PULMONARLE. 295 



CLUBIONA, Lat. 



This submenus is only distinguished from the following one by the 

 nearly equal length of the exterior fusi, and by the straightness of the 

 line formed by the four anterior eyes. The Clubionae construct 

 silky tubes under stones, in chinks of walls, or between leaves. Their 

 cocoons are globular *. 



ARANEA. 



The true Aranea, which we at first designated by the generic ap- 

 pellation of Trgcnaria, retained by Walckenaer, and to which we add 

 his Angeleua- and Nyssi, have their two superior fusi much longer 

 than the others, and their four anterior eyes arranged in a line pos- 

 teriorly arcuated or forming a curve. 



They construct in our houses, in the angles of walls, on plants, 

 hedges, along the roads, in the earth, and under stones, a large and 

 nearly horizontal web, at the upper part of which is a tube where 

 they remain motionless f. 



Then follow the Naiades of Walckenaer, or our aquatic Tubitela*, 

 which form the 



ARGYRONETA, Lat. 



The jaws are inclined on the ligula, which is triangular. Th 

 two eyes of each lateral extremity of the ocular group are closely 

 approximated and placed on a particular eminence ; the four others 

 form a quadrilateral. 



Argyroneta aqualica ; Aranea aquatica, L., Geoff., Deg. 



Blackish brown, the abdomen darker ; silky ; four depressed 



points on the back. It is found on the stagnant waters of Europe, 



where it swims with the abdomen enclosed in a bubble of air; 



it forms an oval cell, filled with air, and lined with silk, from 



which various threads extend to the surrounding plants. Here 



it lies in wait for its prey, deposits its cocoons, which it carefully 



watches, and encloses itself to pass the winter. 



In the second section of the sedentary and rectigrade spiders, that 



of the INEQUITEL^E, the external papillae are nearly conical, project 



but little, are convergent, and form a rosette ; the legs are very slen- 



<1 r. The jaws incline over the lip, and become narrower at their 



superior extremity, or at least do not sensibly widen. 



Most of them have the first pair of legs longest, and then the 

 fourth. The abdomen is more voluminous, softer, and more coloured 

 than in the i>irrediii tribes. Their webs form an irregular net 

 composed of threads which cross each other in every direction, and 

 on several planes. They lie in wait for their prey, display much
