1 It is due to a mistake that MOrcu (loc. cit.) says “SpENGLER citirt mit Unrecht Chemn. f. 864—66, 
die eine Martesia ist,’ as it is the same specimens from the collection of Spengler, which CHEMNITZ 
1785 describes and figures (under the name of P. striatus L.?) and SpeNnGLer afterwards (1792) de- 
scribes as P. quadrizonatus. These specimens are still in existence in the Museum of the University 
of Copenhagen.
