122 HYMEISOPTERA OF SARAWAK. 



VESPIDiE. 

 Vespa annulata, Smith. 



This form has been taken by Mr. Hewitt at Santabong 

 Matang (December) and Kuching (January). In the recently 

 published Monograph of the genus Vespa by the Viscount du 

 Buysson (Ann. Soc. Ent. de France, LXX, III, (1904) p. 542), 

 annulata is considered to be a variety of bellicosa Smith. I 

 am not sure but that when the 6 has been discovered, it will 

 be proved to be a good species. 



If not a distinct species it certainly forms a well-marked 

 race of bellicosa. 



Vespa bellicosa (type) has been taken by Mr. Hewitt at 

 Pulo Burong.
