224 LINYPHIIDiE. 
This spider, which occurs in autumn on the trunks of trees in woods at Oakland, M. 
Walckenaer has portrayed in his ‘ Hist. Nat. des Insect. Apt.’ pi. xxi, fig. f. 2 d, under 
the name of Theridion yonjie; but has prefixed to his description of it, tom. ii, p. 274, the 
appellation of linyphia bucculenta, conferred by Professor Sundevall on a very different 
species; namely, on that designated Linyphia reticulata, by M. Walckenaer (‘Yet. Acad. 
Handl.,’ 1831, p. 109). 
Both sexes of Linyphia socialis have been received from Mr. J. Hardy, who took them 
in Berwickshire.
