ON NEW AND RARE BRITISH ARACHNIDS. 73 



Fam. DICTYNIDJE. 



Protadia patula, Sim., pi. A, figg. la, 2a, 3a, 4a, 5a, 6, 7. 



Lethia patula, Camb. Spid. Dors., p. 470. 



Dictyna patula, Sim., Arachn. de France, I., 



p. 197. 



Both sexes, adult, have been sent to me, in June, 1911, 

 by Dr. A. R. Jackson, by whom they were found at 

 Queensberry Ferry, on the river Dee. Until now the 

 female only of this species has been known ; examples of 

 this sex have been received from some other localities, 

 as well as from Sussex, where the first known British 

 specimens occurred. The male closely resembles the 

 female in colours and markings. For a fuller description 

 see postea (p. 85). 



Titanoeca quadriguttata, Hahn, pi. A, figg. 1, 2, 3, 4, 5. 



Titanoeca quadriguttata, Hahn, Simon, Arachn. 



de France, torn I., p. 215. 



An immature male of this spider was sent to me from 

 near Plymouth by Mr. J. H. Keys in 1911. The genus is 

 allied to Amaurobius, C. L. Koch, as well as to Dictyna, 

 Sund. The example recorded has been examined by 

 Mons. Simon, and, though not adult, is considered by him 

 to belong to this species (quadriguttata, Hahn.). I may 

 remark that Mons. Simon, in his latest work, includes 

 Titanoeca, Thor., as generically the same as Amaurobius, 

 C. L. Koch. At present I have thought it best to keep 

 them apart. (For a description of this spider vide p. 87, 

 postea). 



Hahnia Candida, Simon. 



Hahnia Candida, Simon-Cambr.Spid.Dors.,p.7l. 



Adults of both sexes were met with by Dr. Jackson in 



the Island of Portland in September, 1911. This is the 



first record of its occurrence since it was found in the 



same locality by myself many years ago.
