Viltle-knoxcn British Spiders. 100 



male is, I think, without doubt L. statlvnm, Sim., the very 

 characteristic palpi corresponding exactly with tlie description 

 and figures of those of that species. The t'eniale is quite 

 another species — Dlplocephalus cristatus^ Bl., in tact. Sonie 

 day J hope to take ilie matter up more tiioroughly; mean- 

 wliile, I iiave little doubt that my present statement is correct.

 the case with all young T. graminicolas ; but in a series of 

 these juveniles several individuals showing exactly tliis 

 condition can generally be found.

 The whole spider is much bleached.
