C. phalaris was described by Fabricius from tbe cabinet and Icones of Mr. Jones, 

 whose figures were publisbed by Donovan in bis ' Naturalist's Repository.' The Fabri- 

 cian description is simply " alse supra fuscse, anticse immaculatse, posticse fasciis duabus 

 fere marginalibus e maculis exalbidis." Godart applied the description of Fabricius to 

 the insects subsequently described and figured by Dalman under the name of P. mygdon, 

 with which, indeed, the two rows of spots on the outer margin of the hind wings 

 described by Fabricius agree both in form and colour.
