We thus see how sparse our orthopteran fauna is in 

 species, and this, as before stated, is just as might be expected 

 considering our geographical position and climatic conditions. 

 E. M. Walker's preliminary list of Prince Edward Island 

 Orthoptera, consisting of 11 nominal species, is doubtless 

 fairly well under the actual number which will yet be found 

 there, but it is very unlikely that that list will ever go over 

 20 species. Regarding New Brunswick we have almost no data 

 at present; but its species should slightly exceed in number 

 those of Nova Scotia, owing to the much more ready passage 

 inward of forms from the adjoining state of Maine. From 

 Newfoundland only six species have so far been reported 

 (Hebard, Ent. News, xxvi, p. 306, 1915).* 



It may be here noted that the two species admitted to 

 my present list on hypothetical grounds, namely Podisma 

 ^lacialis and Melanoplus fnsciatus, have been included 

 because they have been reported both from Prince Edward 

 Island on the north and from Maine to the south, and there- 

 fore it is hardly possible that they will not yet be found here 

 in certain favourable localities. No species of more southern 

 range only, have been thus admitted; and all references 



♦The species reported by Hebard from Newfoundland (G. P. EnRlehardt collector, Aug.' 

 1912) are, Chorlhippun rurtipeitni!' (Har.), Meroffe'lius gracilix (Scud.), Cirroteltix verruculalua 

 (Kirby), Melanoplus fascialus (Walk.), Melaiwplus /emoratun (Burm.), and Ceuthophilui 

 terrealris. Scud.
