THE CANADIAN ENTOMOLOGIST 391 



has been able to establish the identity of the species recorded by 

 Francis Walker (Cat. Derm. Salt. Brit. Mus., 1869-71). This 

 part also contains an account of the life zones of Nova Scotia with 

 the distribution of the Orthoptera within these, useful information 

 on climatic conditions of the Province in relation to the time of 

 hatching and other phenomena of seasonal distribution, and some 

 interesting comparisons between the faunas of Nova Scotia and 

 other regions in Eastern North America, more particularly New 

 England. 



Part II contains keys to the families, genera and species, with 

 descriptions of each form and full notes on distribution, both 

 general and local. There are also many interesting notes on habits 

 haunts, stridulation, etc. A very full account is given of the 

 variations in Nova Scotian specimens of the common field cricket, 

 Gryllus pennsylvanicus {G. assimilis). 



The following minor errors may be noted here: 



P. 256. Nomotettix cristatiis has been reported from Go 

 Home Bay, Georgian Bay, Ont., in addition to the Toronto record 

 (39th Ann. Rep. Ent. Soc. Ont., 1909, p. 113.) 



P. 297. The macropterous form of Melanoplus fasciatus, 

 stated to be known only from Michigan, has been reported also 

 from Lake Simcoe (Can. Ent., XXXI, p. 32), Fort William and 

 the Temagami District Ont. (1. c, XLI, pp. 142, 207). 



P. 325. The genus Ceuthophilus is now referred to the sub- 

 family Rhaphidophorinse, not the Stenopelmatinse. 



P. 336. Concerning Nemobius carolinus it is stated that the 

 present author "does not report it from Ontario (1904), although 

 his common iV. angusticollis seems to be a somewhat related form." 

 The latter name has been placed in the synonymy of N. carolinus 

 (Walker, Can. Ent., XLI, p. 211). 



The paper is illustrated by four plates and several text figures, 

 characters of all the species being shown.
