ORTIIOPTERA OF NOVA SCOTIA. — PIERS. 221 



of various species in Nova Scotia, all based on my 

 paper of the former date, but there is no need to 

 refer to them here, as they are merely secondary 

 references, not original records. 



1917. — Gooderham, C[harles] B[enjamin]. The Acrididae of 

 Nova Scotia. Proc. of Entomological Society of 

 Nova Scotia for 1916, no. 2, [Truro], Jan., 1917, 

 pp. 21-30, and 1 plate. 



Lists 13 nominal species, with keys and descrip- 

 tions. The material for this paper was collected 

 during 1913 and 1914 and it was founded on the 

 author's thesis for his degree of B. S. A. at Macdonald 

 College, Ste. Anne de Bellevue. 



Reference works. — Among the available literature which 

 will probably be most useful to a student of the Orthoptera 

 of this section of Canada, may be mentioned the following 

 papers of recent dates, from which it will be seen that there 

 is no general manual on the subject, and one is therefore 

 forced to rely upon various scattered sources of information. 

 1894-98. — Morse, Albert P. Notes on the Acrididae of New 



England. Psyche, vol. 7 (Cambridge, 1894-97), vol. 



8 (1897-98).
