1915.| Wheeler, Additions to the Ant-Fauna of North America. 407 
of the latter, which is smooth and shining. Gaster shining, with fine, sparse, piliger- 
ous punctures. 
Pilosity similar to that of the soldier but shorter and more uniform; hairs on the 
legs and antennal scapes more appressed. 
Rufotestaceous; legs somewhat paler; mandibles, gaster and anterior portion 
of head darker and brownish, posterior margins of gastric segments yellowish. 
Described from numerous soldiers and workers and one female from the 
following localities in California: Palo Alto (H. Heath and W. M. Mann 
and Wheeler); Brookdale and Santa Cruz Island (R. V. Chamberlin). 
The type locality 1s San Francisco (Schaufuss). 
26. Pheidole californica Mayr var. incenata var. nov. 
Slightly smaller than the typical form and differing in color, the whole body 
being yellow in the soldier and worker, except the mandibles and sides of the clypeus 
in the former, which are red, and the top of the head of the latter, which is some- 
what infuscated. 
Nine soldiers and as many workers taken By Prof. H. Heath at Palo 
Alto, California. 
27. Pheidole californica Mayr var. satura var. nov. 
Fully as large as the type but differing from it and the var. incenata in color. 
The soldier has the mandibles, head, thorax, and pedicel deep chestnut brown, the 
borders of the mandibles and the gaster black, the legs brownish yellow with the 
middle portions of the femora infuscated. The worker has the head, gaster and 
pronotum deep castaneous, the remainder of the thorax, mandibles, the pedicel 
clypeus, antenne and legs brownish yellow, the femora darker, except at their bases 
and tips. 
Described from numerous soldiers and workers taken on Santa Cruz 
Island, California, by Dr. Ralph V. Chamberlin and at Palo Alto, Cala., 
by Prof. H. Heath. 
28. Pheidole californica oregonica Lmery. 
Emery described this ant as a species, but I believe that it is no more 
than a subspecies bearing the same relation to the typical californica that 
the typical Ph. vinelandica Forel bears to its subspecies longula Emery. 
The head of the oregonica soldier is distinctly shorter in proportion to its 
width than that of californica, and the frontal and occipital rugee are sharper
