From the above references it will be seen that the P. midamus of 

 Linnseus has hitherto been identified with this species. This erro- 

 neous determination has been caused by Linnseus himself referring, 

 in his original description of P. midamus (Syst. Nat. 1758, p. 470), 

 to Ehret's figure on plate iii. as well as to that on his plate xi., and 

 in the Mus. UlricEe, p. 251, therein supplementing his description 

 of P. midamus with that of the present insect. 



For true P. midamus, Linn., see below, p. 312.
