ORIENTAL CICADIDM. 109 



Genus TALAINGA. 



Talainga, Distant, Ann. & Mag. Nat. Hist. ser. G, vol. v. p. 100 (1890). 



? . Body somewhat elongate, the abdomen cylindrical. Head with the front globose and prominent, 

 including outer margins of eyes, about as broad as base of mcsonotum ; ocelli about twice as far apart from 

 eyes as from each other. Pronotum with the lateral margins ampliated at posterior lateral margins. 

 Anterior femora robustly spined. Tegmina talc-like, semi-opaque, the whole apical area with the venation 

 reticulate and forming a mass of small cell-like areas ; in some specimens the ulnar areas are also crossed 

 hy transverse veins ; interior ulnar area about the same width at apex as at base ; basal cell about twice as 

 long as broad. Wings with the outer margin deeply sinuate near abdominal area; apical areas six, in 

 some specimens broken up by transverse veins into a more numerous and reticulated series. 



This diagnosis is fountled on two female specimens, the structure of the abdomen 

 implying that the tympana are uncovered in the male sex, and thus locating the genus in 

 the Tibiceniiuv. 



Talainga is allied to Gaana, from which it is at once distinguished by the reticulated 

 tegmina, kc.

Talainga Bitii/haini, Distant, Anu. & Mag. Nat. Hist. ser. G, vol. v. p. 167 (1890). 



S . Body and legs black ; eyes ochraceous, their posterior margins pale sanguineous ; pronotum with 

 the lateral margins and a curved spot on lateral areas behind the eyes pale sanguineous, posterior margin 

 — excepting extreme centre — narrowly ochraceous. Abdomen above with the marginal segments more or 

 less gre^-ishly pilose. 



Tegmina talc-like, semi-opaque, very pale ochraceous, the venation black and margined with the same 

 colour, the whole apical ajea being thus composed of numerous small, black-margined, cellular areas ; the 

 costal membrane ochraceous, the basal coll shaded with black. "Wings pale bluish-green, the venation 

 more or less concolorous, excepting that dcliminating the more or less reticulated apical areas ; posterior 

 margin blackish from apex to the sinuation near abdominal area. 



Long. excl. tegm. 2 , 23 to 26 millim. Exp. tegm. 70 to 77 millim. 



Hab. — Burma : Karen Hills (Bingham — coll. Dist.). 



This beautiful genus is a great acquisition to our knowledge of the Eastern ( 'iauliiltv. The 

 tjrpe of coloration resembles that of Tosena xplriulida, Dist., which is also found in Burma, a 

 country that has produced some of the handsomest insects to be found in the whole family. 

 Burma is still likely to contain many Cicadan novelties. 



Genus GRAPTOTETTIX. 



Graptotcttlr, Stul, Hem. Afr. iv. p. 4 (18CC) ; Atkius. J. A. S. Beng. vol. liii. p. 221 (1885) ; i7././. vol. Iv. 

 p. 15G (188G). 



Body moderately long and robust. Head, including eyes, narrower than the base of mesonotum ; 

 ocelli about equally wide apart from eyes as from each other ; rostrum extending to about the intermediati" 

 coxa;. Pronotum a little narrower in front than behind, the posterior latoral angles ampliated, rounded, 

 and somewhat posteriorly produced. Anterior femora robustly spined. Tympana completely exposed and
