52 THE SPIDERS OF EPPING FOREST. 



Eyes arranged almost in a circle, the anteriors very close 

 together. Tarsal claws 2 or 3. Cephalo-thorax brownish 

 or blackish ,. ... .. .. Havpactes 



Genus DYSDERA, Latreille. 



Spiders of moderate size, fabricating a silken, tubular retreat,, 

 in which the eggs are laid, apparently not protected by an ovisac. 

 The females of the various species are extremely difficult to 

 distinguish one from another. 



Dysdera crocota, C. L. Koch. Theydon Bois. A male 

 and some females, the latter probably of this species, found 

 beneath stones. 



One other species, D. camhvidgii, Thor. is found in Britain. 



Gcuiis HARPACTES, Tempi. 



Spiders of elongate slender build, especially the males. 

 Habits generally similar to Dysdera. 



Harpactes hombergii, Scop. This species is rather 

 common and widely distributed in Epping Forest, and may 

 usually be found in the summer amongst dead leaves, and 

 during the winter months beneath loose bark. 



Gemis SEGESTRIA, Latreille. 



Spiders of moderate size with the thorax brownish or blackish 

 and the abdomen with a distinct pattern, consisting chiefly of a 

 longitudinal series of large blackish patches upon a paler ground. 

 These spiders live in tubes which are usually constructed 

 beneath loose bark. 



Segestria senoculata Linn. Widely distributed in the 

 Forest, and usually common under the loose bark of hornbeams, 

 etc. 



Two other species of Segestria are found in Britain, S. 

 havavica, C. L. Koch, and 5. floventina, Ross., but both are very 

 rare. 



Family OONOPIDAE. 

 [Dysderidae Cambr. List, ad partem.] 

 Cephalo-thorax of a short oval form and always more or less constricted in 

 front, its greatest convexity is usually rather near its posterior mai-gin, the slope 

 being there somewhat abrupt ; longitudinal stria obsolete or nearly so. Eyes 6, 

 homogeneous, of the nocturnal type, large, almost equal, very closely grouped. 

 Ocular area occupying almost the whole width of the caput. Falces conical, 

 rather weak, considerably attenuated towards their extremities : fang slender : 

 fang-^rroove without denticulations. Lahimn free. Steiniun very large and -well 

 developed, convex, of broad-oval form, very wide and obtuse behind. Maxillae
