Wohin IE, lee, 28) WHEELER—GALAPAGOS ISLANDS ANTS 281 
and the four segments of subequal length. Legs moderately 
long, the fore femora somewhat enlarged. 
Smooth and shining, very finely and delicately shagreened ; 
mandibles, clypeus and head slightly subopaque, covered with 
minute, shallow punctures, which are densest on the mandi- 
bles. Pro- and mesonotum with a few elongate, shallow 
foveole above. 
Hairs pale yellow, erect, very sparse and rather short, con- 
fined to the dorsal surface, the venter and the tips of the 
scapes and femora. Pubescence pale, short and dilute, distinct 
only on the legs and antenne. 
Brownish yellow, legs pale yellow; mandibles, scapes and 
tarsi reddish, the mandibles with narrow blackish borders. 
Front, vertex and sides of meso- and epinotum clouded with 
brown and each gastric segment with a broad dark brown 
band across its posterior surface. This band expands in the 
middle to form a rather broad streak which reaches to the 
anterior border of the segment. 
Worker mimor. Length 4.5—5.5 mm. 
Resembling the worker major, but the posterior corners of 
the head are much more rounded, the clypeus is trapezoidal 
and scarcely longer than broad and the antennal scapes extend 
about one-quarter their length beyond the posterior corners of 
the head. The puncturation of the head is less distinct than in 
the worker major so that this region is more shining. In 
other respects the sculpture, pilosity and color are very similar. 
Female. Length 8—8.5 mm. 
Closely resembling the worker major but the head is 
smaller and more narrowed in front, with the antennal scapes 
extending about one-sixth their length beyond its posterior 
corners, the petiolar node is thicker and much blunter, with its 
upper margin more transverse and very feebly impressed in 
the middle. The thorax is rather long and narrow, though 
as broad as the head, the mesonotum as long as broad. Wings 
long (nearly 9 mm.). 
Sculpture, pilosity and coloration very much as in the 
major worker. Wings distinctly yellowish, with pale brown 
veins and pterostigma. 
Male. Length 6 mm.
