Aranea Albini Scop. (Bnt. cam., p. 396), which Walckenaer 

 refers to this species (Ins. Apt., II, p. 241), seems to me hardly to 

 belong to it; at all events the description is too imperfect to admit 

 of any certainty: it applies equally well to L. triangularis (Clerck), 

 L. hortensis Sund., and others. An equally uncertain synonym, also 

 accepted by Walckenaer, is L. Walokenaeria Eisso ')• A person who 

 is acquainted with the character of Eisso's descriptions, does not feel 

 sure even that that spider is a LJnyphia at all, and not e. g. a 

 llcomisus or a Lycosa : according to Kisso in fact Argiope Brtinnichii 

 (Scop.) or Epeira fasciata Walck., and Argiope lobata (Pall.) or Ep. 

 serieea Walck., belong to the genus Segestria! I have therefore, in 

 company with Grube, Westring and others, retained the specific 

 name marginata (given almost contemporaneously by C. Koch and 

 Eeuss), which is the first by which the species before us has been 

 recognizably described, if we except Clerck's designation triangularis, 

 which name however, as we have above (p. 46, sub. Lin. triangu- 

 laris Westr.) shown, belongs to Lin. montana Walck., C. Koch, 

 Blackw. etc., with which L. marginata was by Clerck confounded. 

 Blackwall's L. marginata does not belong to this species , but is = 

 L. montana (Clerck) Westr. (See that spec. p. 44).

A careful comparison of L. thoracica Eeuss , Westr. with Black- 

 wall's description of L. eaitta, has clearly shown us, that these two 

 species are identical, as also Blackwall appears to have suspected. — 

 C. Koch erroneously takes up L. thoracica among the synonyms of 

 his Meta cellulana (Die Arachn., VIII, p. 123). Koch was unacquaint- 

 ed with this species, as was also Walckenaer, who (Ins. Apt., IV, 



1) Eisso's description of L. WalcJcenaeria is as follows: r Corselet arrondi, 

 verdatre , entoure sur les bords d'une ligne blanchatre ; abdomen vert , raye de plu- 

 sieurs rangees de points blancs en dessus, d'un blanc verdatre sur les bords et 

 sous le ventre. On voit qu'elle differt de la Linyphie triangulaire des auteurs.
