42 ORIENTAL CICADIBM. 



anterior lateral angles of vertex ; eyes brownish ; ijrouotum with a narrow, black, lateral marginal fascia ; 

 body beneath and legs ochraceous, apices of posterior tibise infuscated. 



Tegmina and wings pale hyaline, the venation pale greenish ochraceous. 



The rostrum reaches the intermediate coxae ; the opercula are very narrow, slightly curved outwardly, 

 concave on each side near base, the apex broadly convex and extending to about half the length of 

 the abdomen. 



$ . Abdomen with a lateral marginal black fascia on each side. 



Long. excl. tegm. <? , 26 millim. Exp. tegm. 7'2 milHin. 



Hab. — Continental India: Karwar (Atkmson — Calc. Mus.) ; Neelgiri Hills, southern slopes, 

 8000 feet (Hampson— coll. Dist.). 



B. emanatura is another distinctly-marked species, the black lateral margin to the pronotum 

 and the narrow opercula being good differential characters. 



This does not appear to be an abundant species. For some time I possessed only a 

 female specimen sent me, by my good friend Mr. Hampson, from the Neelgiri Hills, but 

 eventually I also obtained the loan of a single male specimen, collected at Karwar, belonging 

 to Mr. Atkinson, and was thus enabled to describe it. 



6. Dundubia? aerata. (Tab. VI., fig. 7, a, h.) 



Dunduhia arata, Distant, Ann. & Mag. Nat. Hist. ser. 6, vol. i. p. 292 (1888). 



Body above resembling D. mannifera, Linn., but much larger; beneath with the opercula small, 

 narrow, concavely sinuated towards the middle, their apices obtusely rounded and reaching the third 

 abdominal segment (rostrum mutilated).* 



Tegmina and wings pale hyaline, their apical areas (especially those of tegmina) suffused with 

 bronzy brown. 



Long. excl. tegm. 50 millim. Exp. tegm. 120 millim. 



Hab. — Borneo: Elopura (Fryer — coll. Dist.). 



This is the largest species of the genus ? at present known to science, and a distinctive colour 

 peculiarity is the bronzy suffusion on the apical areas of the wings and tegmina, especially on 

 the last. 



I am indebted to Mr. W. B. Pryer for a single male specimen. 



b. Opercula narnnv and eloiujate, their ajnces acutely pointed. 



7. Dundubia intemerata. (Tab. IV., fig. 1, a, h.) 



Dundubia intemerata. Walker, Journ. Linn. Soc, Zool. vol. i. p. 84, n. 5 (1856) ; Atkins. J. A. S. Beng. 

 vol. liii. p. 224, n. 42 (1885). 



Body above green, ochraceous, or with the abdomen alone ochraceous. Ocelli red, eyes dark 

 castaneous or fuscous. Rostrum, cosas, tarsi and apices of tibiae ochraceous ; apex of rostrum and 

 the tarsal claws black. 



Tegmina and wings pale hyaline; extreme bases, venation and costal membrane of the first 

 greenish-ochraceous. 



The opercula are elongate and narrow, their apices acutely pointed, and their outer margins strongly 

 and concavely sinuate. 



In this species the rostrum about reaches the posterior coxae, thus nearly affording a character 

 belonging to the succeeding genus CosinopsaUria, but the structure of the head, combined with the 

 unspotted tegmina, locate its position in the genus Dundubia. 



* Possessing but one specimen of this species, I have been compelled to anticipate the length of the rostrum, in order 

 to place it in either the genera DuyidtMa or Cosmopsaltria, to which it undoubtedly belongs. From other characters, I have 

 thought it to belong to the first-named genus, but mo*e specimens are necessary for exact generic determination.
