2. On the Hymenoptera collected during the '^ Skeat 

 Expedition" to the Malay Peninsula, 1899-1900. By 

 P. Cameron \ 



[Eeceived April 15, 1901.] 



The Hymenoptera of the Malay Peninsula are far from well 

 known. In addition to the species of Aeuleata from Tenasserim 

 mentioned in Bingham's ' Fauna of British India, Hymenoptera,' 

 our chief, almost our sole, authoi-ity on the subject is the late 

 F. Smith, who in 1858 described (Journ.Linn. Soc. ii. pp. 42-130) 

 the species found by Dr. A. E. Wallace at Malacca and Singapore. 

 Including Ants (which are not dealt with in this paper) Mr. Smith 

 enumerated 1 36 species from the Peninsula. The collection on 

 which this paper is based was formed by Messrs. Annandale, Evans, 

 and Laidlaw, members of the Skeat Expedition, chiefly on the eastern 

 side of the Peninsula, which entomologically is the least known part. 

 Though small, the collection contains examples of several new and 

 interesting forms. 



In Bingham's ' Hymenoptera of British India,' out of a total 

 of 995 species of Aeuleata (other than Ants) no less than 376 are 

 recorded from Tenasserim, the extreme northern district of the 

 Malay Peninsula ; and there can be no doubt that if the Peninsula 

 were adequately explored it would prove to be extremely rich in 

 Hymenoptera. 



I have included a few species that were not found by the members 

 of the Skeat Expedition, and also some allied forms from neigh- 

 bouring regions. As a matter of convenience these are placed in 

 their pi-oper positions and are distinguished by square brackets.
