ORTIIOPTERA OF NOVA SCOTIA. — PIERS. 267 



carina seems to pass diagonally across a black line which therefore adjoins 

 it first on one side and then on the other. \\'ing-cover8 brownish cream-bufiF. 

 Hind femora pale vandyke-brown on disk, upper edge chromium-green, 

 lower edge yellowish, knee black; hind tibiae pale vandyke-brown, narrowly 

 blackish at base. 



Greenish olive-gray phase. — Upper parts of head arid pronotum cream- 

 colour; upper i)art of abdomen cream-buff with a black spot on anterior 

 part of each segment. Face whitish; sides of head and of pronotum tea-green 

 (greenish olive-gray), which gives this variant its predominant colour; sides 

 of abdomen black, more or less marked with yellowish. Under parts canary- 

 yellow. Sometimes two black lines on top of head; a black bar from eye to 

 pronotum. The white latei'al carina; of pronotum, and adjoining velvety-black 

 lines, are disposed in preciselj^ the same manner as those of the green phase. 

 Wing-covers cream-buff on dorsal area, wood-brown on lower area; veined 

 with fuscous. Hind femora brownish olive-green on disk, canary-yellow on 

 basal half of lower edge, knees black; hind tibise wood-brown, narrowly banded 

 with black at extreme base; spines black. 



Brownish phase. — This resembles the greenish-olive-gray and green 

 phases, except that the sides of head and pronotum are brownish of yellowish- 

 brown. 



Of 9 specimens (5 adults and 4 nymphs) taken on the beforementioned 

 date, 3 were green, 2 were olive-gray, and 4 were brownish. Of the males, 

 2 were green, 2 were olive-gray, and 1 was brownish ; and of the females, 1 was 

 green, and 3 were bro^vmish. The two black lines on top of head were wanting 

 on 2 (females) of the bro'miish lot, and also on 1 (male) of the green lot. In 

 the adult males the wing-covers reach to the end of the abdomen, and in 

 the adult females they cover about two-thirds of it. 



Measurements. — Nova Scotian specimens. Male: body, about 15 mm.; 

 antennte, 8.7 mm.; pronotum, 3 mm.; wing-covers, about 9.5 mm (2.2 mm. 

 short of end of hind femora, but varies); hind femora, 10 mm.; hind tibiae 

 9.5 mm. Female: body, about 18.5 mm. (but varies); antennae, 6.7 mm.; 

 pronotum, 3.5 mm.; wing-covers, about 9 mm. (5.2 mm. short of end of 

 hind femora, but varies); hind femora, 12.2 mm.; hind tibiae, 11 mm. 

 Writers have described a short- and a long-winged form (the latter 

 sometimes called var. longipennis) , but they intergrade. In the former 

 the wing-covers are usually about 2.5 mm. (males) or 4 mm. (females) 

 short of end of hind femora; while in the latter they reach the end of 

 femora or slightly surpass them. In Nova Scotian males they mostly 

 reach the end of the abdomen, and in females they usuallj' cover about two- 

 thirds of it; that is in the former their apex is about 2.2 mm. short of the 

 apex of the hind femora, and in the latter about 3 mm. short of the end of 

 the abdomen and about 5.2 mm. short of the femoral apex. 



Range. — Northern United States and Canada east of Sierra Nevadas 

 and mostly north of lat. 40°: from southern Nfld., P. E. Island, Man., Sask., 

 and Alb., south to N. Caro., 111., Neb., Colo., and Nev. It is thus mostly 

 confined to the Canadian and Transition Zones and probably the northern 

 portion of the Upper Austral. One of the commonest species in New Eng- 

 ] and and other parts of its range. 



Occurrence in Nova Scotia. — This very common species 

 was first recorded from Nova Scotia by F. Walker in 1870. 

 In Aug., 1912, B. Long collected 31 specimens in the neigh- 

 boring province of Prince Edward Island, and also took it 

 at Moncton, N. B. (E. M. Walker, Can. Ent., 47, 1915).
