 doubtful authority of a single specimen of each, said 

 to have been found many years ago by Mr Palstead. 

 As both species are abundant on the continent, ex 

 tending even to the more northern parts of Sweden, 

 U is not improbable that they may likewise inhabit 

 this country, and we have therefore subjoined their 

 distinctive characters.
