Genus PACHYGNATHA (Pa-chyg'na-tha) 



The species of this genus are of moderate size, and in general 

 appearance resemble certain of the Theridiida} (Steatoda), the 

 abdomen being oval and rounded; but in details of structure they 

 are clearly allied to Tetragnatha. The cephalothorax is usually 

 yellow with an obscure border and median band; and the abdomen 

 is ornamented above with a re- 

 ticulated folium. The endites 

 are convergent and not dilated 

 at the distal end. (Fig. 420).

These spiders are found on the ground under stones, wood, 

 or leaves, and especially in damp places. 1 have also swept them 

 from aquatic plants over water in a lagoon. They are not known 

 to spin webs of any kind. 



The genus is represented in this country by several widely 

 distributed species, of which the following is the most common.
