teeth than spines. In furvescens the spines, while only 
slightly longer than those of huachucana, are slender 
throughout and not tooth-like. Finally the sculpture of 
huachucana is uniformly heavier than that of furvescens. 
The ecological differences are equally distinct. The nest 
from which the types of huachucana were secured was 
situated at the base of a rocky ledge above a very steep slope 
on the western side of the canyon. The arrangement was 
such that the nest was in the shade for the greater part of 
the day. The elevation, as has been already noted was 7000 
feet. I have taken many colonies of furvescens both in Ram- 
sey and Miller Canyons. These were invariably under stones 
in sunny situations not far removed from the stream bottom 
and at elevations not exceeding 6000 feet. Finally the ac- 
tions of huachucana are quite different from those of fur- 
vescens. The insects are slow, one might almost say clumsy, 
in movement even when excited, a marked contrast to the 
active and energetic workers of furvescens. 
On the last day of May 1932 one of my students, Mr. Solo- 
mon Friedland, while collecting along the top of the Pali- 
sades near Englewood, N. J. had the good fortune to secure 
a single female belonging to the genus Anergates. At that 
time I considered the insect identical with the European 
atratulus but subsequently, through the generosity of Dr. 
W. M. Wheeler, I have been enabled to compare it with speci- 
mens of atratulus collected by Dr. Wheeler in Switzerland. 
This comparison has revealed a surprising number of signi- 
ficant differences and I now feel that the insect taken by 
Mr. Friedland must be regarded as a new species. Mr. 
Friedland’s discovery is of twofold interest for it not only 
gives us first record of Anergates in the New World but 
also furnishes important data on the distributional status 
of the host species Tetramorium cxspitum. This matter is 
discussed in detail at the end of the following description.
