This beautiful Cicada (which Mr. Westwood, to whom we have been indebted for a drawing, considers as forming a distinct subgenus, in consequence of the numerous veins with which the anterior wings are furnished) formed part of the late General Hardwicke's collection made in Nepaul, and presented to the Linnean Society of London. It does not seem to exist in any other collection, either in this country or on the Continent. It is allied to C. fasciata, Fabr. C. speciosa, Illiger, &c., but differs considerably from these and every other described species.

This is the largest of the European Cicadæ, being frequently found to measure two inches in length, and 4½ inches between the tips of the wings. The general colour is black, with a yellow line on each side of the thorax, and various smaller stripes of the same colour on different parts of the surface. Underside testaceous-yellow; tegmina and wings transparent. The sound it produces is very loud and shrill. It is first met with on going southwards, in the central provinces of France, and is not unfrequent in many of the southern parts of Europe.
