined.

short, or in other species nearly as long as the abdomen, and in shape either convex, rectangular or more or less acutely angulated. Tegmina with the basal cell longer, but not twice as long as broad. The geographical distribution of this genus is comprised by the hmits of the fauna treated in this monograph which thus includes all the recorded species.
CnjptoUjmpana is a very distinct genus in the Oriental Cicadidae, the large size of its species and their usually sombre coloration at once attracting attention, while the metasternal process is an unfailing generic characteristic.
Its nearest ally is the American genus Fidiciim, in which Walker placed the species he described.
