This species, which is distinguished by the patellar joint of 

 the male's palpus being drawn out into a sharp angle, is not de- 

 scribed in Blackwall's work. Westring was acquainted only with 

 the male: I have also a (dried) specimen of the female , in which the 

 abdomen, as in the male, is of a uniform dark brown colour. The 

 vulva has the form of a large, reddish-brown, transversal area 

 rounded in front and more truncated behind, limited by an elevated 

 border, and bisected by a longitudinal, almost uniformly broad sep- 

 tum, which reaches with its rounded and deflected apex a little be- 

 yond the posterior limit of the area. The mandibles and the spines 

 on the legs are somewhat shorter than in cf- 



(Pag. 129.) 22. L. index [= Linyphia index Thor. 1856]. 



Syn.: 1856. Linyphia index Thor., Eec. crit. aran., p. 107. 



Westring's suspicion, that L. index may perhaps be identical 

 with Bolyphantes stramineus C. Koch (Die Arachn., VIII, p. 71, fig. 

 643) I cannot share, especially as not even the colour is the same 

 in the two species. L. index has dark lateral borders to the cepha- 

 lothorax, which appear to be wanting in B. stramineus. — Menge's 

 B. stramineus, among the synonyms of which L. index has been 

 erroneously included, is the same as L. af finis Westr. or luteola 

 Blackw. On Bol. stramineus Koch, L. index and L. luteola, see more 

 above, p. 62, under the head of L. alticeps Westr. 



A cT-specimen of L. index from Bnare (Lappland) has been 

 sent me by v. Nordmann. Dr. L. Koch has sent me both cf and ? 

 (from Niirnberg) of this species, which as to the colour much re- 

 sembles L. luteola or affinis, but may easily be recognized by the 

 different armature of the metatarsi etc. In L. luteola the vulva 

 shows a small obtuse process behind ; in L. index its anterior margin 

 appears to be drawn out into a much longer process directed back- 

 wards and curved upwards (toward the belly).
