THE CANADIAN ENTOMOLOGIST. 59 



lish Literature, History, etc., 96 pages ; 3rd, Mathematical, Physical and 

 Chemical Sciences, 98 pages ; 4th, Geological and Biological Sciences, 

 286 pages. The matter is well printed and on excellent paper, and the 

 whole work — notwithstanding that the lists of errata are rather longer 

 than they should be — is a credit to the country and an evidence of solid 

 progress in scientific research in Canada. 



Ottawa Field JVaturalists' Club, Transactions, No. 4, 1882-1883 ; 8vo.^ 

 pp. 8g, with one plate. 



This number, although somewhat late in being issued, is highly credit- 

 able to the Club, and shows that its members are still actively engaged in 

 working up the natural history of their locality. Following the Report 

 of the Council is the excellent and instructive address of the President, 

 Mr. James Fletcher, who is also Vice-President of the Ent. Soc. of Ontario. 

 Next in order are valuable papers on the Laurentian System, the 

 Fishes of the Ottawa District, the Ducks of the locality, etc. There are 

 also reports from the general branches of Geology and Mineralogy, 

 Paleontology, Botany, Conchology, Ornithology, and Entomology, the 

 last occupying six pages with the record of its excellent work. We 

 heartily congratulate our fellow laborers in natural science belonging to 

 this Club for the excellent example they have set their sister cities in 

 Ontario by their thoroughness and enthusiasm. 



The Butter/lies of Maitie ; by Prof. C. H. Fernald. 8vo., pp. 104, 

 illustrated with 28 figures. 



Our thanks are due Prof. Fernald for a copy of this work, designed 

 more especially for the use of students in the Maine State College, but 

 one which will be found very useful to all who take an interest in our 

 northern butterflies. In the introduction, which occupies 18 pages, brief 

 reference is made to the classification, transformations, external and 

 internal anatomy of insects, followed by an accentuated list of the names 

 of butterflies and an artificial key designed to aid in determining the 59 

 species which are recorded as found in Maine. The descriptions are 

 written in a plain and practical style, as free from technicalities as the 

 subject will admit of.
