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 sanguine a 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 rubicunda. 



11. F. SAN GUINEA SUBINTEGRA Var. GILVESCENS, var. nOV. 



Worker. 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.
