469 . Hentz's Descriptions of the 
Genus 'TEcENania.. Latr. Walck. 
Characters. Cheliceres moderately long ; maaxille parallel, 
rounded, very slightly inclined towards the lip ; lip short, 
rounded at tip; eyes eight, equal, in two rows, anterior one 
composed of four eyes in a straight line, posterior one 
longer, curved towards the base ; feet, fourth pair longest, 
then the first, the other two nearly equal. 
Habits. Araneides sedentary, making in obscure corners 
an horizontal web, at the upper part of which is a tubular 
habitation where the spider. remains motionless till some in- 
sect be entangled in the threads. 
Remarks. The distinction first proposed by Latreille 
between this and the Acetena of Walckenaer should be pre- 
served. The habits of the spiders differ considerably, and 
the position of the eyes is so different as to point out the 
necessity of a separation. I would have preserved the name 
pne to this division ; but confused ideas would arise from 
ributing to a Viligims the name, which, though legitimate, 
esa more properly to the whole family of spiders. 
These make webs of slender texture in dark places without 
the addition of the strong cross threads which AGELENA adds 
to the horizontal texture. It is only at night that d can be 
seen at work in the construction of their webs.
