features are within the extremes of the range of variation 
of verified subintegra. We have tentatively associated with 
ivheeleri a series from Madison Junction, Yellowstone 
Park, Wyoming, 6800 feet (E. 0. Wilson). The queens 
are smaller than eastern subintegra at our disposal and 
appear darker despite their teneral condition. The workers 
differ from the ivheeleri types by the possession of a 
shallower clypeal notch and “puberula” pilosity type (see 
under subintegra). A queen collected with workers by 
A. C. Cole at Dailey Canyon, Beulah, New Mexico, 8000 
feet, is intermediate between the Yellowstone series and 
eastern subintegra in size and color. We have not been 
able to see a syntype queen of ivheeleri, but judging from 
Creighton’s description alone, the gap between wheeleri 
and subintegra appears to be filled by the Yellowstone 
and Dailey Canyon series. Future collecting in the Rockies 
and Great Basin may reveal that ivheeleri is nothing more 
than one of the western variants of subintegra. 
The Obtusopilosa Complex of the Neogagates Group 
In the light of their new association with F. neogagates 
and relatives, the obtusopilosa group species must now 
all be re-evaluated. It is possible that some additional 
synonymy previously obscured by the false Raptif ormica- 
Proformica dichotomy will be established when the neoga- 
gates group meets its first comprehensive revision. Such 
revision is not attempted here.

Formica bradleyi Wheeler, 1913, Bull. Mus. Comp. Zool. 
Harv., 53: 423-425; worker, male. Type locality: 
Georgetown, Colorado. 
Formica ( Proformica ) neogagates var. morbida Wheeler, 
1913, ibid., pp. 538-539; worker, queen. Type locality: 
Lenox, Iowa. Synonymized under F. neogagates Emery 
by Creighton, 1950, p. 459. New Synonymy. 
Syntypes of bradleyi and morbida in the Museum of 
Comparative Zoology have been compared, and are closely 
similar, corroborating Dr. Buren’s findings. F. bradleyi
