104 COLEOPTERA. 



colour of the elytra also is usually darker, and the elytra 

 broadly margined with black throughout. 



Found in marshy places, not on or near pine trees, as is 

 always the case with S. discoideus. 



Taken at Southend and Holme-bush by Mr. Waterhouse, 

 and by Dr. Power at Holme-bush, Deal and Lee.

Some members of this genus require no comment, but the 

 following arrangement of our British species is in accordance 

 with the views of Mr. Matthews, who informs me that sub- 

 sequent observations have much confirmed his previously 

 recorded suspicions as to the wings in Ptinella affoiding 

 merely a sexual distinction ; and therefore species, hitherto 

 considered distinct, are coupled together in the present 

 notice ; still further observation is required before this associa- 

 tion can be absolutely confirmed. I am much indebted to 

 Mr. Matthews for his kind assistance in this m.atter.

 It appears that the doubts expressed by Mr. Matthews as 

 to the identity of the Ptinella, taken so plentifully by him- 

 self in the midland counties with the Ratishonensis of Gillm., 

 are now justified beyond question ; also that Mr. Matthews' 

 insect is a new species ; to which, on account of its numerous 

 variations, he has given the name of Proteus.
