Description. — Disk of pronotum with front margin nearly truncate and 

 hind margin obtuse-angled; median carina high, cut in front of middle by 

 deep narrow notch, its front lobe almost straight and the hind one arched; 

 lateral carinoe rounded and extending forward oidy to principal aulcus. Wings 

 and wing-covers extending about one-third their length beyond abdomen. 



Colour. — Xova Scotian specimens. General colour varies somewhat, but 

 is generally clove-brown (brown-black) and dark hair-brown; under parts 

 lighter and more brown in tint, vath a tendency towards mumrny-brown. 

 Wing-covers broccoli-brown, much clouded and obscurely spotted with clove- 

 brown. Hind wings dark clove-brou-n or black, with a primrose-yellow or pale 

 sulphur-yellow outer border the width of which is about one-sixth of length of 

 wing, the apex smoky with several fuscous spots. Hind femora with inner 

 face whitish and crossed by three blackish bands, the first nearly covering 

 the basal half; hind tibise dirty yellowish. 



Measurements. — Male: body, 26-30 mm.; antennse, 10-11 mm.; pronotum, 

 7 mm.; wing-covers, 29-34 mm.; hind femora, 1.3-16 mm. Female: body, 

 34-40 mm.; antenme, 12-13 mm.; pronotum, 10 mm.; wing-covers, 37-42 mm.; 

 hind femora, 16-20 mm. 



Range. — This common species is very widely distributed, occurring 

 in Canada and the United States from Atlantic to Pacific: from Nova Scotia, 

 New Bruns. (Point du Chene), Montreal, Ont., Man., and Br. Columbia, 

 south to Fla., iNIiss., Central Amer. (?), New Mexico, and Calif. It thus 

 occurs in the Canadian, Tran.'jition, Upper and Lower Austral zones. In 

 New Eng. it is ever^'where abundant. 



Occurrence in Nova Scotia. — This species was first reported 

 from Nova Scotia by Francis Walker of the British Museum 

 in 1870, doubtless from specimens collected by Lieut. Redman 

 about 1821. It is fairlj^ common in all suitable localities in 

 Nova Scotia, being found with Circotettix verruculatus on 

 hot, dry, stony places, bare ground, dusty roadsides, and 

 particularly on the ballast of railways; and it more or less 

 resembles in colour the predominant tint of its habitat. It 

 is much less abundant than C. verruculatus which it very 

 closely resembles when on the ground, and with which 

 it shares its habitat. Strange to say. Bayard Long did not 

 happen to meet with it in Prince Edward Island in 1912, 

 although it must sureh* occur there; but he collected it at 

 Point du Chene, N. B., on 11 Aug., 1912 (E. M. Walker, 

 Can. Ent.. 47, p. 841, 1915;.
