 Allen; Jefferson, Green County, Iowa, July 20-24, Allen; Crawford 

 County, Iowa, prairies, July 13-24, Allen; Denisou, Crawford County, 

 Iowa, July 20, Allen; Big Horn Mountains, Wyoming, 8,000 to 9,000 

 feet (L. Bruuer); Arctic America, Kennicott; Great Bear Lake, Ken- 

 nicott; Upper Mackenzie River, Kennicott; Yukon Eiver, at mouth of 

 Porcupine River, Alaska, Kennicott; Banff, Alberta, Bean(S. Henshaw). 



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

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

 at latitude 65 (Kirby); the last, however, is uncertain, dependingon the 

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

 larger part of Canada and the northernmost United States. 



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

 short winged (M. e.junius), in which the tegmina at rest do not reach 

 the tips of the hind femora; and a Jong- winged (for which I propose 

 the name M. e. scandens), in which they surpass them, generally con- 

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

 difference is not marked. It appears 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 Wyoming, and on the summits 

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

 shire, in all of which (unless in Wyoming, whence 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 Alpine 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 

 from 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 than 

 those from New England or Nebraska.
