SYSTEMATIC ARRANGEMENT. 
This beautiful Cicada (which Mr. Westwood, to 
whom we have been indebted for a drawing, con- 
siders as forming a distinct subgenus, in consequence 
of the numerous veins with which the anterior wings 
are furnished) formed part of the late General Hard- 
wicke’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, Fahr. 
C. speciosa, Illiger, &c., but differs considerably from 
these and every other described species.

This is the largest of the European Cicadse, being 
frequently found to measure two inches in length, and 
4 1 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.
