TWO NEW MELANOPLI FROM LES CHENEAUX ISLANDS, 

 MICHIGAN. 



BY W. S. BLATCHLEY, INDIANAPOLIS, INDIANA. 



In August, 1897, after attending the 

 meeting of the Economic Entomologists 

 at Detroit, Michigan, I made a trip by 

 boat via Mackinac Island to Chicago. 

 From Mackinac, one of the most enjoy- 

 able and popular excursions is to the 

 Snow (Les Cheneaux) Islands lying 

 12 miles to the northeast, near the 

 northern shore of Lake Huron. These 

 islands are a picturesque group, one 

 hundred or more in number, covered 

 with primitive vegetation, and sepa- 

 rated by narrow channels. On several 

 of the islands suminer hotels are 

 erected and are patronized by many of 

 the disciples of Izaak Walton, who find 

 in the network of channels the finny 

 tribe in untold numbers. 



La Salle Island, on which I spent 

 a day, is one of the largest of the group 

 — probably a mile and a half long by 

 a half mile or more wide — densely 

 wooded with spruce, hemlock, cedar, 

 pine, birch and aspen, and with its 

 shores abrupt and in most places 40 to 

 50 feet above the water level. Only 

 along the immediate shore in front and 

 on either side of the Elliott House have 

 any clearings been made. Here, Cir- 



cotcttix vemiciilatiis (Kirby), Catn- 

 nula pelhicida (Scudd.), Alelanoplus 

 bivittatiis (Say), M. atlanis (Riley) 

 and AI. femur-rubrtim (De Geer) 

 were plentiful. In one or two other 

 localities were secured small numbers 

 of two additional species which have 

 proven to be undescribed, and which, 

 therefore, form the basis of the present 

 paper.
