IIYMENOPTERA ACULEATA OF SUFFOLK. 

 13Y THE llEV. J. II. HOCKING, M.A.., F.E.S. 



. xlfter forty years of jn'etty continuous work in India and at 

 home at Lcpidopfera, I have, during 1899 and 1900 been devoting my 

 leisure time to collecting the Ilymenoptera and Dlptera of Suffolk. 



During this time I have taken of Hi/nienoptcra AcuJenta 33 species 

 of Fossores, 10 of Diploptera, and 96 of Aiithophila ; or 139 of the 

 2S2 species in the Suffolk list. 



I am indebted for most kind help in naming the species to the 

 llev. E. N. Bloomfield of Guestling, Mr. Harwood of Colchester, and 

 to Mr. E. Saunders, who has finally identified all doubtful specimens. 



Sphecodes riibicuiidiis, Halictus zoindits, II. breviceps, Nomada 

 sexfasciata, and Andrena Hattorjiana are additions to the last Suffolk 

 list as published iii 1899.
