ON NEW AND RARE ARACHNIDS. 41 



Erigone Welchii, Jackson. PL A, figs. 25, 26, 27. 



Erigone Welchii, Jackson, " Irish Naturalist," 

 Feb., 1911, Vol. XX., pp. 28-31, pi. 6. 



Both sexes of this fine and very distinct species were 

 received for examination from Dr. A. K. Jackson in 1910. 

 They were found by Mr. R. Welch, of Belfast, in the 

 county of Donegal, Ireland. The form of the palpi will 

 distinguish the male at a glance from all the others of the 

 genus as yet known as British. In general colouring 

 and appearance, however, it nearly resembles several 

 others ; though perhaps its nearest ally is Erigone 

 psychrophila, Thor., a remarkable form found in the 

 Arctic regions, Nova Zembla, &c. E. Welchii is a fine 

 addition to the British and Irish list. 



Lophomma laudatum, Cambr. 



Among many other spiders obtained by W. A. 

 P.-C. near Barmouth, N. Wales, in September, 1910, 

 was a male of this species. 



Lophoearenum nemorale, Bl. 



Lophocarenum stramineum, Cambr., Proc. Dor. 

 N.H. and A.F. Club, Vol. XXVIII., p. 132, pi. B, 

 fig. 51-53, also Vol. XXX., p. 106, and Vol. 

 XXXI., p. 55. 



The examples received from Ireland and considered to 

 be those of L. stramineum, Menge, appear to have been 

 wrongly identified, owing to the impossibility at the 

 moment of comparing them with the types of L. nemorale, 

 Bl., which had been mislaid. L. stramineum must, 

 therefore, be removed from the British list. 



Araeoncus crassiceps, Westr. 



An adult male was found on iron railings at Bloxworth 

 Rectory on May 18, 1910, by R. J. P. C. As at present 

 known it is a rare species, but has a wide range.
