554 WHEELER. 



The worker of this variety is much less pilose than the typical sub- 

 polita and the var. camjwnoticejjs . In color it is like the latter, with 

 the upper surface of the head darker, but the head of the largest 

 workers is not so large and rectangular and more like that of the 

 typical form of the species. 



168. Formica (Proformica) neogagates Emery. 



Utah: Promontory Point (A. Wetmore) ; Salt Lake (T. H. Parks). 



The typical form of this species is widely distributed through the 

 Transition Zone from the New England States to Washington and as 

 far north as Quebec, British Columbia and Alberta, but is not known 

 from California. 



169. Formica (Proformica) neogagates subsp. lasioides Emery. 

 Recorded from South Dakota, Colorado and Massachusetts. 



170. Formica (Proformica) neogagates subsp. lasioides var. vetula 

 Wheeler. 



California: Lake Tahoe, 6000-8000 ft. and Glacier Point, Yosemite, 

 8000 ft. (Wheeler). 



Alberta: Banff (C. G. Hewitt). - 



Colorado: Chimney Gulch, Golden 9500 ft., and San Juan Mts. 

 12,000 ft. (E. J. Oslar). 



Montana: Beaver Creek, 6300 ft. (S. J. Hunter). 



More widely distributed than the typical neogagates. All the 

 workers and females from California have the scapes even more dis- 

 tinctly hirsute than many specimens from the Eastern and Central 

 States. This ant is very common at Lake Tahoe and is the summer 

 host of Xenodusa montana Casey. I found the larvae of this beetle 

 in the nests both at Tahoe and Glacier Point, but failed to find an}' 

 pseudogynes in these localities. The winter hosts of the Xenodusa 

 are Camponotus herculeanus var. modoc and C. laevigatus. 



171. Formica (Proformica) neogagates subsp. lasioides var. limata 

 Wheeler. 



Recorded from Colorado and New Mexico. 



172. Formica (Neoformica) pallidefulva Latr. subsp. schaufmsi 

 Mayr var. incerta Emery. 



This variety, which is very common throughout the Central and 

 Atlantic States, does not extend westward beyond the Eastern slopes 

 of the Rockv Mts. It has been taken in Colorado and New Mexico.
