516 WHEELER. 



56. Ajihacnogaster subterranea subsp. valida Wheeler. 

 Recently described from Cheyenne Canyon, near Colorado Springs. 



57. Aphaenogaster subterranea subsp. valida var. manni var. nov. 

 Worker. Length 4-5 mm. 



Differing from the typical valida in color, the body and antennae 

 being yellowish brown throughout, the mandibles, clypeus, and legs 

 paler and clearer yellow. The sculpture of the epinotum and meso- 

 pleurse and sides of the pronotum much feebler and the upper surface 

 of the pronotum more shining. 



Numerous workers from Pullman, Washington, (W. M. Mann). 

 Other workers from the same locality but from different nests have 

 the head and gaster darker than the thorax and thus represent transi- 

 tions to the typical valida. 



58. Aphae7iogaster subterranea subsp. borealis Wheeler. 

 Recently described from worker specimens taken by Prof. J. C. 



Bradley at Lardo, Kootenay Lake, British Columbia. A number of 

 workers taken by Dr. C. G. Hewitt at Arrowhead Lake, British 

 Columbia, though slightly darker, are also referable to this subspecies. 



59. Aphaenogaster patruelis Forel. 



Known only from the Island of Guadeloupe off the coast of Lower 

 California. 



60. Aphaenogaster patruelis var. bakeri Wheeler. 



This variety was taken several years ago on Catalina Island off 

 the coast of Southern California by Prof. C. F. Baker. 



61. Aphaenogaster patruelis var. carbonaria Pergande. 

 According to Forel, this form, originally described as a species, is 



merely a somewhat darker and more coarsely sculptured variety of 

 patruelis. The types were taken by Eisen at Sierra Laguna and El 

 Chinche in Lower California. 



62. Aphaenogaster mutica Pergande. 



Known from Lower California, Northern Mexico and Western 

 Texas.
