Keyserling, in vol. ii. of his Spinnen Amerikas, treats on a portion of 
this family, describing and figuring Theridium 63, Centropelma 1, Gau- 
celmus 1, Achcea 9, Steatoda 3, Teutana 3, Lithyphantes 10, Lathrodectus 
2, Chrysso 4, Hildbolda 1, Faiditus 2, Thymoites 1, Thwaitesia 2,

Coleosomci 1, Formic,inoides 2, Bellincla 1, Theridiosoma , 4 spp. The 
European Theridium tepidariorum, Steatoda bipunctata, Teutana tri- 
angulosa , Uthyphantes corollatus, Episinus truncatus (?) also occur in 
America. 
Simon, in his Arachnides de France, v. pts. 2 & 3, p. 181 seg., con¬ 
tinues this family, treating of his 6th section, Erigonini , to which belong 
6 groups : Enoplognathini (gen. Enoplognatha , Pedanostethus = Ctenium , 
preocc.), Linyph(i)ini (gen. Tapinopa, Bolyphantes , Drapetisca, Linyphia , 
Leptyphantes , Bathyphantes, Tmeticus , Microneta , and several new ones), 
Lophocarenini, Walckenaerini, Cinetini, Masonini; the four latter of 
which are placed by Bertkau in the family Micryphantidce (vide supra'). 
The males of the Enoplognathini are stridulating, the stridulating appa¬ 
ratus in Pedanostethus being in a rudimentary condition.
