NOTES ON IRISH HYMENOPTERA ACULEATA, 

 WITH SPECIAL REFERENCE TO THE DUBLIN 

 DISTRICT. 



BY A. AV. STELFOX, M.R.I.A. 



Wiiii.E re-arranging the collection of Aculeates (Ants, Wasps 

 and Bees) in the National Museum, I found, amongst material 

 collected by Mr. J. N. Halbert in years past, examples of 

 several species which had not been recorded from Ireland. 

 Moreover during the last two summers I have made a few 

 more additions to the list. At the same time I take this 

 opportunity^ of recording the capture of some of the rarer 

 Irish species — many of which have not previously been 

 reported from the Dublin district — and of correcting a 

 few errors which, from time to time, have crept into the 

 Irish list. My own records are the nnore valuable for the 

 reason that all my specimens have passed through the 

 hands of Dr. R. C. L. Perkins, F.R.S., of Newton Abbot, 

 Devonshire, to whom I am very deeply indebted and desire 

 to tender my thanks. Since the Irish List — published by 

 the late P. E. Freke in this Journal for 1895 — appeared very 

 little serious work at the Aculeates has been attempted in the 

 South or East of Ireland except that done in Kerry and 

 Cork by Col. Yerbury' and some sporadic work in Dublin 

 and Kerrv by the late H. Gore Cuthbert.^ In connexion 

 with the Clare Island Survey a report on this group was 

 written by Mr. Claude Morley,^ based upon his own work 

 and that of the Rev. W. F. Johnson, J. N. Halbert, and 

 P. F. Grimshaw. A portion of the material collected is 

 now in the National Museum, and I regret to have to 

 record the fact that all of it was not correctly determined, 

 which tends to make me distrust several of the records 

 for species of which I have not seen specimens. The chief
