THE COLEOPTERA OF SUFFOLK.
THE COLEOPTERA OF SUFFOLK. Second Supplement.
BY ERNEST A. ELLIOTT, F.Z.S., F.E.S., ETC. SINCE the
year 1915, when Mr. Claude Morley issued the First Supplement, comprising 219 species, to his 1899 " Coleoptera of Suffolk " which contained 1763 kinds of local Beetles, a constant record has been maintained of any additions that have been discovered. The total now attained is considered sufficiently large to Warrant the publication of a second Supplement ary list, including the following seventy-five Beetles, with the localities of their occurrence and the names of their captors. Every Coleopteristfindsthat it is very difficult to extend far beyond the two-thousand mark, for the rest are all either regarded as being of very rare occurrence in Britain as a whole— frequently, doubtless, solely on account of our own ignorance respecting their habits and habitats—or so obscure in their individuality and discrimination as to render their identification most critical. In thefirstrespect the present inclusion of Aetophorus imperialis, Anchomenus atratus, the Hyperaspis Criocephalus, demonstrates that the tail of our conspicuous insects is not yet exhausted ; but to the second, whereto the very great majority of these additions pertain, we must turn for future augmentation of the List. Here the difficult genera Homalota, Cryptophagus, etc., with the entire family of mmute Trichopterygidce, would yield numerous novelties to anyone sufficiently occulatissimus to work them out. However, our present list compares favourably enough with those of other English counties: to the best of my knowledge Norfolk possesses 1803 species ; Essex 1649 ; Kent 2350 ; Surrey 2346 ; Lancashire and Cheshire, combined, 1486 ; and the whole of Ireland only 1630 different kinds. Prof. Sir Hudson Beare's fortheoming " Catalogue of British Coleoptera " exhibits 3566 species with thirteen others in the Addendum, of which one is a known error and two more, unnumbered, figure in the text: giving us a total 3580 species in all our Islands. Out of these, the present Supplement brings up the known Suffolk total to 2056 species, so no cause is shown for us to be idle yetawhile ! GEODEHAGA.
