ON SOME RARE ARACHNIDS 63 



female in Yorkshire, and of both sexes from County Carlow. 

 I also give figures of the vulva, as there are none in British 

 literature. G. pagamim is recorded by M. Simon* for several 

 localities in the South of France. 



Eplblemium affinitatum (Camb.) Plate IV., figs. 4, 5, 

 6, and 30a. 

 A male and female were captured by Mr. W. H. Bennett on 

 the trunk of a tree in Richmond Park, Surrey, in June. The 

 species was described (but not figured) by the Rev. O. Pickard- 

 Cambridgef from a male obtained in Dorsetshire in i860. 

 The female is new to Britain, and the present male is only 

 the second on record for this country. I give figures of the 

 palpi, and it will be seen how entirely the tibial apophyses 

 differ from the corresponding structures in E. scenicum (Clerck) 

 and E. cingulatmn (Panz.). I also give drawings of the vulvae 

 of all three spiders to illustrate the fact that there is no 

 difficulty in distinguishing the females of our three species of 

 Epibletnium. Further, I show the comparative lengths of all 

 three, of which the present is distinctly the smallest, my male 

 being only 3*25 mm. in length, whilst examples of ^. cingulatum 

 and E. sce/n'cum measured 5 mm. and 6 mm. respectively. 



On sending these spiders to Mr. Cambridge, he at once re- 

 cognised the male as being identical with his type of E. 

 affinitatvm (Camb.). The female was new to him, and as it 

 was captured in the same locality as the male, and corres- 

 ponds with it in general characters, they may reasonably be 

 considered as conspecific. The specimens were then dis- 

 patched to Professor Kulczynski, who declared them identical 

 with E. zehra7iev7n (C. L. Koch.) But the original types 

 of this species are not available ; probably they are lost. 

 Mr. Cambridge, however, has compared the present examples 

 with E. zebranettm (C. L. Koch — L. Koch), E. zebj-afietim 

 (C. L. Koch — E. Sim.), E. tenet-nm (C. L. Koch — Camb.) 

 and other Continental species, and states that E. affinitatum
