This interesting addition to our Fauna has been taken sparingly 

 by Mr. Edward Saunders off dwarf sallows at Woking. It is the 

 largest species of the genus that we possess at present, and the male 

 is remarkable for the great development of the characteristic form of 

 the genital plates, of which the narrow apical portion is bent upward 

 at a right angle to the body of the plate, and forms the " appendice 

 erecta acuminata " of J. Sahlberg.
