Duzee* published a list of the species of Hemiptera knoAvn to 

 occur in the Adirondacks. The latter, based on a few days' col- 

 lecting at Lake Placid and Saranac Lake Junction in 1902 and 

 the forms enumerated by MacGillivray and Houghton, contains 193 

 species of Hemiptera (92 Heteroptera and 101 Homoptera). 



The present list enumerates 397 species and varieties of Hemip- 

 tera, 218 Heteroptera (one lygaeid not determined), and 179 

 Homoptera. All the species are from the vicinity of Cranberry 

 Lake and 95 per cent or more of the forms occurring in this region 

 have been taken on about 200 acres of the Barber tract. How- 

 ever, this portion of the tract is represented by a marked variety 

 of ecological and biological conditions. It includes camp site, 

 hills, marshes, bogs, beaver meadows, lumbered areas, forests, tote- 

 roads, trails, open areas, dense growth of j^oung trees, burned- 

 over areas, coves of Cranberry Lake and the like. The following 

 species, listed by Van Duzee, have not been taken in the vicinity 

 of Cranberry Lake:
