and ii. with 2—2—2—2 spines; protarsi i. and 1. with

Some of the genera, Stephanopoides, Hpicadus, Metatobias, Cenypha, and Sidyma, 
which enter into this Table have as yet no representative species from Central America. 
They find a place on account of their very close relationship with the others, and 
because representatives are almost certain to be found sooner or later. 
In identifying these genera and differentiating them, general characters will be found 
more reliable, perhaps, than those drawn from the relative position of the eyes or, 
indeed, any single character abstracted from the rest. The form of the abdomen, for 
instance, will give a good clue to the generic group to which any spider belongs. But 
the whole group really needs to be taken in hand and thoroughly diagnosed com- 
paratively in connection with examples from all parts of the world.
