282 ORTHOPTERA OF NOVA SCOTIA. PIERS. 



its apex extending towards the base of the wing; beyond this a triangular, 

 semi-clear area, veined with blackish, with its costal margin dusky; and the 

 apex of the wing dusky. Hind femora pale smoke-gray or grayish white, 

 with about four bands of black, the basal ones more or less merging into each 

 other and the terminal one embracing the knee; the gray of femora most 

 conspicuous as a subterminal annulation. Hind tibise pale smoke-gray or 

 grayish white, banded at each extremity and submediaUy with black. Feet 

 tawny-oUve. Eyes black or black spotted with gray. Antennae blackish. 



Measurements. — Male (Nova Scotia): body, 24-25 mm.; antennae' 

 10.5 mm.; pronotum, 5-5.2 mm.; wing-covers, 25-26 mm.; hind femora, 12- 

 12.5 mm.; hind tibise, 10-10.5 mm. Female (Nova Scotia); body, 25.5-28 

 mm.; antennae, 9.5-10 mm.; pronotum, 5-5.8 mm.; wing-covers, 24.5-27 mm.; 

 hind femora, 11.5-13.5 mm.; hind tibiae, 10-11 mm. 



Range. — Canada from Atlantic to Pacific and northern United States 

 from Atlantic to Rocky Mountains: from Nfld. (Port aux Basques), Nova 

 Scotia, New Bruns. (Moncton), Montreal, Quebec, Out., Man., Athab., 

 and Br. Columbia (Vancouver), south to New Jers., 111., Missouri, Nebr., 

 Dak., Mont., and Colo. Though common on bare ledges in northern New Eng. 

 it rarely occm^s as far south as Mass. (Scudder, Orth. N. E., 1900). It is 

 common in the mountains of New York, and in the southern part of its range 

 is found at high elevations. It thus appears to be distributed over the Cana- 

 dian, Transition, and elevated portions of the northern Upper Austxal Zones 

 or perhaps outliers of the Transition in that zone. In its southern limits, 

 and no doubt generally, it is a more northerly species than D. Carolina. 



Occurrence in Nova Scotia. — Many years ago this species 

 was collected in Nova Scotia, probably by Lieut. Redman 

 about 1821, but Francis Walker of the British Museum in 

 1870 and 1872 erroneously determined the two specimens 

 then taken as (Edipoda rugosa ( = Hippiscus rugosus Scudder), 

 and (Edipoda sulphurea { = Arphia sulphurea Fabricius), 

 species which might possibly occur here but which have not 

 yet been otherwise reported. He makes no mention of 

 (Edipoda verruculnta ( = Circotettix verruculatus) as occurring 

 outside of Massachusetts, U. S. A. (See Walker, Cat. Derm. 

 Salt. Brit. Mus., iv, 729-731, 1870; and Can. Ent., iv, 31, 

 1872). In 1916, Mr. Cummings of the British Museum, 

 examined for me Walker's single Nova Scotian specimen of 

 "(E. rugosa" which fortunately is still in that institution's 

 collection, and it proves to be C. verruculatus; and under 

 C. verruculatus in the same collection, is another specimen, 

 of Walker's determination, from Nova Scotia, which had 

 been named by him "(E. sulphurea." These two names of 

 Walker, as far as they apply to Nova Scotian specimens,
