 While collecting at North Bay, Lake Nipissing, on Sept. 12, 1900, I 

 took 10 o* s and 5 ^ s of this insect. They differ slightly from the typical 

 glacialis of the White Mountains, approaching P. variegata to a slight 

 degree in several points. Having compared them with two pairs of 

 typical glacialis from New England, and noticing these peculiarities, I sent 

 a few specimens to Mr. Scudder, who says that they are " without doubt 

 glacialis, though varying slightly towards variegata, especially in the 

 (feebly) banded hind femora." He also notes that " the cerci of the J 

 are more smoothly rounded at the apex and the furcula shorter than in 

 typical glacialis." As compared with my New England specimens, they 

 also differ in having in every case distinctly longer antennae and hind 

 femora, and in the more prominent eyes ; in all of these characters 

 approaching variegata. 



In the White Mountains Mr. Scudder has found this species on the 

 dwarf birch ( Betula nana), while Mr. Morse has found it most common 

 in the various species of Vaccinium characteristic of mountain tops, and on 

 dwarf cornel. Most of my specimens were found on red raspberry bushes, 

 like P. variegata, at Lake Simcoe, but many were also seen on alders. 

 Unlike variegata, they are not confined to swamps, but are also found 

 in comparatively dry places. 



I have two immature males of a Podisma, probably this species, 

 collected by Mr. G. M. Stewart on the portage between Lakes Esnogami 

 and Kabinakagami, in Northern Ontario. This portage is across the 

 Height of Land, and is a little further north than the species has hitherto 

 been recorded. One of the specimens is almost full-grown, and in both 

 the hind femora are pale yellow, strongly banded with black. They are 

 dated July 12 and 13, 1900.
