414 CLASS ARACHNIDA. 



Utile 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 <;arry foi'ward, 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 were 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. Leon Dufour. 



VI. Walckenarins, Lat. Nearly five lines in length, of a 

 reddish yellow, covered with a silky down, forming on the 

 upper part of the abdomen two series of little bundles; some 

 rings, paler at the feet. Of the woods in the environs of 

 Bordeaux, and the other southern departments. 



Tetragnatha, Latr., 



Whose eyes are situated, four by four, on two 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.
