XEW EECOEDS & SPECIES OF MALAYAN MEMBEACEDAE. 225 



Undersuri'ace of body entirely black: sides of metathorax thick- 

 ly white tomentose: legs uniformly dark brown. 



Length 3.4 mm. : width between tips of humeral angles 1.7 mm. 



Type : female. 



Locality: Sandakan. Borneo. 



Unique type in Professor Baker's collection. 



In erecting the genus Parayasa, Distant gives as one of the 

 generic characters the position of the ocelli as about equidistant 

 from each other and from the eyes. This is certainly not the case 

 in the species here described, although I believe it unquestionably 

 belongs to the genus as designated. I think, also, that the f act- 

 that the scutellum is not exposed in the insects of this genus should 

 be stated as an aid to identification.
