52 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 
Smooth and shining; mandibles shining, not striate but sparsely 
punctate, like the remainder of the body. Punctures on the head 
coarser than in hedleyi, and more abundant, especially on the cheeks 
and sides of the front. Clypeus subopaque, rugulose-punctate. 
Hairs similar to those of hedleyi but coarser and of rather uneven 
length, pale yellow. 
Rich ferruginous red, clypeus darker; tarsal claws, sutures of thorax 
and gaster, articulations of antennal funiculi dark brown, mandibular 
teeth black; legs and anal segments of gaster paler and more yellowish. 
Female. Length nearly 5.5 mm. 
Head a little longer than broad and nearly as broad in front as long, 
with prominent, depressed anterior corners, the sides converging 
posteriorly, with two transverse impressions, one half-way between 
the anterior corner and the eye and oneat the eye. Eyes as small as 
in the worker, but more elongate. Mandibles with less abruptly 
incurved tips than in the worker and with only two indistinct teeth. 
Thorax more robust than in the worker, the pro- and epinotum with 
more convex sides and the pronotum more convex above, so that the 
mesonotum is more impressed in profile. From above the mesonotum 
is scarcely twice as broad as long. Petiole much larger than in the 
worker, with very short, slender peduncle, without ventral projec- 
tion; node large, very convex in front, from above more than twice 
as broad as long, broader than the epinotum and nearly half as broad 
as the postpetiole. Gaster very much larger than in the worker, 
more than twice as long as broad, suboblong, flattened dorsoventrally. 
Sculpture as in the worker, but the piligerous punctures, especially 
on the head, much coarser, almost foveolate and somewhat elongated 
on the sides of the front. Cheeks and sides of epinotum subopaque, 
finely rugulose-punctate. 
Hairs coarser and longer, especially on the body, than in the worker. 
Color more brownish ferruginous; mandibles, antennae, and legs 
more yellowish; pleurae, sides of petiole, and sutures of gaster brown- 
ish yellow.

October 24, I found two fine colonies of this species in rotten logs. 
One comprised at least 400 workers, a single queen, with the abdomen 
greatly distended with eggs, and a large number of nearly mature 
larvae but no pupae. The other colony was somewhat less populous 
but also contained many larvae. The ants moved rather slowly in 
long files through the cracks in the wood, evidently endeavoring to
