672 Formation of Colonies by Lasius fuliginosus, 
parison with their 66 than the queens of the rest of the 
genus, and have large heads and small bodies. It is clear 
that 29 with delayed fertility and such a small store of 
body fat could not possibly exist without assistance during 
the two years that must elapse between their impregna- 
tion and the appearance of the first $@ from their eggs. 
In short, this proves that queens of this species are unable 
to found colonies by themselves. 
Appended is a list of all the literature on the subject 
known to us.
