On the Hymenoptera collected by Mr. 



Robert Shelford at Sarawak, and 



on the Hymenoptera of the 



Sarawak Museum. 



By P. Cameeon, of New Mills, Deebyshiee. 



This paper is based on material collected at Sarawak, by 

 Mr. Robert Shelford of Cambridge University and on the spe-

 collected by A. R. Wallace, very little has been written on the 

 Bornean species, of which an immense number must still remain 

 to be discovered in all the families, but more particularly among 

 the smaller parasitic tribes— Ichneumonida?, Braconida?, Oxyura 

 and Chalcididae.

 tex and the mesonotum have a slight purple tinge. The cloud 

 on the fore wing occupies all the radial cellule ; the upper half
