( 335 ) XIV. Descriptions of neiv species and a new genus of Cicadidae from Madagascar. By W. L. Distant. . [Read June 7th, 1882.] Plate XV. The more we see of the Ehynclibtal fauna of Madagascar the greater is the amount of structural speciahsation apparent, and its distinct character revealed. This is particularly the case with the Cicadidae, and every species of the widely distributed Genus Platypleura which has yet been received from Madagascar has proved new to Science. I have added the description of another species here, and also of a new genus possessing an inflated abdomen, a character found in genera distributed in South Africa, Australia, and Polynesia. Platypleura jmlverea, n. s. (PL XV., figs. 1, la, Ih). Body above ochraceous. Head with a black spot in centre of front, and with a marginal black line ; its vertex with the following black markings : — a transverse band near each anterior angle, a waved transverse fascia between the eyes, widened at ocelli and surrounding the same in the shape of a subquadrate spot, on each side of posterior margin of which is a linear streak followed by a rounded spot and with an irregularly shaped spot on the inner margin of the eyes. Pronotum with the following black markings : — an acutely angled fascia on each side of disk, the inner line of which has a trans-verse base, a small arcuate spot beneath this, two oblique lateral fasciae, and two rounded contiguous spots on centre of inner border of posterior margin. Mesonotum with the following black markings : — two short obconical spots on anterior margin, the apices of which are dentate, beneath these a central triangular spot followed bv two round spots, and on each side an oblique sub-marginal fascia.
