genera Stenoptilia and Aciptilia. The third tribe included those 

 species in which each wing is divided into six parts, and these 

 were all placed under the genus Euchiradia, which is of course 

 synonymous with Orneodes. 



In 1827, Curtis published Vol. IV. of his " British Entomology/' 

 in which he adopted the genus Pterophorus and names pentadactyla 

 L. as the type. In Vol. X. of the same work (1833), he estab- 

 lished the genus Adactylus with adactyla Hub. for the type. In 

 Vol. XV., published in 1838, he adopted the genus Alucita and 

 named hexadactyla as the type. Curtis, in 1829, in his "Guide 

 to an arrangement of the British insects," had taken the genus 

 Adactylus for the species with undivided wings, Alucita for ' ' hex- 

 adactyla and its allies " and Pterophorus for the remainder. In 

 the same year Stephens published his "Catalogue of British in- 

 sects," in which he adopted the genus Agdistis Hub. for the species 

 with undivided wings, and Pterophorus and Alucita in the same 

 sense as Curtis had used them. This same classification was 

 used by Stephens in 1834, in his "Illustrations of British En- 

 tomology." 



Treitschke, in Vol. IX., Part 2, of his " Schmetterlinge von 

 Europa," published in 1833, adopted the generic name Alucita for 

 the species placed by Stephens under Agdistis and Pterophorus, 

 while he used Orneodes for hexadactylus and its allies. In 1836, 

 Duponchel, in his " Histoire naturelle des Lepidopteres," Vol. IX., 

 adopted the classification of Latreille, but in his " Catalogue 

 Methodique," published in 1844, he used the genus Adactyla Zell. 

 for hubneri Curt., Orneodes, for hexadactyla and its allies, and 

 Pterophorus for the remaining species. West wood, in Vol. I. of 

 his "Classification of insects," page 115, published in 1839, 

 adopted the classification of Stephens. 



Zeller, in 1841, published his monograph of the plume-moths 

 in " Isis," Vol. X. This author adopted the name Pterophoridcz 

 for the group, and divided them into the Pterophoridce proprii, and 

 Alucitina. Under the first division he established the genus Adac- 

 tyla, apparently unconscious of the fact that Curtis had already 

 used the same name. Under this same division Zeller adopted the 

 genus Pterophorus Geoff., which he divided into groups or sub- 

 genera as follows: Platyptilus (Platyptilia Hiib.), Oxyptilus (Am- 

 Uyptilia Hiib. ) , Pterophorus (Stenoptilia Hub.) , Aciptilus (Aciptilia 

 Hiib.). The division Alucitina contained the genus Alucita with 

 hexadactyla and allies under it. In 1852, Zeller published his 

 *' Revision of the Pterophoridae " in " Linnaea Entomologia," Vol.
