WHEELER: ANTS OF THE GENUS FORMICA. 53D 
species of Camponotus. And, curiously enough, the shape of the head 
and the small size and flatness of the eyes in this caste remind one 
vividly of the Camponotus worker major. The male subpolita was 
originally described by Emery as a distinct species (F. rufiventris), 
but Mr. W. M. Mann has taken it on Orcus Island, Washington, 
flying (though not in copula) with females which undoubtedly belong 
to subpolita, and I have taken from colonies of this species at Pacific 
Grove, Cala., deilated females that have the color of the male, 7. e. 
with black head, thorax, and petiole and the gaster of a peculiar 
yellowish red color. 
F. subpolita nests under stones in grassy places, in Washington and 
Northern California at low elevations but ascends to considerable 
elevations (6,400 ft.) in the southern part of the latter state. The 
colonies are rather small and the workers are timid. At Point Joe, 
near Pacific Grove, I found many nests on the sea-shore and contain- 
ing great numbers of coccids and pseudoscorpionids. 
116. F. SUBPOLITA var. CAMPONOTICEPS, var. nov. 
WorKER. Length 3-6.5 mm. 
Differing from the typical form in the shape of the head and the color 
of the largest workers. The head is more distinctly rectangular than 
in the typical swbpolita, and, excluding the mandibles, slightly broader 
than long, not narrower in front than behind, except very close to the 
insertions of the mandibles, with the cheeks straight behind and con- 
vex only anteriorly. 
Sculpture of clypeus and head finer than in the typical form. 
Mandibles more superficially striated and shining. Frontal area 
smooth and shining in some specimens, opaque in others. 
Body and legs yellow or yellowish brown, the posterodorsal portion 
of the head brown, the gaster blackish brown, the mesonotum with a 
large dark brown spot, the pronotum with a paler and more indefinite 
spot. Legs clouded with brown. Mandibles bright red. Smallest 
workers dark like those of the typical form. 
TYPE LocALITy.— Washington: Wawawai (W. M. Mann). 
Washington: Rock Lake (W. M. Mann); Govan (J. A. Hyslop); 
Almota (A. L. Melander). 
The head of the maxima worker of this variety is even more cam- 
ponotiform than that of the typical swbpolita, owing to the straight 
sides and more sudden narrowing at the insertion of the mandibles. 
I am not certain that the smallest workers described as darker in 
color belonged to the same colony as the largest specimens. The 
medium workers are pale in color like the largest.
