names of two others have been inserted in our indi-

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, 
it is not improbable that they may likewise inhabit 
this country, and we have therefore subjoined their 
distinctive characters.
