Manchester— J. R.H. Mr. J. T. Green, Birkenhead— 

 J.T.Gr. Their notes, and the full use of their collections, 

 most generously given, have very largely contributed to 

 the present list. The initials, as above, distinguish their 

 several records in the text. Where no initials occur, the 

 writer is himself responsible for the statement. 



In the year 1892 a " Preliminary List of the Hymenop- 

 tera Aculeata of Lancashire and Cheshire " was published 

 in the "British Naturalist," Vol. II., by the present 

 writer, and included all observations made to that date. 

 Since that time much less work has been done locally 

 among the Aculeata than could have been wished, owing to 

 our surviving observers being engaged in other researches, 

 or else living outside the limits of our two counties. 

 But some additions to our local Fauna have nevertheless 

 been made, and our knowledge of the range of many 

 species has been considerably extended, while one or two 

 former records have been proved to require correction. 

 Also, by the publication in 1896 of Mr. Edward Saunders' 

 " Hymenoptera-Aculeata of the British Islands," changes 

 have been made in nomenclature, &c, so that a new list 

 has become still further necessary for our local faunistic 

 literature. 



It will be seen from the above list of our local 

 workers that observations hitherto made have extended 

 over but a portion of our two counties, and that therefore 

 we are at present far short of sufficient data for a complete 

 Aculeate-Hymenopterous Fauna of the district. Still, 

 even as a basis for future work, it would appear to be 

 desirable to bring together the information obtained up 

 to date, and to this end the following paper is contributed 

 to the Transactions of the Liverpool Biological Society. 



The difficulty of naming ohscure species correctly is 

 often great. The writer and our local collectors, however,
