A HISTORY OF CORNWALL 



reports that the spider does not leave this retreat in 

 search of prey, but waits in the slack portion of the 

 tube lying outside the burrow until some insect sets 

 foot upon this silken, purse-like structure. Instantly 

 the fangs of the spider's mandibles are stuck through 

 the walls of the tube, the insect seized and dropped 

 into the burrow through a rent in the silk, which is 

 afterwards mended from within. The male is smaller, 



almost black, and may sometimes be found moving 

 slowly about in the sunshine in the neighbourhood 

 of the colony. The species occurs all along the 

 coast from Hastings to the Land's End, and in 

 various localities inland. On the Cornish coast I have 

 found it on the downs close to the edge of the cliffs 

 under stones. The spider has also been recorded under 

 the names A. sulzerl and A. piceus by English authors. 



DYSDERIDAE 



Spiders with six eyes and two pairs of stigmatic 

 openings, situated close together on the genital rima ; 

 the anterior pair communicating with lung books, 

 the posterior with tracheal tubes. Tarsal claws, 

 two in Dysdera, three in Harfactes and Segestria. 



2. Dysdera cambridgii, Thorell. 



Saltash (G. C. B.). 



Not uncommon under stones and bark of trees, 

 where it lurks within a tubular retreat. The spider 

 is easily recognizable by its elongate form, orange 

 legs, dark mahogany carapace, and pale clay yellow 

 abdomen. The palpal bulb of the male has no 

 cross-piece at the apex. The spider is also known 

 as D. erythrina, Blackwall. 



3. Dysdera crocota, C. L. Koch. 



Gerrans Bay. 



Larger than the last species, with a deep orange- 

 pink carapace, orange legs, and abdomen with a 

 delicate rose-pink flush. The palpal bulb of the male 



has a cross-piece at the apex. This spider is also 

 known as D. rubicunda, Blackwall. 



4. Harfactes homberglt, Scopoli. 



Whitsand Bay (G. C. B.). 



Rare under bark of trees, and recognizable by its 

 linear ant-like form, black carapace, and pale clay 

 yellow abdomen and three tarsal claws. 



5. Segestria senoculata, Linnaeus. 



Polperro. 



Not common ; under bark of trees, in the crevices 

 of loose stone walls and amongst detached rocks. 

 Recognized by its linear form and black diamond- 

 shaped blotches on the dorsal surface of the abdomen. 



6. Omops pulcher, Templeton. 



Liskeard. 



Rare ; a very small linear brick-red spider, often 

 found on the walls of bedrooms, as well as beneath 

 stones. 



DRASSIDAE 



Spiders with eight eyes, situated in two transverse 

 rows. The tracheal openings lie just in front of the 

 spinners. The tarsal claws are two in number, the 

 anterior pair of spinners are set wide apart at the 

 base, and the maxillae are more or less impressed 

 across the middle. 



7. Drasiodes lapidosut, Walckenaer. 



Polperro ; Looe ; Liskeard. 



Very common under stones. Also known as Drastus 

 lapidicolens. 



8. Scotophaeus blackwallii, Thorell. 



Liskeard. 



A dark elongate mouse-grey spider, often found 

 wandering about the walls of dwelling- and out-houses 

 at night. Known also as Drassus serictus, Blackwall. 



9. Prostheslma petiverii, Scopoli. 



Downderry Cliffs (G. C. B.). 



10. Prosthestma pedestris, C. L. Koch. 



Whitsand Bay ; Downderry Cliffs (G. C. B.) ; 

 Polperro. 



1 1 . Micaria puRcarla, Sundevall. 



Mawnan, Polperro. 



A brilliant little spider with iridescent scales on its 

 body. Not uncommon running about in the hot 

 sunshine. Known also as Drassus nltens and Drassus 

 micans, Blackwall. 



12. M icaria scintillans, O. P.-Cambridge. 



Downderry Cliffs (G. C. B.). 



A much rarer and rather larger species found be- 

 neath stones or running about in the hot sunshine. 

 A male and two females were taken by Mr. Bignell 

 in May. 



13. Micarlosoma festtvum, C. L. Koch. 



Liskeard. 



Very similar in general appearance to those of 

 the last genus, but smaller and more ant-like. 

 Known also as Phrunllthus festivus and Drassus propin- 

 guus, Blackwall. 



Spiders with eight eyes, situated in two transverse 

 rows. The tracheal openings lie immediately in front 

 of the spinners. The tarsal claws are two in num- 

 ber, but the anterior pair of spinners are set close 

 together at the base ; the maxillae are convex and 

 not impressed across the middle. 



CLUBIONIDAE 



1 4. Lycodia sptnimana, Sundevall. 

 Gerrans Bay. 



Known also as Zora and Hecaerge tpinimana or 

 maculata.
