It has also been reported from (Quebec (Provancher, Scudder; Dodge 

 County, Nebraska (Dodge), and the Mackenzie River, British America, 

 at latitude 05° (KirLy); the last, however, is uncertain, dependingon the 

 determination of Kiiby's species. It probably occurs throughout the 

 larger part ol Canada and the northernmost United States. 



As indicated in the deseiiption, this insect appears in two forms: a 

 short winged (J/. e.jiiniuH), in which the tegmina at rest do not reach 

 the tips of the hind i*emora: and a long-winged (for which 1 propose 

 the name M. e. ncandens), in whu;h Ihey surpass them, generally con- 

 siderably. The latter has also a slightly slenderer body, though the 

 difference is not marked. It appeals to affect high latitudes and alti- 

 tudes, being found in all the localities in the high north where Kennicott 

 collected, on the Big Horn Mountains in W^yoming. and on the summits 

 of Greylock in Massachusetts, and the White Mountains in New Hamp- 

 shire, in all of which (unless in Wyoming, wlir:ice I have only seen two 

 specimens) it is the prevailing or exclusive form. The short-winged 

 form, however, occurs in all these places excepting the Aljnne region of 

 the White Mountains, where it has not been taken ; and the long winged 

 occurs also at lower levels in New England, as at North Conway, New 

 Hampshire, Jay and Montgomery, Vermont, and Winchendon, Massa- 

 chusetts, but it is only found in these places exceptionally, to judge 

 bom the specimens seen. The two specimens from the Big Horn 

 Mountains, the male scandens^ the female Junius, are of exceptional 

 size, and Arctic American specimens are also distinctly larger thaiL 

 those from New England or Nebraska.
