1951 J Creighton — Arizona Ants 59 
males examined showed no bluish reflections on the gaster 
or thorax. 
The above descriptions, as well as the figures were based 
upon material taken in Garden Canyon in the Huachuca 
Mountains of Arizonia. Garden Canyon, therefore, becomes 
the type locality for the female and media worker. In this 
connection it seems well to note that there is no good agree- 
ment as to the exact situation of Palmerlee, the type lo- 
cality of the major of ulcer osus. I regret that this name 
was incorrectly spelled as “Parmerlee” in my 1950 publi- 
cation on North American ants, for this adds further con- 
fusion to an already confusing situation. Mr. L. F. Byars, 
who is much interested in Arizona ants, writes me that the 
former postoffice of Palmerlee was situated on the Palmer 
Ranch at the mouth of Miller Canyon. But Will C. Barnes 
in his entertaining publication Arizona Place Names , (6) 
states that Palmerlee was at the Reef Mine on Miller Creek 
and that J. L. Palmerlee, on whose land the postoffice was 
established in 1904, was its first postmaster. Mr. Barnes 
secured his data from the records of the United States Post 
Office, hence the date and the postmastership appear beyond 
dispute. But it is very unlikely that the postoffice was at 
the Reef Mine. For the Reef Mine is now situated, and 
apparently has always been situated, at an elevation of 6700 
feet near the head of Carr Canyon. This area is well above 
the ordinary vertical range of ulcerosus. The contradictions 
just discussed need occasion no difficulty if one is content 
to cite the Huachuca Mountains as the type locality for 
ulcerosus. 
Since virtually nothing has been published on the habits 
of ulcerosus. I wish to present certain data which were se- 
cured last summer. The observations which follow were 
made in an area near the picnic grounds in Garden Canyon. 
At this level the canyon is divided by a low ridge into two 
roughly parallel valleys. The road to the picnic grounds 
runs through the larger valley which lies to the southeast 
of the ridge. This valley is clearly the better watered 
of the two, for it contains big sycamores and junipers along 
the stream bed. These are absent in the smaller valley 
which lies on the northwestern side of the ridge. The di-
