In another chapter on ‘“‘ The earliest winged Insects of America,” 
Prof. Scudder gives to the scientific public the result of his ‘ re- 
examination of the Devonian Insects of New Brunswick, in the 
light of criticisms and of new studies on other paleeozoic types,” 
pp. 275—282. ; 
Gerephemera is here referred to the order Protophasmida and 
Homothetus is taken from the order Odonata, whilst the relations 
of the Devonian forms to Carboniferous more akin than at first 
supposed are given. The criticisms made by Dr. Hagen on Prof. 
Seudder’s works and writings are here treated in the kindly spirit 
of searching for light and finding it. 
VOLUME II. 
Volume II contains notes on and descriptions of the Tertiary 
insects of North America, and it is of special interest to students of 
Canadian Geology and Paleontology, inasmuch as it throws much 
light upon the structure and affinities of fossil specimens from two 
principal horizons in the stratigraphical- sequence, viz.: (1) the 
Miocene rocks of British Columbia, and (2) the Interglacial beds 
of Searboro, in the Province of Ontario. 
In this volume no less than sixty-seven Canadian species of 
insects are described in full and figured. They belong to the orders 
Hemiptera, Coleoptera, Diptera and Hymenoptera, which are here 
appended in tabular form, so as to make them easy for reference. 
Notes on the localities where these fossil insects are found are 
here inserted from the large monographs, and will no doubt prove 
interesting. These writings of Prof. Scudder will shortly be sup- 
plemented by description and figures of fossil insects from British 
Columbia, and from the Leda clay of Green’s Creek, near Ottawa. 
“The discovery of the different localities for fossil insects in 
British Columbia by the Geological Survey of Canada, has been due 
entirely to the investigations of Dr. George M. Dawson. On the left 
bank of the Fraser River, at the town of Quesnel, he discovered a 
Series of clays, sands and gravels, their upturned edges covered by 
the valley deposits, in one of which series (a stratum of fire clay 
éight or nine inches thick) insects and plants were found, the beds 
being exposed on the river bank at a low stage of the water. Nearly 
twenty species of plants were met with, mostly of apetalous families, 
in the neighborhood of the Cupuliferze, such as the beech, walnut, 
oak, birch and poplar, and a considerable number of insects. Such 
of these as are included in the present report consist of twenty-five 
species, nearly all Hymenoptera and Diptera, and especially the 
latter, and, what is very unusual, only a single beetle. Sir William 
Dawson, who determined the plants, regarded them as to a gorat
