344 FAMILY VI. ACRIDIDJE. THE LOCUSTS. 



DeGrassi Point and Guilford, Out., Sept. 9 Oct. 21 (Walker). 

 Scudder's types were from Ithaca and Enfield Falls, N. Y., and 

 the known range of the species extends from the Ontario stations 

 mentioned south to the mountains of North Carolina, near Bal- 

 sam and Piueola, where specimens were taken by Morse who says 

 (1904, 41) : "This locust seems to be rather widely distributed 

 in the higher parts of the North Carolina mountains, inhabiting 

 shrubby undergrowth and thickets of weeds and bushes through- 

 out the mountains. It is a sluggish and secretive species, and but 

 few examples were observed at any one point." At DeGrassi Point 

 Walker found them in swampy ground, where the vegetation was 

 of a boreal character. In such places the}' were found on bushes 

 and the branches and trunks of the Arbor-vita?, sometimes eight 

 or ten feet above the ground. Rehn (1900, 631) says that in 

 Pennsylvania they usually occur on the branches of hemlock, and 

 wherever taken have been in the vicinity of that tree. Vestal 

 (1914, 107) has recorded it from near Douglas Lake, Mich., from 

 specimens identified by Caudell. 



Scudder in his key to the species of Podisma (1897, 97) used 

 the form of the cerci and the color of hind femora as the prin- 

 cipal characters in separating this species from glacialis. Walker 

 (1903, 298) has endeavored to show that his race canadensis is a 

 connecting link between glacialis and variegata, and has used the 

 slight variation in form of cerci and color of hind femora in 

 canadensis as his principal evidence. Admitting that in canaden- 

 sis the cerci are more slender, the upper face of hind femora faint- 

 ly barred and the antennae slightly longer than in typical glacialis ; 

 the much greater length of antennse, different general hue, strong- 

 ly fasciate hind femora, squarely truncate front and hind margins 

 of pronotum, longer hind femora of male and distinctly more 

 slender cerci in both sexes of variegata present a combination of 

 characters which, taken in connection with its range and habitat, 

 lead me to regard it as more than an "incipient species" or race of 

 glacialis, and I have therefore retained it as Scudder placed it 

 as a distinct and valid species.

"to leap. 1 ') 



Slender-bodied, small or medium sized species, having the face 

 strongly oblique, occiput and vertex horizontal ; fastigium in front 

 of eyes widened and subvertical ; eyes large, elongate-oval, rather 

 prominent with the interocular area as narrow as the apex of fron- 

 tal costa, male, depressed, tapering above and with interocular
