Hah. Ceylon; Weligama {Green), Newara - EHa {f^de Mot- 

 sclioidslcy). 



Mr. Green has sent me four specimens of this species which 

 agree with the description of Motschoulsky {supra). The two 

 black spots which he describes as on the mesonotum I regard as 

 on the base of the scutellum. 



2685. Typhlocyba sudra, sp. u. 



Pale greyish with a flavescent tint, in some specimens dull 

 virescent ; vertex with an apical black spot which is visible 

 beneath on the basal margin of face ; eyes black ; scutellum with 

 two prominent black spots near the . basal angles ; tegmina 

 subhyaline tinged with flavescent or virescent ; wings hyaline, 

 somewhat strongly iridescent ; vertex rounded in front, shorter 

 than breadth between the eyes ; scutellum transversely impressed 

 near middle. Allied to nvjrobimacidata, Motsch., but with vertex 

 a little longer and slightly more angulate, and also distinguished 

 by the apical black spot. 



Length 2| to 3 miUim. 



Hah. Calcutta {Annandah). 



Breeds on the leaves of Bauhhiia acuminata., on which it is very
