HARPACTES HOMBERGII. 



Dysdera homberqii, Scop., Blackw., Spid., Great Brit, and 

 Irel., p. 371, pi. xxviii, fig. 268. 

 A common spider, in most localities, underneath, the loose and 

 decaying bark of trees, under stones, and among old faggots 

 and firewood. I have also found it not unfroquently among 

 moss and grass, and at the roots of heather at Bloxworth. It is 

 of a slender and attenuated form ; its legs are yellowish brown, 

 annulated with red brown; the cephalo-thorax dark blackish 

 red-brown, and the abdomen of a dull brownish clay-colour, 

 paler just above the spinners. The length of the female is 

 about one-fourth of an inch, and the male is rather smaller and 

 slenderer. 



GENUS SEGESTRIA, Latr. 



The Genus Segestria may be distinguished from both Dysdera 

 and Harpactes by a totally different position of its six eyes; 

 theso are here placed in three groups : one pair (in a transverso 

 line) in the centre, and another pair (in a longitudinal line) on 

 oach sido, at a little distance from the central group. The 

 terminal tarsal claws are three in number. Legs, 1.2.4.3. Three 

 species are known as British, two only being found in Dorset- 

 shire. 



SEGESTRIA SENOCULATA, 



Seqestria senooulata, Linn. ; Blackw., Spid. Great Brit, and 

 Irel., p. 374, pi. xxviii., fig. 270. 



This fine spider is found under stones at Portland, and also 

 at Bloxworth, and in many other localities, under loose bark, 

 enclosed in a thin tubular web. I have also found it snugly 

 domiciled between the hinder part of a gate and the post, 

 when the gate had not been opened for some little time. It 

 may easily be known by the back of the abdomen bearing a 

 resemblance in its markings to the back of an adder, being
