 compressed; antennae short; pronotuin with disk flat and smooth, nmch wider 

 behind, truncate in front, obtusely angled behind, its median carina low, of 

 equal height througiiout, faintly cut once by principal sulcus in front of middle; 

 sides of pronotuin deeper than long; wing-covers narrow, reaching beyond 

 abdomen. 



Colour. — General colour light brown; antennic pale at base, darker 

 toward apex; a dark triangular sjjot behind eye, and a vi-rtical dark spot f)n 

 the front half of the lateral k)be of pronotum; wing-covers smoky-brown, with

Range. — Southern Canada and northern and western United State f 

 from Atlantic to Pacific: from P. E. Isld., Nova Scotia, Montreal, Manitoba, 

 and Br. Columbia, south to Conn., northern Ind., Nebr., Colo., New Mexico, 

 Ariz., and Calif. It thus occurs in the southern part of the Canadian, the 

 Transition, and probably- the northern i)ortion of the Upper Austral Zones. 

 In northern New England it is common, often excessively so, especially on 

 dry hillsides. ' 



Occurrence in Nova Scotia. — This somewhat sober- 

 coloured locust, which lacks the brightlj^-coloured inner 

 wings of most of the CEdipodincB, is apparently rather uncom- 

 mon about Halifax, but is reported to vary from common 

 to very common in the western parts of the province where 

 it is one of the most injurious species.* It was first reporte I 

 from Xova Scotia in 1896. I captured a female, in company 

 with Circotettix verruculatus (which it somewhat re.?embles 

 when on the ground) in a stony place near Blockhouse (Stan- 

 ford's) Pond, Fairview, Halifax, on 5 Sept. 1895; and a 

 second female in a damp, grassy spot on the roadside close 

 to Cow Bay Bridge, Cow Bay, about seven miles southeast 

 of Dartmouth, Hx. Co., on 2 Oct. of the same year. The 

 determination of the species was verified ])y Dr. S. H. Scudder 

 who examine:! the latter specimen. Among some Orthoptera 

 sent to me by Miss Lucy C. Eaton, was a third female taken 

 by he; at Truro, Col., Co. 23 July 1991 (Prov. Museum, Ace. 



*Mr. Gaoderham's statement (Acrididse of N. S., 1917, p. 26), that it is "very common 

 all over the province, occurrin-? wherever M. femur-rubrum or M. atlans is found," does not 

 at all ap;>ly ta the canditions about Halifax, where it is at most only uncommon.
