LaSalle Island, Midi.; Steuben Co., Ind., August 1110 (\Y. 

 X. />.) ; DeGrassi Point, Out. (Walker}. The types of this species 

 were taken by me on LaSalle Island, Aug. 17, 1897. They were 

 found about the borders of a small clearing and along a narrow 

 pathway through Ihe dense spruce, birch and hemlock woods. 

 AVhen approached they would leap from the pathway into the 

 mosses and liverworts bordering its sides, and there remain quiet 

 while the intruder passed by. None were found at a distance of 

 more than ten feet from this pathway, though especial search was 

 made for them. On several subsequent visits to this and adjacent 

 islands they were found fairly plentiful in similar habitats. Other 

 locusts taken with them were Circotetti.r rcrmcnlfitus (Kirby), 

 Jfclanoplus dodgci Jiuroni 151., and Cannuila pclhn-ida Scudd. A 

 single male of isl<tndi<-us was taken from a path in a partly 

 drained tamarack marsh near the border of Clear Lake, Steuben 

 Co., Ind., Aug. 11. 1905. 



Outside of these localities typical ixldndiciis has been recorded 

 only from DeGrassi Point, Ft. William, Aurora, Toronto and 

 Georgian Bay, Ontario, and near Pequaming, Douglas Lake and 

 Porcupine Mountains, Mich. At DeGrassi Point and Aurora 

 Walker took his types of M. uliortini* (Can. But. 189S, 92), a 

 synonym of island'n-itx, "from openings in rich shady woods and 

 on their borders, especially where the timber is of a coniferous 

 growth. Seldom more than one or two were seen at once, though 

 by diligent search specimens can be secured almost any day dur- 

 ing the proper season, which lasts from the first week in July 

 to the beginning of October.'' Near Pequamiug Hebard (1909) 

 found island inis scarce and very local in distribution, only one 

 colony of any size being found during three summers' collecting. 

 This was in a growth of small hardwood trees. At Douglas Lake, 

 Vestal (1914) took it in deep moist forests of beech, maple and 

 hemlock, July 2(3 Aug. 12.
