ORIENTAL CICADIDJE. 23 



5. Platypleura badia. (Tab. VII., fig. 15, a, h.) 



PUitijiilcura hadiii, Distant, Ann. Mus. Civ. Genoa, ser. 2a, vol. \-i. p. 153, t. iv. f. G, (i, h (1888). 



$ . Allied to P. insiipiis, Dist., but difYering by the opaque markings to the tegmina being fulvoug- 

 brown ; the wings have the opaque coloration extending further from the base, where it is sunplj' pale 

 fulvous, and the body is fulvous-brown. 



The species, however, is structurally separated by the length of the rostrum, which reaches the base 

 of the anal segment. 



Long. excl. tegm. 16 millim. Exp. tegm. 48 millim. 



Hab. — Tenasseeim: Houngdarau Valley (Pea — Genoa Mus.). 



Genus POLYNEUEA. 



Pohjneiira, Westwood, Arcan. Ent. vol. i. p. 92 (1842) ; Amyot & Serville, Hist, des Hem. p. 460, 856 (1848) ; 

 Still, Hem. Afr. vol. iv. p. 3 (1S6G). 



Body robust and moderately elongate. Head including eyes about equal in width to the mesonotum 

 at base ; ocelli farther apart from ej-es than from each other ; face moderately convex, slightly prominent 

 above. Pronotum with the lateral margins moderately ampliated and somewhat laminately expanded, 

 obscurely and obtusely toothed near centre. Anterior femora distinctly and robustly spined. Meso- and 

 metastcrnums sulcatod. Tympana covered; opercula short, and broad. Tegmina with the venation dense 

 and furcate, reticulate towards apex, ulnar and apical areas numerous and ill defined. 



This geuus is still represented by a solitary species, and its area of distribution is confined 

 to Continental India and Burma. 



1. Polyneura ducalis. (Tab. II., fig. 7, a, b.) 



Volyniura ducalis, Westwood, Arcan. Eut. vol. i. p. 92, t. 24, f . 2 (1842); Amy. A Serv. Hist, des Hem. 

 p. 4G0, n. 1 (1843) ; Walk. List Horn. i. p. 2 (1850) ; Atkins. J. A. S. Beng. vol. liii. p. 211, n. 1 (1S85). 



Body above and beneatli black ; eyes, the anterior lateral margins of vertex, and the anterior and 

 posterior margins of pronotum, ochraceous ; femora reddish, their bases and apices and the tibiae and 

 tarsi black (coxa3 in some specimens also reddish). 



Tegmina brownish-ochraccous, the venation, costal membrane, and claval margin ochraceous ; the 

 tegmina are also darker in hue for a little more than basal third. Wings ochraceous, in some specimens 

 (as in the one here figured) irrorated with paler ochraceous, and the tegmina, as in the same figure, 

 sometimes with a short transverse discal ochraceous fascia. 



The rostrum about reaches the posterior coxa;; the opercula are short, not extending beyond the 

 basal segment of the abdomen, their lateral margins oblique, their posterior margins convex and their 

 inner angles overlapping. 



Long. excl. tegm. 35 to 37 millim. Exp. tegm. 100 to 110 millim. 



Hab. — Continental India ; Nepal (Hardwicke — Hope Mus. Oxford and Brit. Mus. ; North-Western 

 Province, Piauikhet (Calc. Mus. and coll. Dist.) ; Sikkim and Assam (Calc. Mus.) ; Darjecling (Stock. iCus. 

 and coll. Dist.). Burma: Eangoon (coll. Dist.). 



The specimen here figured is a female, which has proved to be the dominant sex in all 

 the examples of the species which have passed through my hands; the females are also, from 

 my measurements, larger than the males.
