* Named after Mr. Edgar L. Layard, who was for several years resident in Ceylon, during Sir 

 Emerson Tennent's governorship, and who made a cousiderable collection of the Lepidopterous insects of 

 the island. Mr. Layard's collection formed the basis of the List of Insects enumerated in SirE. Tennent's 

 " History of Ceylon," published in 1859, and contained the type specimens of the numerous new species 

 described by Mr. Walker in the British Museum Catalogues. It would be of great service to the Author 

 if the whereabouts of this collection could be traced, and its contents thus be made available for the 

 present work.
