Linyphia elatlirata Sund. (Neriene mar- 

 ginata Bl. ) 



Length. Male 3.5 mm., female 4 mm. 



Cephalo- thorax blackish-brown. The anterior por- 

 tion of the abdomen is usually occupied by two large 

 whitish spots. A very common species, almost in- 

 variably found amongst low herbage and debris. 



Linyphia furtiva Cb. 

 Length. Male 4 mm., female larger. 

 Closely allied to L. clathrata Sund. It may be dis- 

 tinguished by the general colouring being more 



Stemonyphantes lineata. Female ; palpal organs 

 and vulva. 



blackish, and by the profile line of the cephalo-thorax 

 being almost absolutely straight. A rare spider, 

 found amongst heather. I have takenit at Oxshott, 

 in Surrey. 



GENUS STEMONYPHANTES Menge. 



Closely allied to Linyphia, but the anterior tarsi 

 are somewhat longer than half the metatarsi. 



Stemonyphantes lineata Linn. {Lhiyphia 

 bucculenta in "Spiders of Dorset"; Neriene iri- 

 lineata Bl. ) 



Length. Male 5.5 mm., female considerably 

 larger. 



The male palpal organs are excessively large and 

 of a reddish-brown colour. This species is figured. 

 It is very common. 



GENUS BOLYPHANTES MENGE. 



Anterior tarsi at least two-thirds the length of the 

 metatarsi. 



Bolyphantes alticeps Sund. 



Length. Male 4 mm., female larger. 



The caput is conically elevated, forming a point 

 between the eyes. A rare species, found in the 

 North of England. 



Bolyphantes luteolus Bl. {Linyphia alticeps 

 Bl.) 



Length. Male 3.5 mm., female larger. 



Very similar to B. alticeps Sund., but the caput, 

 although considerably raised, is not drawn out into a 

 conical point between the eyes. A common species 

 in the North of England. 



Bolyphantes bueeulentus Ok. [Linyphia 

 frenata Wid.) 



Length. Male 3 mm., female considerably larger. 



The caput of the male is somewhat elevated and 

 rounded at its summit. It may be distinguished 

 from its allies by the anterior row of eyes being con- 

 siderably curved. A rare species. 



Drapetisca socialis. Female ; palpal organs and vulva. 



Bolyphantes expuncta Cb. 



Length. Male 3 mm., female 3 mm. 



Cephalo-thorax yellow, with blackish margins. 

 Behind the eyes is a wedge-shaped dark mark, and 

 there are some blackish converging lines. Abdomen 

 brownish - yellow, with numerous yellowish - white 

 spots. A very rare species. 



GENUS TAPINOPA WESTR. 



This genus may be distinguished from its allies by 

 the clypeus being very low, much narrower in fact 

 than the ocular area.
