published in 1796, page 148, separated hexadactyla from the group 

 and established for it the genus Orneodes, but retained the rest of 

 the plume-moths under Pterophorus. Latreille repeated this use 

 of these generic names in his l i Histoire naturelle des Crustaces et 

 Insectes," Vol. XIV., page 255 (1805), and used the generic name 

 Alucita in the Fabrician sense. This action of Latreille in remov- 

 ing hexadactylus from Pterophorus left only the species monodacty- 

 lus L. under it which must now be regarded as the type, while 

 Orneodes must be recognized with hexadactyla L. as the type. 



In 1806, Hiibner published his " Tentameu," in which these in- 

 sects are placed in Phalanx 9 ; Alucitae, in Tribus 1 : indubitate. 

 There are two divisions under this, the first of which is Ptero- 

 phorse with Pterophora pentadactyla, and the second is Ripidophorae 

 with Ripidophora hexadactyla. The "Tentamen" has caused a 

 great deal of controversy as to whether it was a true publication, 

 and whether its generic names should be recognized. No question 

 can arise in case of the plume-moths, as Poda had long before 

 adopted pentadactyla as the type of Alucita, and Latreille had 

 very properly separated hexadactyla from the group and estab- 

 lished for it the genus Orneodes. Schrank, in the second part of 

 Vol. II. of his "Fauna Boica" (1802), page 139, adopted the 

 Linnsean genus Alucita for these insects. 



In 1811, Haworth published the third part of his " Lepidoptera 

 Britannica," in which he adopted the genus Alucita in the Liunaean 

 sense for the plume-moths. In 1815, Leach published his article 

 " Entomology " in the "Edinburgh Encyclopaedia," in which, 

 under Tribe VII, Alucitides, the genus Pterophorus Geoff, is 

 adopted with pentadactylus and didactylus under it, and the genus 

 Alucita with hexadactyla under it. In 1819, Samouelle published 

 his "Entomologist's Useful Compendium," in which he adopted 

 the classification of Leach. 



Hiibner, in his " Verzeichniss bekannter Schmetterlinge," 

 adopted the term Alucitae for his ninth phalanx, the plume- 

 moths. This part of the "Verzeichniss" was published between 

 Aug. 27, 1825, and the time of Hiibuer's death, which occurred 

 Sept. 13, 1826. This author divided these insects into three 

 tribes : the first including those with unfissured wings, for which 

 he established the genus Agdistis ; the second with those having 

 one fissure in the fore wings and two in the hind wings. This 

 tribe was further divided into two families, each containing two 

 genera. The first family, Obtusae, contained the genera Platyptilia 

 and Amblyptilia, and the second family, Cuspides, contained the
