I. Majorca (1901). 



The Majorcan Aculeates named and described by Mr. 

 Saunders in this memoir were collected by Mr. W. 

 Holland, of the Hope Department, Oxford, Mr. A. H. 

 Hamm, of the same Department, and myself. The 

 entire collection was made from June 26 to July 12, 

 1901, in the neighbourhood of Palma, Seller and Pollensa, 

 or in travelling between these places. 



On returning home with many thousands of specimens 

 belonging to nearly all groups, including those obtained in 

 a week's hard work on the mainland, the expenditure of 

 an immense amount of careful mechanical labour was 

 necessary before the work of determination could begin. 

 Interrupted by calls which could not be postponed, about 

 eighteen months elapsed before I was in a position to 

 submit the Aculeates to my kind friend, Mr. Edward 

 Saunders, F.R.S. , who has rendered such memorable help 

 to the Hope Department on many occasions. 



The Majorcan Aculeates numbered rather over 3680, 

 and of these about 2500 were in the first instance ex- 

 amined by Mr. Saunders. The remaining specimens, 

 which had been looked upon as duplicates of the com- 

 monest species, were subsequently studied by him, and a 

 few species of interest recovered from among them. 



It will be seen in his memoir that Mr. Saunders recog- 

 nises five new species in this material : — Fompihcs poultoni, 

 Mimesa palliditarsis, Halictns dtthitabilis, If. hollandi, and 

 H. hammi. 



It is unnecessary again to describe the features of this 

 beautiful island with its triple division into (1) level 

 highly-cultivated plains, (2) mountains chiefly developed 

 along the N.-W. coast, and (3) low marshy land on the 

 N.-E. bordering parts of the bays of Alcudia and Pollensa.
