54 ON BRITISH ARACHNIDA. 



pi. xlvi., Fig. 10). Its chief generic distinction seems to 

 be based upon the armature of the underside of the tibiae 

 and metatarsi of the legs, which appears to be a good 

 distinction, though it is chiefly marked in the female, 

 and in that sex most strongly on the anterior legs, while 

 in the male it is not so remarkable.* 



Hypselistes florens, Cambr. 



Erigone florens, Cambr., Proc. Zool. Soc., Loiid., 1875, 

 p. 403, PI. xlvi, Fig. 10. Both sexes adult were received 

 lately from the Rev. J. E. Hull ; these were found by 

 Mr. Hull's nephew (Mr. H. H. Harrison) in swampy 

 places on the ancient jet workings on Eston Moor, 

 Cleveland, Yorkshire. The occurrence of this fine 

 and very distinct species in Yorkshire is of great interest, 

 as it has not been recorded in any locality until now since 

 its record in 1875 in North America, where it appears to 

 be an abundant form. It is new to the British fauna. 



Hypselistes Jacksonii, Cambr. 



Entelecara Jacksonii, Cambr., Proc. Dors. N.H. and 

 A.F. Club, XXIII., 1902, pp. 24 and 23, Fig. 6. 



Taking the armature of the legs as generically distinc- 

 tive, Entelecara Jacksonii, Cambr., should, I think, be 

 removed to the genus Hypselistes, Sim. Others of the 

 genus Entelecara show a somewhat analogous, though 

 not similar, armature, w r hile in one or two species the 

 legs are normal. Further consideration seems necessary 

 to determine the position of the different species of this 

 now somewhat heterogeneous group. 



* M. Simon says, I.e., simply " tibiis anticis subtus satis longis biseriatis 

 instruct!." All the legs, however, metatarsi as well as tibiae, are more or less 

 well-marked in respect of this armature. In Arachnides de France V., p. 617, 

 M. Simon includes E. florens, Cambr., in the genus Nemalognus, Sim., with 

 the type of which, however, E. florens, Cambr., has only a somewhat similar 

 general form of the male palpus, but 110 other good affinity.
