REVIEWS. 
Pyrenees, the Riesengebirge, and Caucasus, respectively, by Ghiliani, 
Dufour, Kiesenwetter, Kolenati, and others; but scarcely one of them has 
produced a picture more full of life, or rich in details, than Zetterstedt, the 
earliest of the list. The greatest number of the new Dipterous genera, 
and a large proportion of new species, were characterized in this volume ; 
but we propose to treat all such together in our examination of the Diptera 
Scandinavia. This great work, a monument both of untiring industry, 
erudition, and acute discrimination, is comprised in eleven 8vo volumes, 
which average above four hundred pages each ; and the publication, com¬ 
menced at the author’s own expense, and afterwards worthily sustained by 
the public purse, has extended over a period of ten years. After a short 
preface, and list of works cited, an hundred and three pages are given to 
the analysis and characteristic of the families and genera. A final index 
of one hundred and ninety-two pages, containing the synonyms, as well 
as the generic and trivial names of the text, affords every facility for re¬ 
ference that can be desired. The specialities, analysis, description, and 
history of the species, with supplementary characters of the genera (two 
hundred and eighty-five in number), fill nearly four thousand two hundred 
and fifty pages, giving for each of the 3,462 species described, after all 
deductions, a good deal more than a page on the average. Of this num¬ 
ber, 1,585 purport to have been first described in one or other of the books 
we have titled, making the proportion rather more than five new species to 
six previously included among the European Diptera of Meigen; and of 
these last, Fallen had recorded but 845, where Zetterstedt has 1,260 in 
the corresponding families; so largely has the older stock of Fallen and 
Fries been added to by the author’s own travels in Lapland, and by the 
communications of Dahlbom, Wahlberg, Anderson, and Skogmann, 
from the same source; of Liebke, in Norway; Sahlberg, Nylander, and 
Mannerheim, in Finland; Stasger, Schioedte, Drewsen, Boje, Jacobsen, 
and Westermann, in Denmark; besides a list of about twenty corre¬ 
spondents in the Swedish provinces, including the honoured names of 
Schonherr and Bohemann. When will our own islands furnish such help 
to any one who may undertake for them a task like that Zetterstedt has 
achieved for his country ? Particular attention has been paid to the geo¬ 
graphical distribution of the species, and various localities are assigned for 
most of them; so that the names of some of these correspondents recur as 
authorities almost in every page. These volumes of Zetterstedt’s are the 
more available to the British student, as they are wholly written in Latin 
.—fair, entomological Latin; a quality which, without pretending to clas¬ 
sical nicety, we are not disposed to undervalue, with the recollection fresh
