A HISTORY OF DEVONSHIRE 



DRASSIDAE 



Spiders with eight eyes, situated in two transverse 

 rows. The tracheal openings are 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. Drassodes lapidosus, Walckenaer. 



Mount Batten, Plymouth (G. C. B.) ; Salcombe 

 (T. R. R. S.). 



CLUBIONIDAE 



Very common under stones. Also known as Drassut 

 lapUkokns. 



8. Prosthesima petiverii, Scopoli. 

 Salcombe (T. R. R. S.). 



9. Prosthesima pedestris, C. L. 

 (O, P.-C). 



Koch. 



Spiders with eight eyes, situated in two transverse 

 rows. The tracheal openings are immediately in front 

 of the spinners. The tarsal claws are two in number, 

 but the anterior pair of spinners are set close together 

 at the base ; the maxillae are convex and not impressed 

 across the middle. 



10. Clubiona terrestris, Westring. 

 Bickleigh (G. C. B.). 



Not uncommon in the summer time, when it may 

 be found wandering about at night on the walls of out- 

 houses, palings, etc. Known also as C. amarontha, 

 Blackwall. 



11. Ckiionareckja,0.'P.~CimhTidge. 



Beer Ferris (G. C. B.). 

 A rarer species than the last ; usually beaten from 

 foliage and bushes in the summer time. 



12. Clubiona brevipes, Blackwall. 



Ivybridge ; Langstone (G. C. B.) ; Ilfracombe 

 (T. R. R. S.). 

 Not uncommon amongst foliage in the summer time. 



13. Clubiona compta, C. L. Koch. 



Langstone ; Bickleigh ; Horrabridge (G. C. B.). 



A very small species, whose abdomen is striped 



diagonally on each side, similarly to that of C. corticalis. 



Not uncommon amongst the foliage of bushes and 



shrubs in the summer time. 



14. Micaria pttlicaria, Sundevall. 



Salcombe (T. R. R. 8.). 

 A brilliant little spider with iridescent scales on its 

 body. Not uncommon, running about in the hot 

 sunshine. Known also as Drassus nitens and D. micons, 

 Blackwall. 



ANYPHAENIDAE 



15. Anyphaena accentuota, Walckenaer. 

 Ivybridge (G. C. B.) 



Often common on the foliage of oak and other trees. 

 This spider is remarkable for the position of the spira- 



cular opening, which is situated in the middle of the 

 ventral surface of the abdomen between the genital 

 rima and the spinners, and not, as in the last family 

 immediately in front of the spinners. Known also 

 under Clubiona, 



THOMISIDAE 



Spiders with eight eyes, situated in two transverse 

 rows, two tarsal claws, and anterior spinners close to- 

 gether at the base. Maxillae not impressed. The 

 crab-like shape and side-long movements of the spiders 

 are their chief characteristics, enabling them to be 

 easily distinguished, as a rule, from the more elongate 

 Drassidae and Clubionidae. 



1 6. Philodromus margaritatus, Clerck. 



Bickleigh (G. C. B.). 

 This magnificient species, by far the largest of the 

 genus found in Great Britain, is not uncommon in 

 many parts of England. Its mottled white, black 

 and grey hues blend admirably with the lichen- 

 covered trees which they frequent, and unless the 

 spiders move it is almost impossible to see them. 

 The beautiful variety P. tigrinus, De Geer, also named 

 P.jejunus, C. L. Koch, almost pure white, with distinct 

 spots and blotches, is also not uncommon. 



1 7. Philodromus dispar, Walckenaer. 



Bickleigh (G. C. B.) ; Salcombe (T. R. R. S.). 

 This species with its shiny black abdomen is not 

 uncommon in the summer time amongst foliage, and 

 can sometimes be observed crouching flat upon 

 palings. It is very swift in its movements. 



18. Philodromus aureolus, C\e.xc\i. 



Salcombe (T. R. R. S.). 

 A very abundant species with usually a dull red 

 abdomen, with yellowish central pattern. It fre- 

 quents the foliage of trees of all kinds, and especi- 

 ally in the immature condition will outnumber all 

 other species which fall into the umbrella beneath 

 the beating-stick. 



1 9. Philodromus caespiticoRs, Walckenaer. 



Exeter (O. P.-C). 

 The species is possibly only a variety of the last 

 named, and frequents similar situations. Known 

 also as P. cespiticolens, Blackwall. 



20. Philodromus fallax, Sundevall. 



North Devon (T. R. R. S.) 



This beautiful spider lives amongst the sand-hills 



and runs swiftly, squatting when at rest quite flat 



on the sand, which it so exactly resembles in tint 



as to be impossible to detect from its surroundings. 



2 1 . Xysticus cristatus, Clerck. 



(O. P.-C.) 

 This is by far the commonest of the 'crab- 

 spiders,' and is found abundantly on foliage or
