Type, /. ravana, Kirby. 



Distribution. Ceylon. 



Head triangular, subiiorizoiital, with a central narrow longi- 

 tudinal impressed line or suloation, eyes well separated from 

 anterior margin of pronotum ; rostrum reaching apex of posterior 

 coxae ; antenuae moderately long and slender, second joint slightly 

 more than twice as long as tirsfc and distinctly thickened at apical 

 area, basal joint slightly thickened, eyes distinctly separated from 

 anterior margin of pronotum ; pronotum with the basal at least 

 twice as broad as anterior margin, with a central longitudinal 

 sulcation, and two transverse impressions, one immediately 

 behind anterior margin, the other before middle, lateral margins 

 coucavely sinuate, posterior angles subspinously produced, disk 

 transversely rugosely striate ; scutellum moderately tumid ; 

 hemelytra subhyaliue ; legs of moderate length, posterior femora 

 moderately incrassated ; tibiao finely setose. 



Kirkaldy placed this genus in the Capsaria. He had, by the 

 omission in his description, evidently overlooked the central longi- 

 tudinal incision to the head.
