North Bay and Algonquin Park, Ont., Aug. 14 Sept. 12 

 (Walker). A northern race of glacialis, taken by Walker at the 

 localities mentioned and at Ft. William and the Temagami Dis- 

 trict, Ont. Known also from the Porcupine Mts., Keweenaw Bay 

 and Dickinson Co., Mich. Walker found them in both dry and 

 moist situations in open woods on bushes, chiefly the beaked hazel, 

 Conjlus rostra ta Ait. and the red raspberry, also on spruce. 

 Hebard took them at Keweenaw Bay by beating similar bushes 

 in August and early September, and states that the males are 

 active jumpers, quickly on the alert, but trusting to their very 

 protective coloration they would not move till almost touched by 

 the net. "The females," he says, "were a clear dull grass-green, 

 the exact shade of the cloth of a billiard table, the males deep 

 emerald green, appearing almost translucent, the back purplish- 

 brown with a median chain of cream-colored marks." 



Walker considers canadensis an intermediate form or race con- 

 necting P. glacialis with P. varicyata, but the great length of an- 

 tennae in the males of varicgata, taken in connection with the other 

 structural and color differences as given in key and description, 

 leads me to place that as a distinct species. 



152. PODISMA VAKIEGATA Scudder, 1897, 101. Variegated Wingless Locust. 

 Form and size of P. glacialis. General color chocolate-brown with an 

 olivaceous or greenish tinge. Male (of dried specimens) with face, a 

 broad pronotal median stripe narrowing and extending back along dorsal 

 surface of abdomen, lower halves of pronotal lateral lobes, two cross-bars 

 on dorsal face and a subapical annulus of hind femora, cream white or 

 dull clay-yellow. Antennae pale brown, dusky at tip. Lower face of hind 

 femora pale red. Hind tibia? olive-green, the spines black with a pale 

 base. Abdomen clay-yellow. Female duller, lacking the pale dorsal stripe, 

 the face in part brown, the lower face of hind femora clay-yellow. Eyes 

 more prominent in male, with interocular space obviously wider than in 

 glacialis. Antennae of both sexes much longer and more slender than 

 there. Pronotum slightly wider with metazona more evidently expanded, 

 its hind margin squarely truncate. Hind femora longer and more slender 

 than in glacialis, their tips distinctly surpassing the abdomen in male. 

 Furcula slightly shorter and more tapering. Cerci of male longer, much 

 more slender, dark brown, not black, the apex feebly widened and rounded, 

 not oblique as in glacialis; those of female much more slender, with nar- 

 rower base and more strongly tapering. Supra-anal plate of female 

 shorter, with apex deflexed instead of horizontal as in glacialis. Subgeni- 

 tal plate of male with upper margin more broadly and deeply notched 

 above the tubercle than there. Length of body, $, 16.5 20, 9, 21 26.5;
