ON SOME RARE ARACHNIDS 73 



Chiridium museorum (Leach). Mr. Varty-Smith found 

 several adults under pieces of mortar in a barn at Newton 

 Arlosh, Cumberland, in October. In September I obtained 

 several specimens amongst refuse in the same cowshed 

 in which C. riifeolus (Sim.) occurred. The present species 

 occurred upstairs in the loft, and the latter on the ground 

 floor. Fly papers were hung up in both situations, and 

 on them flies of various species were caught, but in no 

 case was either of the species of Chernetid found attached 

 to them. 



Roncus lubricus (L. Koch). A single example from 

 Reading. Mr. F. J. Cole. 



Chthonius tetrachelatus (Preyss.). Mr. Bagnall found 

 both sexes under boards in cool greenhouses at Newcastle 

 in October. In November I obtained examples in similar 

 situations in Dickson's Nurseries, Chester. 



Chthonius tenuis (L. Koch). Mr. Bennett found about 

 a dozen examples amongst fallen pine needles near 

 Hastings, and at Bexhill. He also obtained an example 

 at Esher in Surrey. The species occurred both in autumn 

 and early summer. 



Chthonius Rayii (Koch), Mr. Bagnall obtained this 

 animal in July at Bishopston in Clydesdale. I found one 

 or two specimens in June in the Isle of Portland. All 

 these examples were found under stones.
