52) possibly belongs to Meghypena ; cribralis (cribrumalis), perhaps, is a 

 Litognatha (see ante); there remaias rustiealis Zutr., 375-6, as type of 

 Macrochilo. 



Salia. 



1806(1811). Hiibner, Tentamen, 2. 5cjKcaZis, sole species and therefore 

 type. 



1875. Grote, Bttll. Buff. Soc. Nat. Sci., ii, 223. Uses this generic "name 

 for interpuncia and refers salicalis as the type. 



1893. Smith, Cat. Noet., 384, uses this term for interpuncta^nA rufa, and 

 refers to Verzeichniss, 339, for the generic term ; but this is incorrect, 

 as in the Verzeichniss there is no genus of the name ; the latter is 

 there employed only in the plural form to designate a Stirps (Salise). 

 The following is the Verzeichniss name for salicalis : 



COLOBOCHTLA. 



1816 (1825?). Hiibner, Verzeichniss, 344. Salicalis, sole species and there- 

 fore type. 

 The name falls before Salia ; it has only been used by Zeller in 1872. 

 It is misprinted Calobochila by Smith {Cat , 384). Madopa Stephens is 

 synonymous. Zeller writes Colobochila in correction of Hilbner's spelling. 



The ITypenoid Moths of North America and Europe are closely related, 

 so much so, that if the American collector found the European species 

 upon his home excursions in the field, they would hardly present him a 

 form unrelated to what he already knew. Conversely it is but few^ gen- 

 era out of the American fauna which would strike the European collector 

 as "exotic." Perhaps the Southern element in the N. American fauna, 

 genera with a coil of hair on the male antennae, with ^harp apices of pri- 

 maries, is the strangest ; or such odd lormsas Palthis, Dercctis, or Eulint- 

 neria, which have no analogues in Europe. The mass of forms resemble 

 each other in the two worlds and here ag;tin the new is remarkable for its 

 excess in species, as in Bomolocha. Kepresentative species occur freely, 

 as Bomolocha. baltimoralis, Epizeuxis nmericalis, S'dia interpuncta. The 

 occurrence of distinct species of typical Hypena in California belongs to 

 the same class of facts as the occurrence of S.iturnia, and I have offered a 

 probable explanation for this feature of geographical distribution in the 

 order. 



Genera should, ideally, contain species of which the evidence is 

 that they are phylogenelically connected in time. When we study the 

 divergence in representative species we are met with the fact that the pat- 

 tern of ornamentation and then the color have a persistency superior to 

 details of structure, as, for instance, the forms of the genitalia. Genera 

 are opinionative to a certain degree ; as compared with species they have 

 naturally less fixity. Thus the importance of deciding upon a particular 

 species as the type of the generic title becomes obvious. Without this
