206 Psyche [December 



I. and Neapisca I. (Saml. Henshaw); East Maine R. (A. Skinner). 



Nova Scotia: Digby (J. Russell). 



Newfoundland: Bay of Islands (L. P. Gratacop.), Spruce Brook, 

 Port Saunders, Port au Croix (Amer. Mus, Nat. ITist.); Seldome 

 Come Bay, Fogo I. (O. Bryant). 



Labrador: Square I. (A. S. Packard); St. Lewis Inlet. 



The varieties neorvfiharhis, gelicla and algida are all very closely 

 related boreal fusca forms, the first, as I have noticed during the 

 past summer, common in the Sierra Nevada Mountains, Selkirks 

 and the Canadian Rockies at elevations between 4,000 and 5,000 

 feet, the second ranging from Alaska to higher elevations in the 

 Sierra Nevada and Rocky Mountains of Colorado and New Mexico, 

 and the last peculiar to boreal eastern North America, where it 

 occurs at low elevations from Labrador to New York and as far 

 west as Western Ontario, but, so far as know n, only in peat bogs 

 within the United States. 



Besides F. fusca var. algida there are several species of ants that 

 nest frequently or by preference in the cold bogs of the Northern 

 States and British America. The most frequently met with in 

 such situations are, according to my observations, the follow^ing: 

 Myrmica brevinodis Emery vars. canadensis Wheeler, and sulci- 

 nodoides Emery, Myrmica scabrinodis Nyl. var. detritinodis Emery 

 and subsp. schencH Emery var. emeryi Forel, Leptothorax (Mycho- 

 thorax) emersoni Wheeler and its subsp. glacialis Wheeler, Crema- 

 togaster lineolata Say and its subsp. pilosa Pergande, Dolichoderus 

 {Hypoclinea) taschenbergi Mayr var. aterrimus Wheeler, Lasius 

 niger L. vars. sitkaensis Pergande and neoniger Emery, Lasius 

 {Chthonolasius) umbratus Nyl. subsp. minutus Emery, Formica 

 fusca L. (typical), Formica cinerea Mayr vars. neocinerea Wheeler 

 and altipetens Wheeler, Camponotus herculeanus L. var. ivhymperi 

 Forel and subsp. ligniperda Latr. var. novehoracensis Fitch. In 

 the bog at Petersham, Mass., a worker major of Camponofus whym- 

 peri w^as found in the liquid contents of a pitcher plant leaf (Sar- 

 raceyiia purpurea) . It is probable that this list will be considerably 

 increased by further attention to the ants inhabiting our northern 

 peat-bogs.
