APATELA LEPORINA Linnaeus, van MOESTA Dyar. 



Six specimens, June 13, July 2, 21, 27. A very distinct form of 

 the European species. The color is dark gray, fully as dark as 

 canadensis Smith and Dyar, which it much resembles; but the basal 

 lino is broken and the transverse posterior line 's dentate as in eastern 

 leporlna. The larva^ agnn- in type with leporina, ])ut the head is darker, 

 often strongly marked with black. None of the American forms of 

 leporlna agree exactly with the European. Wc sceiu to have three 

 races, which I would list as follows: 



Apalela leporlna Linna'us Europe.
