ofttimes several of the other joints are divided into smaller 
portions by what are termed false articulations. Each tarsus 
is terminated by one or two claws. 
The habits of the Phalangida are rather simple. With our 
common forms the length of life is but one year. The eggs are 
laid in the ground, or in crevices of wet or decaying wood, 
during the summer or fall; the young hatch in late fall or 
early spring. At birth they have the general appearance of

species having short palpi when adult have long palpi when 
young. In several of our species the young have the patella 
of the palpus with a long branch, whereas it is absent or 
nearly so in the adults. 
They spin no web and make no retreat of any kind. They 
usually move slowly, but a few can run rapidly. Some species

on living insects, but sometimes on decaying animal matter. 
They appear to have few enemies, but their long legs or hard
