INTRODUCTION. 



The district from which Coleoptera were collected had as its centre Clare 

 Island ; it included Achill Island, and extended eastwards to Castlebar and 

 southwards to Killary Bay, excluding the Galway side ; it thus forms a 

 district of considerable size and variety of surface. Work at the Coleoptera 

 had been done in the district previously to the Survey of 1909-11 by 

 W. E. Sharpe, L. H. Bonaparte Wyse. J. N. Halbert, and Commander Walker, 1 

 and their records are incorporated in the present list. 



The work of the section of the Clare Island Survey devoted to the 

 Coleoptera was carried out by Rev. W. F. and Mrs. Johnson and Mr. J. N. 

 Halbert, with assistance from Messrs. C. Morley, R. Welch, and N. H. Foster 

 Mr. L. H. Bonaparte Wyse was collecting in the district on his own account, 

 and very kindly sent us a complete list of his captures. We are also indebted 

 to several other workers for specimens collected during the Survey. 



With regard to our work in the district, W. F. and Mrs. Johnson collected 

 at Curraun, Achill, and Mulranny in June, 1910 ; at Clare Island in September, 

 1910, and in June, 1911. Halbert worked at Clare Island, Achill, and 

 Westport in June, 1909 ; at Belclare and Louisburgh in July, 1910 ; and 

 at the Westport district in July, 1911. 



As a -result we are able to present a list of 521 species of Coleoptera. 

 This cannot be regarded as anything like a complete list of the beetles of the 

 district. Such a list could only be compiled by resident collectors working all 

 the year round for several years in succession. This will at once be under- 

 stood when we mention that the late Mr. Buckle's list 2 of the beetles of the 

 Foyle district, comprising parts of Donegal and Derry, which was the result 

 of three years' energetic and skilled collecting by one resident continuously in
