Color as in the worker major, but the anterior border of 
the pronotum and the mesonotum about the wing insertions 
more or less ferruginous red. Wings long (nearly 10 mm.), 
faintly brownish and rather opaque, with pale brown veins; 
pterostigma with a long hyaline area in the middle. 
Male. Length 5 mm. 
Head, including the eyes and mandibles, a little longer than 
broad, broadly and semicircularly rounded behind. Cheeks 
straight and subparallel. Eyes large and convex. Clypeus 
rather convex, broader than long, with straight, entire an- 
terior border. Mandibles small and rather broad, with 
only the acute apical tooth developed. Antennze very slender, 
the scapes terete, reaching only two-fifths their length beyond 
the posterior border of the head. Thorax broader than the 
head, mosonotum as broad as long, subhexagonal. Epinotum 
resembling that of the female. Petiole thick and low, sub- 
cuboidal, with flattened dorsal surface, seen from above trans- 
versely oblong, twice as broad as long. Gaster somewhat 
flattened dorsoventrally, with very slender genital appendages. 
Legs very slender. 
Sculpture like that of the female; head, including the man- 
dibles, subopaque; thorax and gaster more shining, densely 
and very finely shagreened, except the mesonotum and scutel- 
lum, which are more sharply shagreened and subopaque. 
Hairs grayish, much less abundant than in the worker, 
absent on the thorax and almost absent on the head. Pubes- 
cence very feebly developed, even sparser on the gaster than 
in the female. 
Black or dark brown; mandibles dull yellowish, anterior 
portion of head and clypeus, antenne, epinotum, thoracic 
sutures, petiole, legs and tip of peste more piceous. Wings 
colored as in the female. 
Described from 10 major workers, five minor workers, three 
females and a single male taken during October 1905 by Dr. 
F. X. Williams from a single colony at Cormorant Bay, 
Charles Island. The label bears a note that the species is 
“common in old logs’. I have also before me 18 well- 
preserved males taken by the “Albatross” on the same island 
(ace. 21,699, U. S. Nat. Mus.).
