PLATE XXXIX. 



This species is found in several countries of Europe. In Great 

 Britain it seems to be a local and rather uncommon kind. Da Costa 

 says " though found in many parts of England, is not met with in 

 any plenty, but is scarce. I have found them on the rocks, at and 

 near Matlock, in Derbyshire, about Bath, in Somersetshire, also on 

 rocks; in Surrey, Wiltshire, and Hampshire, in the moss on the 

 bodies of large trees, and in woods. Dr. Lister found them on the 

 grass in Lincolnshire ; Mr. Petiver, in hedges, between Charlton 

 and Woolwich, in Kent * ; Mr. Morton, in hedge-bottoms, in Oakly 

 Parva, in Northamptonshire ; and Mr. Wallis, on the rocks in Nor- 

 thumberland : but they are not common or frequent any where."
