THE CANADIAN ENTOMOLOGIST. 159 



Dkar Sir,- 



A few days ago I went to a swamp where PJucton feeds in early spring, 



and discovered several of the webs of that species spun over the stems 



of Chdone glabra and whatever other plants were contiguous. Within 



the webs were larvae about 3<( inch long, and as during the last few days, 



since 1 have had a number of them in the house, there is no appearance 



•of feeding by the larvae, I presume they are quiet for the season and 



till next March, Seeing a good many Phyciodcs mania flying in the 



-swamp, it occurred to me to try a female with a stem of Cheloiic glabra, 



and I did so with satisfactory results, as three days after I enclosed her 



in a bag, she laid about 75 eggs on the under side of one of the leaves- 



I hope I have at last found the food plant of this species, after having 



tried a score of plants to no purpose.

' EDITORIAL SUMMARY. 



Palaeontology of Ontario. — We are much pleased to observe that 

 the Legislature of this Province is extending its liberality in the cause of 

 Science to other departments, besides those somewhat utilitarian branches 

 of Entomology and Horticulture, as is eminently manifest from the 

 excellent Report before us on the Palaeontology of Ontario. It has been 

 prepared by Prof. H. Alleyne Nicholson, of the University of Toronto, 

 and contains descriptions and figures of the organic remains of the 

 Devonian Formation of Western Canada. No less than one hundred 

 and sixty species of fossils are described, and illustrated by means of 

 nearly sixty wood-cuts in the text, and eight splendid lithographic plates. 

 It is noteworthy, also, that all the figures are original, except two of the 

 wood cuts. We trust that the Legislature will long continue its assistance 

 to this excellent work, and that Prof. Nicholson may be enabled to carry 

 out a complete investigation of the Palaeontology of all the fossiliferous 

 geological formations in this country. 



Among the " old country '■ publications that we have lately received, 

 Ave may mention the 15th number of the Scoftis/i A'a/ura/ist (Dr. F. B. 

 AVhite, Perth.) We gather from its pages that a goodly number of Field 

 Clubs are being organized in Scotland, and that much satisfactory work
