ON BRITISH ARACHNIDA. 51 



Fam. AGELENIDJE. 



Cryphoeca incisa, Cambr. 



Two adult females, found in nests of Formica fusca, 

 were kindly sent to me in May, 1909, by Mr. H. Donis- 

 thorpe, from Bradgate Park, Leicestershire. 



Cieurina einerea, Panz. 



Adult and immature females found in nests of Lasius 

 fuliginosus, Darenth Wood, in September, 1909, were 

 sent to me by Mr. H. Donisthorpe. 



Tegenaria Derhamii, Scop. 



Dr. Oliver, of Bradford, Yorkshire, tells me that 

 a female of this species (just dead) had lived under his 

 care seven years in confinement ; and another example 

 five years. These are supposed by Dr. Oliver to have 

 furnished instances of " Parthenogenesis," but the 

 evidence did not appear to me conclusive on the point. 



Fam. THERIDIIDJE. 



Theridion aulicum, Luc. 



Adults of both sexes of this rare and local spider 

 were found in June, 1909, at the Sandbanks, near Poole, 

 and also Morden Park, Bloxworth, by Dr. A. R. Jackson, 

 and my son, Alfred E. LI. Pickard-Cambridge. 



Leptyphantes patens, Cambr. 



The spider recorded (Proc. Dors. F. Club, Vol. XXVIII., 

 p. 140, pi. A, figs. 20, 21), as the female of this species 

 appears to be most probably that of Leptyphantes pallidus, 

 Cambr.
