I believe that this form, too, should rank as a subspecies and not as a 
variety of rubicunda. Emery mentions workers from Beatty, Pa., 
which were transitional in the shape of the head and petiole between 
rubicunda and subintegra. I have seen similar specimens from a few 
of the localities recorded above, but such specimens in pilosity and in 
the brown color of the gaster are always easily referable to the latter 
subspecies. The smaller size, the peculiar color of the gaster, the more 
rounded shape of the head, the narrower, thicker, and blunter petiole 
of the worker, and the absence of mandibular teeth in the male suffi- 
ciently distinguished subintegra from rubicunda, but its separation 
from the next subspecies, puberula is not so easy. F. subintegra is 
the common form of sanguinea in the Eastern States and Canada at 
low elevations and in warm situations. I have shown that its queens 
establish their colonies in the same manner as the queens of rubecunda. 
11. F. SANGUINEA SUBINTEGRA var. GILVESCENS, var. nov. 
WorkKErR. Length 4.5-5 mm. 
Differing from the typical subintegra in the following characters :— 
The anterior border of the clypeus is so feebly notched as to appear 
merely somewhat truncated in the middle; the erect hairs are very 
short and sparse on the gaster, almost lacking on the thorax, sparse 
but somewhat longer on the head, absent on the gula. Color yellow, 
gaster, head, and antennae tinged with brownish, in more immature 
specimens the head and antennae are yellow and the gaster is only a 
little darker than the thorax.
