ORTHOPTERA OF NOVA SCOTIA. — PIERS. 



known regarding the relative abundance of some species 

 to make the grouping at all definitive. It is therefore merely 

 a suggestive grouping, prepared specially to court subsequent 

 revision which will bring us nearer the facts. 



Canadian Zone. 

 (Atlantic seaboard and eastern Nova Scotia). 



Chorthippus curtipenms] 



Dissosteira Carolina^ 



Circotettix verruculatus^ 



[Podisma glacialis. Hypo- 

 thetical.] 



Melanoplus atlanis-\ 



[Melanoplusfasciatus. Hypo

Melanoplus femur-ruhrumf 



Melanoplus hivittatus (phase 



femoratus) f 

 Scudderia pistillata'\ 

 Conocephalus fasciatus fascia- 



tusf 

 Nemohius fasciatus (variant 



vitiatus) t 

 Gryllus pennsylvanicus (variant 

 neglectus)'\ 



All these species also occur commonly in the Alleghanian 

 (western) section of the province, except of course the two 

 species which are merely hypothetically included in our 

 fauna. Podisma glacialis, if actually found here in the 

 future, will most likely occur in the Canadian Zone; and 

 Melanoplus fasciatus, another hypothetical inclusion, should 

 certainly be associated with the same zone. 



Alleghanian Division of the Transition Zone. 

 (Western Nova Scotia).

Acrydium granulatum\ Melanoplus extremus

 from Halifax; a very doubt- 

 ful record). *t
