74 ON NEW AND RARE BRITISH ARACHNIDS. 



Fam. THERIDIIDJE. 



Theridion salvum, sp.n., pi. A, figg. 8, 9. 



An adult male, taken at Warmwell by the Rev. 

 R. J. Pickard-Cambridge on iron railings in June, 1911. 

 It is nearly allied to Theridion denticulatum, Walck, but 

 may be easily distinguished by the structure of the 

 palpal organs. Sec pi. A, fig. 10. Bosenberg describes 

 and figures (" Die spinnen Deutschlands, pi. ix., fig. 

 124, p. 101) the male palpi of a spider he calls 

 Theridium pinastri, L. Koch, bearing some resemblance 

 in the palpi to the present species, but the spider he 

 represents is I think certainly not T. pinastri ; at any 

 rate it is quite different from types of Theridium 

 pinastri sent to me some years ago by Dr. L. Koch 

 himself ; it is also different in the palpi, and in other 

 respects from the spider now described ; and even if 

 it were the same, it would need re-naming, Bosenberg's 

 spider not being T. pinastri. Bosenberg also, I.e. supra 

 describes and figures another allied species (Theridion 

 braccatum L Koch a Tyrolese spider) . I have not seen a 

 type of this species, which, though allied to the present, 

 is also, I believe, distinct. (For description of T. salvum, 

 vide postea, p. 88.). 



Laseola prona, Menge. 



Euryopis prona, Menge-Cambr., Spider Dors., 

 p. 481, and Proc. Dors. F. Club, Vol. XIV., 

 p. 151, 1893. 

 Laseola jucunda, Cambr., Proc. Dors. F. Club, 



XXIX., p. 170. 



Both sexes received from Dr. A. R. Jackson, June 

 1911, and found in Dorsetshire. A careful comparison 

 of these with the type of L. prona, Menge-Cambr., 

 proves the identity of this spider with Laseola jucunda, 

 Cambr.
