pronotum, covering slightly less than half the abdomen, their tips nar- 

 rowly rounded. Hind femora short, reaching or slightly surpassing tip of 

 abdomen, male, distinctly shorter than abdomen, female. Supra-anal plate 

 short, triangular, the basal median ridges uniting slightly beyond the mid- 

 dle and continued as a single ridge to the rounded apex, the median sulcus, 

 therefore, confined to the basal half; furcula consisting of a pair of short, 

 blunt, widely separated, finger-like projections lying just outside the me- 

 dian sulcus. Cerci with basal third swollen, strongly tapering, apical two- 

 thirds equal, very slender, feebly curved forward and inward, the apex

This dull colored robust locust was originally described from 

 a score or more of specimens taken by me at LaSalle Island, Mich., 

 Aug. 17, 1897. They were found for the most part in a small clear- 

 ing an acre or more in extent, where a cabin had formerly stood. 

 Along its margins and over part of its area grew clumps of the 

 wild red raspberry, Rnbus strigosas Michx., and among the numer- 

 ous remains of stumps were small bunches of wire-grass and the 

 trailing vines of the dewberry. Here M. huroni had its home, and 

 the females, leaping lubberly from one bunch of grass to another, 

 were readity secured, but the more sprightly males would often 

 have to be chased quite a distance before their capture was 

 effected. Specimens were sent Scudder for examination, and he 

 reported them as unknown to him. The species was then de- 

 scribed as Melanoplus huroni and under that name was recorded 

 by Rehn (1904d) and Hebard (1909) from Pequaming, Mich., and 

 by Morse (1909) from Isle Royale. Caudell (1903, 798) placed it 

 as a synonym of M. altitudiinuit Scudd., a species ranging from 

 South Dakota and Wyoming to New Mexico. It was recorded 

 under that name by E. M. Walker (1909, 207) as occurring at Ft. 

 William and Nipigon, Ontario, both brachypterous and macropter- 

 ous specimens having been found in open scrubby woods on the 

 top of Mt. McKay. Hebard (who has been making an exhaustive 

 study of the Melanopli) informs me that both huroni and altitudi- 

 num are distinct and valid geographic races of Melanoplus (Pod- 

 isnia) clodfjei (Thos.), a common and widely distributed alpine 

 species of the Rocky Mountain region and as such, on Hebard's 

 authority, it is listed above. The records noted above are all that 

 can be found of its occurrence in the territory covered by this 

 work.
