' It is due to a mistake that Mörch (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 Spengler afterwards (1792) de- 

 scribes as P. quadrizonatus. These specimens are still in existence in the Museum of the University 

 of Copenhagen.
