Epeirid^. 
Oiileut (Aran. Preuss.) admits the following 8 genera in this family : — 
Epeira, Singa, Miranda^ Atea, Zilla^ Meta^ and Tctragnatha. Tho 
total number of species described is only 23. 
Aranea lobata (Pallas). Thorell (GEfvers. Kongl. Vet.-Akad. Fbrh. 1867, 
pp. 591-690) discusses the synonymy of this species, which, from the citation 
by Pallas of a species from the Cape of Good Hope figured by Petiver, has 
been supposed to be extra-European. In his ‘ Naturg. merkw. Thiere, 9*® 
Sammlung,’ published in 1777, Pallas states that his A. lobata inhabits the 
south of Russia; and Thorell now identifies the species with sericea (Oliv.) 
belonging to the genus Argiope. The synonymy of Argiope lobata (Pall.) is 
given as follows by Thorell : = smicea (Oliv. &c.) = margaritacea (Risso)=«r- 
gentea {Qme\.) — dentata (Risso, N?i\o\i.)=prcelautus (Koch). 
L. Koch (Verh. zool.-bot. Ges. in Wien, xvii. p. 185) describes the mature 
female of Tetragnatha granulata (Walck.).
