20 THE entomologist's kecord. 



George Hampson in the " Cat. Lep. PhalaBnse of the Brit. Mus." has 

 " in every instance, irrespective of the work of any previous entomo- 

 logist, fixed the type of each genus, when not particularly specified by 

 the author, as the first species placed under the generic name," 

 resulting in many instances in most confusing interchange of generic 

 names. All the principal genera are dealt with in detail. It must be 

 noted that McDunnough disregards the Tentamenoi Hiibner. The old 

 conception of most of the genera has been conserved by these 

 researches.
