26 HYMENOPTERA FROM BORNEO. 



Icaria intermedia, Cam. 



This species (described from Java, Tijdsch. voor Ent. 

 XL VIII) has been taken at Transan, Borneo in August. The 

 band on the apex of the 2nd abdominal segment is slightly 

 narrowed at the base in the middle. 



Icaria maculifrons, Cam. 



A very dark, blackish example of this species has been 

 taken at Merdang in December. 



Icaria artifex, Sauss. 



Two very dissimilar specimens, as regards the size of 

 yellow marks and their shape — one from Kuching in March, 

 the other from Sadong in August. The usual yellow line on 

 the sides of the petiole may be absent or greatly reduced ; the 

 shape of the marks on the 2nd abdominal segment varies, and 

 the line on the clypeus may be black or red. 



Jour. Straits Branch.
