Tegmina with basal half opaque, greenish-ochraceous ; two fuscous spots on costal membrane, two in 

 radial area enclosing a semihyaline spot, a spot of the same colour beneath apes of radial area enclosing 

 two very small semihyaline spots and a large irregular transverse fuscous fascia crossing tegmina beyond 

 radial area, enclosing two semihyaline spots situate in the third and fourth ulnar areas, and another 

 similar spot situate in the lower apical area; remaining area of tegmina hyaline, with the venation 

 greenish-ochraceous, and a large fuscous subapical fasciate spot extending across the apices of the first, second 

 and third ulnar areas, stretching outwardly across the third and fourth apical areas and then continued to 

 apex, and a double series of small fuscous irregular-shaped spots on and near the apices of the longitudinal 

 veins to apical areas. Wings opaque, ochraceous, the apical area and apex of anal area dark castaneous, 

 outer margin pale hyaline. 



The rostrum just passes the inner angles of the opercula, which slightly overlap and are outwardly 

 convex.*

This species has ahvays been found in every collection of Gicadidce examined by the 

 writer that has been derived from the North-Eastern Provinces of Continental India, to which 

 and Burma, its head-quarters at least appear to be confined. The variety, t—«ssflmcns«s, 

 Atkins., — has also been found in most of the cohections where the species was represented by 

 a fair number of specimens.

Head, pronotum, and mesonotum dull ochraceous ; head with the following black markings :— a narrow 

 transverse fascia on front, a transverse fascia between eyes, forming a spot at area of ocelli, continued on 

 inner margin of eyes, two small discal spots, and a fasciate spot at anterior lateral angles of vertex; 

 pronotum with a central longitudinal fascia widened anteriorly and posteriorly, the oblique furrows and the 

 lateral dilated margins black ; mesonotum with four obconical spots on anterior margin (the central ones 



=:= I have^felt it superfluous to describe very fully in words the structural differential characters of the face, rostnim, and 

 opercula, havuig given diagrams of the same, which are more useful and explanatory. 



+ In treating other entomologists' " species " as " varieties," I am, of course, — in the absence of breeding experiments, — 

 expressmg my own views alone, ou the basis of reasons already given (antca, p. 3). The value of these specific discussions 

 has long smce been exposed by Darwin. 



I Named after E. Ksmpfer, physician, naturalist, and zoological traveller. He travelled in Persia and various parts of 

 India; but is best known by his ' History of Japan,' which was translated from the original High Dutch by Scheuchzer, and 

 published m two foho volumes in 1728. Ksempfer was born in IGol and died in 1713.
