that the European species must be revised. They fit in everywhere with 

 the American. The question is further narrowed by the apparent fact 

 that barbalis and tentacularia are types and sole species ; they stand 

 alone by themselves, none of the species heretofore associated with 

 them having strictly the same structure or combination of characters. 

 Were their generic distinction not admitted, the term Polypogon would 

 have to be used for a combined genus, and Herminia be dropped. Should 

 Polypogon be preoccupied, then the combined genera would take the 

 name Herminia, since this is earlier than Erpyzon of Hiibner. 



Erpyzon. 



1806 (1811). Hiibner, Jentamen, 2 : barbalis. This is sole species and 

 therefore type. 

 The term, being later than Schrank's or Latreille's, falls before either. 

 It could only be used in the case, that barbalis and tentacularia being 

 held to belong to distinct genera, Schrank's term for the former proved 

 unavailable. 



Paracolax. 



1816 (1825). Hiibner, Verzeichniss, 844 : tarsicrinalis (barbalis in error), 

 tarsiplumalis, grisealis, devialis. 

 This term might have been used instead of Zanclognatha by Lederer, 

 since this author refers devialis to Herminia, and includes all the rest in 

 his new term. A discussion of the type follows later. 



Pkchipogo. 



1816 (1825 ?). Hiibner, VerzeicJmiss, 345 : barbalis (plumigeralis in error), 

 pectitalis. 

 This name, altered to Pechipogon, is erroneously used by Lederer and 

 Staudinger for barbalis. Pectitalis, unknown to me, may be the type. 



^THIA. 



1816 (1835?). Hiibner, VerzeicJmiss, 339 : emortualis, circulata. 



For this name circulata is type. Guenee takes out emortualis as the 

 type of Sophronia, which Speyer wrongly records as a synonym of 

 ^thia. 



The following is an attempt to arrange the Palearctic species. Unfortu- 

 nately I have only part of the European and no American specimens at 

 the moment Ibr study : 



1. Male antenna; thickened or nodose, palpi recurved, fore legs modi- 

 fied and tufted : Zanclognatha tarsiplumalis, tarsipennalis and the Ameri- 

 can species. 



2. Male antenna? not thickened, palpi recurved, fore legs modified and 

 tufted : Faracolax grisealis, tarsicrenalis. Grisealis may be type. 



3. Male antennae with very short pectinations, palpi in the male bent
