106 COLEOPTERA. 



The P. Ratishonensis of Ent. Ann. 1860, appears (by a ! 

 mistake almost inevitable at that time) to be wrongly so ^ 

 named ; it is P. jmnctij^ennisy Fairm. i

A single foreign specimen, without wings, in the collection! 



of M. Aube, and another with wings, taken by Mr. ; 



Matthews in Sherwood Forest, are the only known examples! 



of this species.

testaceo, var. Erichs. 



Mr. Matthews says the ti'ue Ratishonensis is so closely 



allied to P. testacea, Heer, that Erichson is probably right! 



in considering it merely a var. of that species ; but, whether! 



distinct or not, it has been taken in England by Mr. I 



Matthews, and its name must, therefore, be retained in our] 



lists. i 



It has as yet occurred here only in the winged form.
