HYMENOPTERA FROM SARAWAK. 87 



the post-scutellum is strongly, but not closely, transversely 

 striated. The median segment has a gradually rounded slope 

 to the apex ; the base and apex are smooth ; the rest coarsely, 

 irregularly transversely striated. Wings uniformly yellowish- 

 hyaline, the apex not infuscated ; if anything paler than the 

 rest of the wing; the stigma and nervures yellowish; the first 

 transverse cubital nervure is obliquely curved ; the upper 

 (longer) part has a more sharply oblique slope than the lower ; 

 the second is straight and oblique; the third is broadly rounded ; 

 the first lecurrent nervure is received near the base of the 

 apical third of the cellule, not close to the second transverse 

 cubital nervure as in Mfgnimia; the first transverse cubital 

 cellule is distinctly longer than the second above, but slightly 

 shorter below ; the second recurrent nervure is received at the 

 apex of the apical fourth of the cellule. Legs uniformly ferru- 

 ginous. Abdomen black ; the last segment rufous all round and 

 thickly covered with long rufous hair ; the penultimate segment 

 is covered with a golden pile. 



This is a much more slenderly built species than S. flavua ; 

 and may be readily separated from it by the cubital cellules 

 being more equal in length, by the pronotum not bulging 

 broadly outwardly in the middle, not narrowed at the apex, by 

 the median segment having a more gradually rounded slope and 

 the head is shorter and more obliquely narrowed behind the 

 eyes. Characteristic, as compared with most of the species of 

 the flams group, is the fact that the coxa? and trochanters are 

 not black. 



Salius iobates, sp. nov. 



Claws with one tooth. Black, the abdomen with a bluish 

 tinge ; the antennae rufous yellow, the scape and the apical four 

 joints black ; the basal half of the wings fuscous-violaceous ; 

 the apical yellowish-hyaline ; the hinder wings entirely smoky 

 violaceous. V • 



Long : 24 mm. 



Hab. Kuching, Sarawak. 



Head black ; the part between and below the antennae 

 testaceous ; the clypeus with a brownish tinge ; its apex rufo- 

 testaceous. Front and vertex alutaceous ; the front distinctlv
