Aculeate Hi/menoptera in the Channel Islands. — Mr. J. R. le B. Tomlin 

 very kiudly sent me any Hymenoptera he was able to box on flowers during 

 a visit to Guernsey last June, and an examination of this material sbows a few 

 additions to the lists published in Eut. Mo. Mag. 1902, p. 140, and 1903, p. 245, 

 and by Luff in Ent. Mo. Mag. 1907, p. 39. The following is a complete list of 

 the species taken, an asterisk being placed against those which are apparently 

 new records for the Islands : —

I am indebted to my friends Dr. R. C. L. Perkins and Mr. Horace. 

 Donisthorpe for kindly examining most of these specimens, and, in com- 

 menting on the Ants, the latter writes that the occurrence of Iridomyrmex 

 fiumilis — the Argentine Ant — is of great importance, as it is a terrible pest and 

 gets established very quickly, — II. M. Iiallktt, 64 Weatbourue lid., Penarth :
