Tettig. villosa Fabr.. (C. G. Hope.) 
These various genera are entirely established upon external cha- 
racters, especially the relative size and form of the head, prothorax, 
and sonorous organs; and, as most of the types of these groups are 
well known species, I have not thought it necessary to detail their 
characters. 
The two species of Cicada, represented in the accompanying plate, 
appear to enter into M. Serville’s genus Gzeana; the fore-wings 
being entirely opaque (Syn. art. 720), the sides of the prothorax not 
dilated (art. 726), and the front of the head rounded (art. 727.) 
There is,however, considerable diversity between these two species 
in the comparative breadth of the wings. 
CICADA PULCHELLA, Westw. (Puare 57, fig. 1. 9) 
(Royle’s Himalaya, pl. 10, fig. 2.) 
Nigra capite thoraceque sulphureo-maculatis, alarum dimidio basali sulphureo (in alis anticis 
fascia nigricanti obliqua diviso) apicibus flavido-fuscis, venis in partibus obscuris nigris. 
Expans. alar. unc. 33. 
Habitat in Himalaya, &e. Mus. nostr. &c. 3, 9. 
The abdomen beneath and on each side at the extremity is 
spotted with yellow, the fore-wings are broadly wrinkled as in C. 
maculata, and the drum-covers of the male are small, leaving the 
striated internal membrane broadly exposed. 
CICADA 8-NOTATA, Westw. (Puate 57, fig. 2.9) 
Nigra, capite fascia frontali et postica, fasciaque postica prothoracis metathoraceque flavidis, 
mesothorace lineis duabus irregularibus flavidis, abdomine sanguineo segmentis basalibus 
supra in medio nigro maculatis; alis anticis fusco-nigricantibus, singula maculis 4 
albidis venisque tenuissimis rubris ; alis posticis sanguineis nigro-limbatis. 
Long. corp. lin. 113. Expans. alar. une. 2, lin. 7. 
Habitat in Assam. Mus. Westw. ¢, 2. 
I am indebted to Mr. Robinson for this interesting novelty, 
which is closely allied to C. dives W. figured in pl. 25 of this work, 
from Sylhet. Like that species, the present has rather narrow 
fore-wings, which have the surface very closely wrinkled with 
transverse furrows.
