stumble against him ; once found, they lay hold of the 
clothes, or whatever they can get at, and cling so firmly 
that I have sometimes found them still attached after 
an hour or more. I have never found the males and 
females in a colony; probably they keep to the inner 
passages of the nest.

1. Prenolepis longicornis, Latr., 3 9 ¢. (No. 17). 
(17). A common species about houses and open places, 
not far from sea-level. The formicarium is subterranean 
and extensive, with passages half an inch in diameter to 
the open ground above, or under stones. The colony 
contains many hundreds or thousands of individuals. 
The winged forms and larve are often exposed by turning 
over stones, but the ants carry them rapidly to lower 
parts of the nest, six inches or more below the surface. 
The workers are very active and bold; when foraging 
they run jerkily from side to side. They are especially 
fond of dead animal matter. When working over insects 
I have often been amused, as well as annoyed, to observe 
the boldness of these little foragers. If an ant discovers 
one of the insects she seizes it at once, and tries to drag 
it from the table. If I brush her off, she dodges around 
and behind the precious morsel, and seizes it again. 
Driven quite away, she runs to some shelter, but returns 
almost immediately, trying to drag the insect even from 
my fingers; and nothing short of mutilation or death 
will effectually stop her. One ant will drag away a load 
ten times as large and heavy as herself, always walking
