') The species described by Hy. Edwards as Stretchia pl usii f ormi s, 

 I have originally referred to the Agrotid g'enus Perigrapha. la their 

 ßynonymic revision of bombycine Moths, Neumoegen & Dyar credit Hy. 

 Edwarde, exclusive of varieties, with 33 species against 38 Synonyms ; Wallcer 

 ■with 35 species against 54 Synonyms; Packard with 3i species against 32 

 Synonyms; Grote (incl. G. & R.) with 72 species against 29 Synonyms. Tho 

 Americans had a more ideal motive for their work, since, according to Smith, 

 Walker received a Shilling a piece for his descriptions, the Latin thrown 

 in, but the Synonyms paid for in specie as good species. For a list of 

 the North American Platypterygidae, Saturniidae, H emilcucidae, 

 Citheroniidae, Cossidae and Hepialidae consult also Grote, Proc. Am.
