Title: The Hymenoptera Aculeata of the British Islands : a descriptive account of the families, genera, and species indigenous to Great Britain and Ireland, with notes as to habits, localities, habitats / by Edward Saunders.
Abstract: bution of the species outside the British Isles could be usefully added to the localities given, but there is so much doubt about the identity of many of the British and Continental species which bear the same names, and different countries have been so unequally worked by collectors, that to define areas at present would, if the author may adapt an expression from a critic of his former work on Hemiptera Heteroptera, throw more light on the distribution of Hymenopterists than on that of Hymenoptera.The species of Hymenoptera Aculeata now known to be indigenous to this country number 374.Of these 20 belong to the Heterogyna, or Ants; 127 to the Fossores, or Sand Wasps; 23 to the Diploptera, or true Wasps; and 204 to the Anthophila, or pollen-collecting Bees.There are, no doubt, others yet to be found, and the author trusts that all who have doubtful specimens will send them to him for examination, as he is always ready to be of use if possible, and it is amongst the doubtful ones that additions to our fauna are likely to be discovered.
