ADDITIONS TO THE LIST OF HYMEN OPTERA-ACULE ATA 

 OCCURRING IN THE ISLAND OF GUERNSEY. 



BY W. A. LUFF, F.E.S. 



In this Magazine for June and July, 1902, and October, 1903, 

 Mr, Edward Saunders published a complete list of the Hiimenoptera- 

 AcuJeata ihen known to occur in the Islands of Jersey, Guernsey and 

 Alderney. During the present year Mr. E. L>. Marquand has devoted 

 a great deal of time and energy to collecting the Guernsey species. 

 The specimens captured have been submitted to Mr. E. Saunders for 

 examination and naming, the result being that 26 species are additions 

 to the list. The most interesting of these are Diodontus friesei. Kohl, 

 a non-British species, which had, however, been previously taken in 

 Jersey by Mr. Saunders, a species of Halictus of the suhaurotus group, 

 but worn and difficult to determine for certain, and Coelioxys afra, 

 Lep., which Mr. Saunders informs me is quite a southern species, 

 common in Algeria, Spain, &c. In Guernsey they were flying in 

 company with Megacliile arrjentata, Eab.
