110 ORIENTAL CICADIDM. 



uncovered ; opercula short, broad, and basal. Tegmina more or less opaque ; apical areas usually ten, 

 sometimes only nine ; basal cell much longer than broad. Wings more or less transparent. 



This genus is variable in the number of the apical cells to the tegmina, which were 

 described by Stal as amounting to ten, but in some specimens of G. guttatus in my own 

 collection there are only nine. 



1. Graptotettix guttatus. (Tab. III., figs. 21, a, h.) 



Graptotettix guttatus, Stal, Berl. Ent. Zeit. x. p. 170 (1866) ; Atkins. J. A. S. Bang. vol. liii. p. 221, n. 32 (1885). 



Head, pronotum and mesonotum black ; front of head, oceUi, and two large oblique spots— sometimes 

 fused — on each lateral area of the pronotum, bright ochraceous ; mesonotum with two small central 

 obconical spots and two much larger lateral spots very obscurely ochraceous. Abdomen above dull 

 castaneous, — in some specimens, as the female here figured, — illuminated with ochraceous. Head beneath, 

 sternum and legs black ; face bright ochraceous ; opercula and abdomen castaneous. 



Tegmina opaquely pale fuscous ; the venation, costal membrane and postcostal area brownish- 

 ochraceous ; the base narrowly blackish. Wings bronzy, shining, and semi-opaque. 



Long. excl. tegm. <? , 30 millim. ; S , 27 millim. Exp. tegm. <? and 2 , 70 to 73 millim. 



Hab. — Continental India: Sikkim (Calc. Mus.) ; Naga Hills (coll. Dist.). China* (coll. Signoret). 



T'rtr. a. — Tegmina with pale streaks in the apical areas ; abdomen ochraceous. 

 Hab. — Continental India: Naga Hills (coll. Dist.). 



This species, as above remarked, also varies in the number of the apical cells to the 

 tegmina, which in some cases are only nine. 



2. Graptotettix thoracicus. 



Gi-dptotettLv thoracica, Distant, Auu. & Mag. Nat. Hist. ser. 6, vol. ix. p. 315 (1892). 



S . Head, pronotum and mesonotum bright pale ochraceous ; abdomen pale sanguineous. Eyes 

 fuscous. Pronotum with the posterior, lateral, and anterior (as far as behind eyes only) margins 

 castaneous and with two narrow, jet-black central, discal, curved fasciae. Mesonotum with four pale 

 castaneous obconical fasciiB, the central pair smallest. Abdomen above ochraceous near base. Body 

 beneath and legs sanguineous ; head beneath, anterior coxte and lateral margins of sternum ochraceous ; 

 spots on coxae black. (In the specimen described the apex of one posterior femur and its tibia is almost 

 black ; the other posterior leg is uniformly sanguineous.) 



Tegmina and wings pale hyaline, more or less completely tinged with castaneous (in the specimen 

 described more so on one tegmina and wing than on the other), the venation ochraceous or castaneous. 



Long. excl. tegm. J , 28 millim. Exp. tegm. 75 millim. 



Hab. — Burma: Momeit (Doherty — coll. Dist.). 



This species is distinguished from G. guttatus, Stal, by the totally different colour and 

 markings of the pronotum and the colour of the head ; the front of the head is also more 

 angulated, and the face more angularly tumid. 



■1= This habitat must be taken conditionally. My late friend Dr. Signoret submitted a specimen thus localised to me for 

 identification; but some of his specimens had erroneous habitats, and a late visit to the Museum at Vienna has confirmed that 

 opinion.
