acute ; thoracic spines slender. Color brownish yellow ; borders of clypeus and

 or blackish.

2. A. (T.) septentrionalis var. vertebrata, new var. 



Worker. — Length 2.5-3.3 n\m. 



Differing from the typical form in its smaller size, coloration and sculpture. 

 The dark spots and bands on the head, gaster and postpetiole are broader and 

 more extensive, and the thorax is infuscated in the middorsal line. In some 

 specimens the pleur£e and venter are also brownish. The surface of the body 

 is more opaque and the spines and tubercles are even smaller than in the 

 typical form. 



Female. — Differing from the female of the typical form in having the pro- 

 notum, mesonotum and petiole blotched with brown. Body opaque ; sculpture 

 as in the typical form. 



Described from nimierous workers and two dealated females taken 

 by myself from a single colony at Lakehurst, N. J. 



3. A. (T.) septentrionalis obscurior Wheeler, 



Worker. — Length 3—3.5 mm. 



Differing from the typical form in color, sculpture, pilosity and the shape 

 of the gaster. The body is deep ferruginous, with slightly paler legs, the front 

 and vertex and a visually very indistinct dorsal band or spot on the gaster, 

 brownish. There is no dark spot on the postpetiole. The body is opaque and 

 distinctly granular. The tubercles are all larger and more prominent and' the 

 spines on that account seem to be more robust and blunter, though not longer 

 than in the typical form. The hooked hairs covering the body and appendages 

 are coarser though no longer than in the type. The gaster is less globose, being 

 flatter above and with straighter, subparallel and distinctly ridged sides. 



Female. — Length 3.8—4 mm. 



Resembling the worker, but the sculpture is coarser. The dark spot on the 

 head is deeper and restricted to the occllar region ; the band on the gaster is 

 also more distinct.
