of the present year. In glancing over this list I have noticed one omission. 63, — 

 '"Analecta Hemipterologica,' Berliner entom. Zeitschr. 1866 (not 1867), p. 387 S- 

 393," is followed by a continuation in the same volume, p. 381 to 394, in which four 

 new genera and ten new species are described. This Dr. Signoret appears to have 

 missed in his labour of love in recording the works of his late friend, whose death is 

 the greatest loss that systematic entomology has sustained for many years. — W. L.

This work, of which only 100 copies are printed, is wholly in the Dutch lan- 

 guage, and consists of descriptions of all the species of Hemiptera-Heteroptera 

 hitherto known to inhabit Holland, arranged in systematic order and illustrated by 

 the author. The genera employed are for the most part of old date, none being 

 adopted since those of Fieber, and not many of them ; which fact will be welcomed 

 by entomologists of conservative and synthetical views, but in even a greater degree 

 be displeasing and very surprising to the school of analytical subdividers. The 

 names will often not be tenable, — some from being improperly applied, e. g., Cimex, 

 Linn., Hydrometra, Fab. ; some from having been previously used, e.g., Pachymerus, 

 Lep. ; some from the heterogeneous character of the species associated under them ; 

 and some for other reasons ; but the student will soon rectify such matters. With 

 regard to species, the descriptions are full and sufficient, but the record of the syno- 

 nymy is marred by citing (with some exceptions) only authors and their works, 

 giving the page, &c., where the species is described, but not the name under which 

 it is described, although either in generic or specific appellation it often differs from 

 that adopted by our author, which, recent emendations not being noticed, are fre- 

 quently incorrect. There are no new species. The plates are in excellent style, the 

 figures (comprising 239 species) being, with few exceptions, very characteristic ; 

 and the most of the slight deviations from strict accuracy are pointed out in the 

 text. The work will be of great value to Dutch entomologists, and should 

 incite them to greater efforts in collecting and studying Hemiptera, which 

 appear to have been hitherto as much neglected in Holland as in most other parts 

 of Europe. In Britain also the work should be appreciated, on account of the figures 

 of many of our native species, which are not otherwise to be easily met with ; and it 

 should also have a special interest for us as showing the general community so far of 

 the Hemipterous fauna of the two countries, notwithstanding the occurrence in 

 Holland of some species rarely or never foimd in Britain. The curious thing is that 

 a great many species indigenous to Britain are not found in Holland — the British 

 being about 450 in number, whilst those here denoted are only 280 ; rather an un- 

 expected result, considering the geographical position of Holland on the continent 

 (in the same latitude as our midland counties), and the narrow, insular separation 

 of Britain therefrom. This proportion may, however, be varied when Holland has 

 been better worked by Hemiptei-ists, unless it should prove that its Hemipterous 

 fauna is more limited than that of Britain by geological causes or surface conditions 

 of vegetation and cultivation.
