374 Dr. A. Forel, Formicides 
Genre CypHomyrMEx, Mayr. 
Cyphomyrmex rimosus, Spinola. 
(=Cyphomyrmex deformis, Sm., nec. Mayr, F. novoer.). 
(Noi b0:0/a 507). (3 Sig. 
(= Cyphomyrmex steinheili, Forel, Kt. myrm., 1884). 
(50). Common, in open or shady ground. Communities 
of four or five to twenty—rarely larger—to one hundred 
individuals. The formicarium is a simple cavity under 
a stone or stick, at the roots of grass, or occasionally in 
rotten wood. ‘The ants are very sluggish, hardly moving 
when disturbed. I have not found the workers in beating 
foliage, and judge that they are nocturnal, and probably 
terrestrial, in their habits. I have perhaps included 
more than one species under this number. ‘Those found 
in a nest are always of the same colour, or nearly so; 
and, though the colour may be due to age, it is singular 
that there should be no variation in a community. There 
seem also to be differences of size and form; but my 
object in separating the species is simply to get better 
notes on them, and of course the work is very roughly 
done. Ihave found these ants crawling, towards evening, 
on the floor of a dark outhouse. They move slowly.
