change in the name. But after considering such names as " the forest 

 caterpillar," " the forest Clisiocampa," " the spotted forest caterpillar," 

 "the maple Clisiocampa," I was unable to suggest any good substitute 

 for the old name. Recently, however, while again cogitating on the 

 subject, the name of " forest tent/gss caterpillar '" suddenly appeared on 

 the horizon of my thoughts. It seemed hardly the thing at first, but the 

 more I thought of it the more appropriate it seemed. I brought the name 

 before the Entomological Club, the Jugata?, here at Cornell University, 

 and all agreed it was a very apt and easy way to solve the problem. The 

 name of "forest tentless caterpillar" retains all of the "old associations : " 

 it is not a radical nor a difficult change to become accustomed to, and it 

 expresses the characteristic difference between the habits of the cater- 

 pillar and those of the apple tent-caterpillar. I would therefore here 

 propose that Clisiocampa disstria be properly known as the forest tentless 

 caterpillar. Are there any serious objections to this name, or has anyone 

 a better one to suggest? M. V. Slingerland, Ithaca, N. Y.

Professor J. B. Smith, of New Brunswick, N. J , first reported this 

 grasshopper in this section, as occurring in cranberry bogs in New Jerse}-. 

 In 1896 specimens were taken by Mr. ^^^ H. Wensel, of Philadelphia, in 

 Southern Philadelphia ("the Neck") ; by Mr. S. T. Kemp, of Elizabeth, 

 N. J., at Camden, N. J. 3 and by Mr. C. Fen Seiss, of Philadelphia, on 

 August 26th, the latter on a window-sill in the centre of the city. Mr. 

 Seiss has in his collection four specimens taken in 1897, on August 2nd, 

 September nth (two specimens), and November 6th — all from Phila- 

 delphia. The writer secured five specimens on September 5th and t ith 

 at League Island and Philadelphia Neck, Philadelphia Co., Penn. They 

 were collected on the large leaves of weeds, except one taken on a 

 cement walk. In the same year specimens were taken at Riverton, Bur- 

 lington Co., and Westville, Gloucester Co., N. J., by Mr. H. L. Vienck. 

 Ill 1898 they first appeared mature about August ist, in the streets, on 

 lots, and even in the iron manufacturing sections of the city, where there is 

 absolutely no vegetation. Their number was greatly increased, and they 

 appeared to be firmly established. The year 1899 presented this species 

 as a rather common grasshopper from August to October, with all the 

 territory surrounding this city occupied by it. The range of this species 

 this far east (Smith's record) was doubted by Scudder (Rev. Melan., p. 

 353), but he adds in a foot-note that he later noticed specimens in the 

 collection of the American Entomological Society of Philadelphia from 

 Camden Co., N. J. The range of this species to the north or south of 

 this section I do not know, but I think it has come east to stay, as it 

 seems to take possession of everything and thrive in its new location.
