242 ORTHOPTERA OF NOVA SCOTIA. — PIERS. 



lands of the Cobequid and North Mountains might 

 also repay investigation. More information is desired 

 regarding the time of hatching of various species in N ova 

 Scotia, as we have very little data "on that subject. I have 

 already referred to the need of a detailed delineation of the 

 boundaries of our life zones, and this is a matter which 

 interests every biologist. 



Acknowledgments. — Finally, I wish to acknowledge par- 

 ticular indebtedness to Mr. Charles Benjamin Gooderham, 

 B. S. A., late assistant entomologist, Agricultural College, 

 Truro, N. S., who since 1913 has made a study of our Orthop- 

 tera, for very many notes with which he has furnished me, 

 they more particularly relating to the western section of 

 the province, in which I have had fewer opportunities for 

 collecting.* To the writings of the late Dr. S. H. Scudder, 

 Prof. W. S. Blatchley, B. H. Walden, and many others 

 whose names will be mentioned from time to time in the 

 text, I am also under obligations. Dr. Scudder, in the 

 generous manner which characterized that delightful personage, 

 verified mj'- determinations of nearly all my eailier species 

 of 1895-6. His death on 17th May, 1911, removed the most 

 prominent figure in North American orthopteiology. Mr. 

 James A. G. Rehn of the Academy of Natural Sciences, 

 Philadelphia, and Dr. E. M. Walker of the University of 

 Toronto, have kindly answered various enquiries. 



♦Mr. Gooderham has very recently been transferrerl to the Central Experimental" Farm, 

 Ottawa, as aaaistant to the Dominion Apiarist, Bee Division.
