Creighton — Pogonomyrmex huachucanus 
73 
huachucanus, like that of many other species which occur 
in southern Arizona, takes place during the rainy season 
of July and August. 
We may now consider the distribution of huachucanus . 
Presented below are the previously published locality 
records for this species and those which the writer secured 
during 1950 and 1951. The elevation of each of the first 
thirteen localities has been checked with U.S. Geological 
Survey topographic sheets. In addition, many of them 
have been rechecked with an altimeter as well. The last 
four localities have been checked against data in Stieler’s 
Handatlas. 
Huachuca Mountains, Arizona : Miller Canyon 5600' 
(Type locality) W. M. Wheeler; Garden Canyon 5800', W. 
S. Creighton; Carr Canyon, 5400', W. S. Creighton; Pyeatt 
Cave, 5500', W. S. Creighton; one mile east of Panama 
Mine, 5300', W. S. Creighton; Montezuma Pass, 6700', W. 
S. Creighton. 
Santa Rita Mountains, Arizona: Mouth of Madera Can- 
yon, 4800', W. S. Creighton; Sweetwater, 5800', W. S. 
Creighton. 
Santa Catalina Mountains, Arizona: 1 Sabino Basin, 3700', 
W. M. Wheeler. 
Dragoon Mountains, Arizona: Texas Pass, 4700', W. M. 
Wheeler. 
Whetstone Mountains, Arizona: Dry Canyon 5000', W. S. 
Creighton. 
Baboquivari Mountains, Arizona: Brown Canyon 4200- 
6000', W. S. Creighton. 
Oracle, Arizona, 4500', W. M. Wheeler. 
Seligman, Arizona, 5500', A. C. Cole. 
Springerville, Arizona, 5600', W. S. Creighton. 
Sixteen miles west of Socorro, N. M., 5300', W. S. 
Creighton. 
Needles, California, 460', A. C. Cole. 
From these records it can be stated that huachucanus 
usually occurs between the 4000 and 6500 foot levels and, 
since this is the case, it is clear that Dr. Cole’s record 
from Needles is badly out of line in the matter of elevation. 
1 This record is cited as “South Catalina Mountains” in Olsen’s 
monograph.
