CLASS ARACHNIDA. 
little above their base, and terminate in the form of a pallet 
or spatula. The tarsi of the last three pair of feet terminate 
in a single claw. The first articulation of the two posterior 
ones has a range of little hairs. 
These weavers, as well as the species of the following sub- 
genus, have the body elongated, and almost cylindrical. 
Placed at the centre of their web, they carry forward, and in 
a straight line, the four anterior feet, and extend the last two 
in an opposite direction ; those of the third pair are directed 
laterally. 
These arachnides form webs similar to those of the other 
orbiteles, but more loose, and horizontal ; they completely en- 
velope, in less than three minutes, the body of a small coleop- 
terous insect, which is caught in their net. Their cocoon is 
narrow, elongated, angular on the edges, and suspended ver- 
tically, by one of its ends, to a net- work ; the other extremity 
is as it w ere forked, or terminated by two prolonged angles, 
one of which is shorter, and obtuse. Each side has two acute 
angles. 
I am indebted for these interesting observations to my friend 
M. LeonDufour.

Whose eyes are situated, four by four, on tw’O lines almost 
parallel, and separated by intervals nearly equal, and which 
have jaws long, and narrow", and widened only at their supe- 
rior extremity. Their forceps are also very long, particularly 
in the males. The web is vertical.
