THERIDIID^E 



The members of this family have eight eyes, situated very much like those of the Argio- 

 pidit ; but the mandibles are usually weak, the maxillae are inclined over the labium, and the 

 posterior legs have a comb of stiff curved spines beneath the tarsi. The web consists of a 

 tangle of crossing lines, and the spider often constructs a tent-like retreat wherein the egg-sac 

 is hung up. The tarsal claws are three in number.

 and three tarsal claws. The species of Era construct a small brown pear-shaped or cylindrical 

 egg-cocoon suspended on a fine silken stalk.

DICTYNID^E 



The spiders belonging to this family possess three tarsal claws, and the eyes, eight in 

 number, situated in two transverse rows, the laterals being in contact. The cribellum (or 

 extra pair of spinning organs) and the calamistrum (a row of curving bristles on the protarsi of 

 the fourth pair of legs) are present in all members of the family. They construct a tubular 

 retreat with an outer sheet of webbing, which is covered with a flocculent silk made with the 

 calamistrum from threads furnished by the cribellum.
