700 Prof. A. Forel's Descriptions of some Ants, etc. 



N.B. — Tlie description of ^f//rm. sahddi, var. lohifrons, 

 Pergande, of Alaska, is so insufficient that it is not possible 

 to ascertain this form. But the scapus of the var. frigida 

 of brevinodis is very gradually curved at the base (more 

 broken in M. salndcti).
