2. NEW DATA ON THE ECOLOGY OF 
APHAENOGASTER HUACHUCANA 
AND A DESCRIPTION OF THE SEXUAL FORMS

In 1932 the writer presented, in this journal, a descrip- 
tion of the worker of Aphaenogaster (Attomyrma) huachu- 
cana (1). The type specimens came from a single nest 
taken at an elevation of about 7000 feet in Ramsey Canyon 
in the Huachuca Mountains. I expected that other workers 
would find additional material of huachucana and that this 
would permit a better evaluation of its status, for huachu- 
cana is clearly related to texana. Since the latter species 
is also present in the Huachucas, much might be learned 
from the way in which the two insects behave in that area. 
In 1950 I synonymized Wheeler’s variety furvescens with 
texana (2). The variety furvescens, which was based on 
material coming from the Huachucas, had proven to be a 
color phase that occurs over the entire range of texana. 
The synonymy of this variety raised disturbing possibilities 
in the case of huachucana, for there was a chance that it 
might also prove to be an inconsequential variation of 
texana when better known. In order to test the significance 
of the structural features on which huachucana was based, 
more material was urgently needed. This material has 
now come to hand and with it field data which provide 
good evidence that huachucana is a separate species. In 
order for this evidence to be appreciated it is necessary
