which approximate in the middle ; three blackish streaks on each side, where there is an acute angle in 

 IVont. Mesothorax with a black middle stripe, and with five black streaks on each side. Pectus with four 

 lilack spots. Abdomen partly black beneath towards the tiiD. Wings vitreous ; veins testaceous, black 

 towards the tips. Fore wings with a whitish stigma : tips and transverse veins, and tips of the marginal 

 veins clouded with brown."

Hab. — BuEMA (Brit.jMus.). Borneo: Sarawak (coU.Dist.) ; Philii^pine Islands (Semper — Stockh.Mus.). 



I include this species ? with considerable hesitation. Walker described it from a 

 single female specimen, — a most unsatisfactory proceeding, — and I have only seen another 

 specimen, and that of the same sex. Stal, who had visited the British Museum and inspected 

 Walker's types, apparently had no reticence in identifying some Philippine specimens as 

 L. guttidaris, and, having male examples, writes, " L. tuherosce, Sign., simillima, divergit 

 operculis obtusioribus, apice multo minus oblique truncatis, parte apicali exteriore obtusiore, 

 minus longe producta, tuberculisque ventris apud marem majoribus nigris, lobum tumidum 

 simulantibus." The female type, to my view, is closely allied to L. alhiguttata, Walk., and 

 may possibly yet prove to be simply that species. 



Genus DUNDUBIA. 



DunduLia, Amyot & Serville, Hist, des Hem. p. 470, 871 (1843) ; Still, Hem. Afr. iv. p. 5 (18G6) ; Atkins. 

 J. A. S. Beng. vol. liii. p. 223 (1885); ibid. vol. Iv. p. 157 (1886). 



Body robust, long. Head somewhat triangularly elongate, including the eyes rather narrower than 

 base of pronotum at lateral angles ; ocelli a little farther apart from eyes than from each other ; front large, 

 globular, and convex, about twice as broad at base as the anterior lateral margins of the vertex. Pronotum 

 with the margins not prominently ampliated, but distinctly toothed. Anterior femora spined. Tympana 

 covered ; opercula long and extending beyond the middle of the abdomen. Piostrum scarcely reaching the 

 posterior coxae. Tegmina hyaline, the basal cell twice as long as broad ; interior ulnar area with the 

 apex not or very slightly ampliated. 



The absence of the tubercle or tumescence to the genas and of the tubercles to the second and thu'd 

 abdominal segments of the male, together with the presence of the long opercula and the large, globular 

 and convex front and face, sufficiently distinguish Dunduhia from the preceding genus, Leptopsaltria. 



This genus is a small one, though, owing to the number of species described uniformly 

 by Walker imder the generic name Dunduhia, it would appear to be the largest genus of 

 the Oriental Cicadidce. 



In geographical distribution, Dunduhia is strictly confined to our faunistic area, and is 

 focussed in the Indo-Malayan region ; it is doubtful whether it extends so far eastward as New 

 Guinea, but our collections from that large island are still too small to enable us to speak 

 positively as to its absence. Its distribution, however, throughout the Malayan Archipelago 

 is in no way equal to that of the following and allied genus Cosmopsaltria. 



Another feature in the general appearance of the species of this genus is the unspotted 

 tegmina, no species of which the writer is cognisant having the transverse veins at the bases 

 of the upper apical areas infuscated.
