Platyphora. 441 



new proof has been given, as Malloch (Biill. 111. State Lab. Nat. 

 Hist. XI, 1915, 353) has described an American Platyphora, of which 

 he had taken a pair in copula, the female being quite like the Aenig- 

 matias. Concerning the whole story of the species I, for the rest, 

 refer to the papers cited published by Donisthorpe 1914 and Schmitz 

 1915. On a specimen of the female from Scotland, which is darker 

 in colour, greyish black, Schmitz has founded a var. highlandica.
