Sub-fam. I. PHILODROMINZE. 
The powerful development of the posterior extremities gives the spi- 
ders of this sub-family that quickness and lightness of motion in which 
they so remarkably excell the Zhomisinæ. — The claws are long and slender, 
generally straight or somewhat sinuated (i. e. slightly curved in the form of 
an ~) the greater part of their length, with only the extremity bent down 
to a hook. The claw-tufts vary in length and density, but are always pre- 
sent. — We assign the genus Selenops to this sub-family; by SIMON it is 
referred to the Thomisinæ, because the eyes in that genus are of different 
sizes, which he considers as one of the features by which the Thomi- 
sine are distinguished from the Philodrominæ. This is however no reliable 
characteristic, and indeed Simon himself, in his description of the genus 
Thomisus, says: "yeux égaux" 1).

1) The exotie genus Delena WALCK. also we refer to the Philodrominæ, and 
not, as is done by SIMON, to the Thomisinæ. Its hinder pairs of legs are indeed 
not ineonsiderably shorter than the fore legs, but they are about equal to them in 
strength; and by the presence of strong claw-brushes, by the form of the claws 
themselves, and the powerfully developed scopulæ under the metatarsi and tarsi, as 
well as by its general appearance, Delena betrays a close affinity to Heteropoda.
