1 62 ox NEW AND RARE BRITISH SPIDERS. 



For synonyms and other information upon the spiders in the 

 foregoing list see "Spiders of Dorset," 1881, and papers on 

 British spiders subsequently published in the " Proceedings " 

 of the Dors. N.H. and A.F. Club, 1S82-1902; also see "List 

 of Brit, and Irish vSpiders," 1900. 



Notes and Descriptions of Some of the Spiders 



IN THE ABOVE LiST. 



Theridion impressum, L. Koch. Fig. 2. 



Thcridion impirssiun, L. Koch. Abhandlungen der Natur- 

 forschenden Gesellschaft zu Gorlitz, Band, XVII., p. 45, pi. II., 

 fig. I.

 The only British example yet recorded is that lately sent to me, 

 an adult male, from near Stratford-on-Avon by the Rev. J. H. 

 Bloom. In Hungary it is said by Professor Kulczynski, of 

 Cracow, to be found in equal abundance with T. sisyphium, Clk., 

 which latter is also a widely distributed and common species in 

 England. 



Laseola jucunda, sp.n. Fig. 3. 



Adult male, length i line. Adult female, i^th. 



In general form, colours, and appearance this species is very 

 like Laseola inoniaia, Cambr., with which it has hitherto been 

 mixed up. It may, however, be readily distinguished by the 

 posterior row of eyes being very nearly straight or with only a 

 very slight curve ; while that of inornata is strongly curved, the
