quite evident from consulting Emery's table of the North- 
American species of the genus (95, pp. 317,318). 
The above very incomplete account of the female is drawn 
from memory, as the single specimen escaped from the nest 
before it could be described. 
Some of the workers, especially those which approached the 
queen in size, possessed minute ocelli. This is shown by the 
following measurements of the four workers stil in my 
collection : 
I. Length 2.5 mm. No ocelli. 
No. 2. Length 2.75 mm. No ocelli. 
3. Length 3 mm. Two ocelli. 
No. 4. Length 3.5 mm. Three ocelli. 
This fact is of some interest, as I shall endeavor to show in 
the sequel. 
On the morning of August 25 the ants were transferred 
to an extemporized Lubbock nest. This consisted of a board 
surrounded by water, and a little fine, moist earth placed on 
the board and covered with a pane of glass. A census of the 
two species of ants gave the following : 
Myrmica: 6 deálated! queens; 7 males ; about 200 workers; 
a few eggs; 23 larva, both young and old (but apparently no 
queen larva) ; 8 worker and male pupa. The latter hatched 
in the course of a few days. 
Leptothorax: 1 deálated queen; 4 recently hatched males ; 
14 workers; 2 adult larvae, which soon became male pupa. 
The earth with its occupants was dumped from the bag on to 
the pane of the Lubbock nest, and the ants, after the first 
flurry of excitement, began to seek refuge under the glass. 
As usual the larvze and pupa were at once conveyed to a place 
of safety. While this operation was going on, it was noticed 
that some of the Myrmica workers carried the Leptothorax 
larvze, and the Leptothorax workers reciprocated by occasionally 
1I feel compelled to coin this term for use in the sense of the German “ent 
fliigelt.” The term aféerous cannot be used without confusion, since some ants 
(Eciton, Dorylus, Leptogenys, Tomognathus) have truly apterous queens, wt 
=r queens of most species of Formicidæ have well-developed wings, up t° the 
time of their removal after the nuptual flight.
