WHEELER: ANTS OF THE GENUS FORMICA. 551 
Both are southern forms, the true pallidefulva being very rare as far 
north as New Jersey and New York. ‘The species is very constant 
morphologically although it varies greatly in color, and pilosity. The 
males of all the forms I have seen are very slender, have very large 
eyes and resemble the males of the subgenus Proformica in having 
the stipes of the genitalia projecting considerably beyond the other 
appendages. What Mayr described as the female of pallidefulva from 
New Jersey, I believe with Emery to be the female of F. difficilis.

F. pallidefulua var. succinea Wheeler, Bull. Amer. mus. nat. hist., 1904, 20, 
p. 369, 8. 
Worker. 4.5-6 mm. 
Differing from the worker of the typical form in color, being through- 
out of a richer, purer, more reddish yellow, and in having the pubes- 
cence on the gaster even shorter and more inconspicuous. The whole 
surface of the body seems to be somewhat smoother than in the typical 
form and the integument harder. 
FEMALE. Length 8-9 mm. 
Whole body red, decidedly darker than the worker; mandibles. 
more brownish, legs more yellowish. Wings colorless, with pale brown 
veins and stigma. 
Mave. Length 8-10 mm. 
Body long and slender. Head small, with very large eyes, broadly 
rounded behind. Cheeks very short, straight. Mandibles pointed, 
edentate, their blades rather broad. Clypeus carinate. Frontal 
carinae diverging. Maxillary palpi 6-jointed. Antennae very slender. 
Thorax narrowed in front. Petiole very thick and low, with a very 
blunt border, which, seen from behind, is transverse and feebly notched. 
in the middle. Gaster long and slender. Stipes of genitalia long and 
slender, considerably surpassing the other appendages. 
Head, thoracic dorsum, and epinotum subopaque; pleurae and 
gaster shining. Hairs very short, confined to the thoracic dorsum. 
and top of head. 
Honey yellow; ocellar triangle black; mesonotum streaked with. 
brownish. Wings colored as in the female.
