80 ORIENTAL CICADID.E. 



This species being only known to the writer by the type in the British Museum (of which 

 a figure is here given), the original description is also copied : — 



" Nigra; tegminibus a basi vix ad medium subolivaceo-flavis ; alis ultra medium lutescentibus 3' . 



" Statura G. maculata. Frons valde tumida. Thorax antice capita nonnihil angustior, lateribus ab 

 apice ad medium parallelis, deiii subito ampliatis. Tegmina costa et vena subcostali per totam loiigi- 

 tudinem sat distantibus, venis ulnaribus basi sat distantibus, areis apicalibus longissimis, prima, quarta et 

 sexta jequilougis. Opercula subtriangularia, apice rotundata. 



"Long. 42, exp. tegm., 112 mill." 



Hab.— Malay Peninsula : Tringanu (Brit. Mus.) ; Jelebu (Eaffles Mus. Singapore). 



Stal described this species from an unset specimen. I have to thank the authorities of 

 the Zoological Department of the British Museum for having the tegmina and wings expanded, 

 thus exhibiting the tympanal coverings, which show it to belong to the genus Tosena, and not 

 to Gceana. 



e. Tegmina and wings partly hyaline, wings broadly greenish at base, 

 8. Tosena splendida. (Tab. II., fig. 6, a, b, var.)

 Atkins. J. A. S. Beng. voL hii. p. 217, n. 21 (1885); ibid. voL Iv. p. 152, n. 19 (1886). 



Body above black ; front with a reddish spot at each basal angle ; eyes, two small spots on vertex, 

 four large spots to pronotum (two on disk and one at each posterior lateral angle) and two spots on disk 

 of mesouotum,* luteous. Body beneath and legs black; lateral margins of the face, a wide central 

 anuulation to femora, and a central discal series of subtriangular spots, sanguineous. 



Tegmina and wings— where not obscured by darker markings— pale hyaline, exhibiting varied opaline 

 lustre, which in some lights is found to be ornamented with close and regular series of transverse 

 darker strife ; tegmina at base (narrowly) and costal membrane shining blackish ; venation bright luteous 

 and for two-thirds from base broadly margined with shining blackish, and a series of shining blackish 

 margmal spots on the apices of longitudinal veins to apical areas largest and somewhat fused at apex ; 

 claval area pale greenish. Wings pale greenish for nearly two-thirds their area fi-om base ; remaining 

 apical area shining blackish, enclosing a submarginal series of pale opaline spots, of which the largest 

 are subapical. 



Var. a. — Typical, as described above (Waterh. Aid Ident. Ins. t. 147, f. 1). 



Var. b. Supra (Tab. II., fig. 6). 



In this variety all the markings are paler and more sombre in hue, the mesonotal spots practically 

 absent, and the dark fuscous markings to tegmina and wings, not shining blackish. 



Long. excl. tegm. 3^ , 45 to 47 millim. ; ? , 44 millim. Exp. tegm. <? & S , 122 to 127 millim. 



Hab.— Continental India : Naga Hills, 2000 to 6000 ft. (Chennell— coll. Dist.) ; Khasi Hills, 4500 

 to 6000 ft. (Chennell— coll. Dist.) ; Lushai Country (Calc. Mus.). Burma : Akyab (coll. Dist.). 



When first diagnosing this species, with only one of each sex before me, I was disposed 

 to consider that the sexes usually differed in the manner there described. I have, however, 

 since received other specimens, which prove the dark coloration to be the normal form of the 

 species. 



=•= The specimen figured was somewhat faded, but the colorist has altogether ignored these spots.
