ginous pile only on its apical margin. Numerous specimens from 

 British Columbia and Montana. 



Color Variant 5 . — {nearcticus Ant. Handlirsch and cooleyi Morrill, 

 pars.). Queen and worker like Color Variant 2, but with dorsal seg- 

 ments two and three entirely black — typical worker {edwardsii Cres- 

 son). Numerous specimens from British Columbia, Montana and 

 Alaska. 



Male Color Variant I. — [edwardsii Cresson). The typical form de- 

 scribed above. Many specimens from British Columbia and Montana. 



Male Color Variant 2. — {vancouverensis Cresson, pars.). Like Male 

 Color Variant 1, but with sides of dorsal segment three bearing ferru- 

 ginous pile. Four specimens from British Columbia. 



Male Color Variant 3. — Like the first two male color variants, but 

 with the second and third dorsal abdominal segments entirely covered 

 with ferruginous-red pile. Specimens from British Columbia and 

 Colorado. 



Male Color Variajit 4. — Like Male Color Variant 1, but with second 

 dorsal abdominal segment entirely covered with yellow pile. Two 

 specimen from California. 



While I have not seen enough material from all parts of 

 the habitat of this species to be sure of my ground, I believe 

 that sufficient collecting is likely to show that those color 

 variants with the second and third dorsal abdominal seg- 

 ments largely covered with ferrugionus-red pile are much 

 more numerous in the southern part of its range (Colorado, 

 Utah, Nevada, California and New Mexico) while those 

 color variants which have these segments mostly black are 

 much more numerous in the northern part (Alaska, British 

 Columbia, Alberta, Mantana, etc.) — this is evidenty the case 

 in Montana and Colorado and only the nearcticus form has 

 been taken in Alaska. As will be seen, this apparent char- 

 acteristic is closely paralleled in the case of flavih^ons and 

 rufocinctzis. 



Habitat. — I have records of this species from Alaska 

 (southern), British Columbia, Alberta, Vancouver Island, 

 Washington, Idaho, Montana, California, Nevada, Utah, 

 Colorado and New Mexico. It must be present also in 

 Oregon and Wyoming. My most northern record is Juneau, 

 Alaska ; most eastern, Garden of the Gods, Colorado ; most 

 southern, Beulah, New Mexico. In our western states, it
