302 ORTHOPTERA OF NOVA SCOTIA. PIERS. 



scandens) ; hind femora, 10 mm. Female : body, 19-28 mm. ; pronotum, 5 mm. ; 

 wing-covers, about 11 mm. {M. e. Junius) to about 17 mm. (M. e. scandens) y 

 hind femora, about 11mm. (Short-winged specimens of extremely large size, 

 males with bodies up to 24 mm., and females up to 28 mm., with correspond- 

 ing increase in size of wing-oovers, hind femora, etc., have been lately recorded 

 by Dr. E. M. Walker from the Magdalen Islands. Northern specimens of 

 this species are distinctly larger than more southern ones.) 



Range. — M. extremus in either its short or long-winged form or both> 

 ranges over the larger part of Canada and northernmost United States: 

 from P. E. Island (both short- and long-winged forms), Nova Scotia (short- 

 winged form). New Bruns. (short-winged form), Magdalen Islds. (short- 

 winged form,) Bic (Quebec, both forms). Alb , Gt. Bear Lake (about lat. 65°), 

 and Alaska (lat. 66° 30'), south to Mass., Ind., 111., Iowa, Neb., and Wyom. 

 It is confined more or less to the Hudsonian, Canadian, and Transition Zones, 

 ranging further north in the west than in the east. In the northern half 

 of New England it is common, and reaches the summits of the highest 

 mountains. 



Occurrence in Nova Scotia. — Only the short-winged 

 form (sometimes called M. extremus Junius Dodge) has 

 so far been detected in Nova Scotia, although the long-winged 

 one should also occur and no doubt will yet be met with. 

 The species has not before been reported from this province, 

 and the credit of adding it to our list belongs to C. B. Gooder- 

 ham who collected three short-winged females at Truro, 

 Col. Co., on 28 July, 1913, and 5 July, 1914, their determina- 

 tion being verified by Dr. E. M. Walker of Toronto. He also 

 reports a female taken by G. F. Collingwood in Kings County, 

 N. S., but when received it had no precise data as to exact 

 place where captured or date. He likewise has a short- 

 winged female collected at Hillsboro, in the neighbouring 

 province of New Brunswick, on 8 Aug., 1913, by Miss V. L. 

 Tarris, from which province it has also not previously been 

 reported. He considers it rare al)out Truro, and I have 

 never noted it about Halifax. From its known range, this 

 boreal species was to have been expected to occur here, as 

 B. Long had taken three specimens in Prince Edward Island 

 in the summer of 1912, namely a short- Ou'w'ws) and a long- 

 winged (scandens) male at Souris, and a short-winged female 

 at Southport (E. M. Walker, Can. Ent., 47, p. 342, 1915). 

 The long-winged form is probably more frequently met with 

 at high elevations as well as high latitudes.
