AMERICAN LEPIDOPTKRA. 7 



is entirely unnatural, and without any base discoverable by me. 

 Stretchii is separated by shastaensis from intermedia, of which it has 

 been referred a synonym. Shastaensis, by the bye, is credited to 

 French instead of Behr., and quite correctly, for the characterization 

 is by French, and the use of a mss. name suggested by another does 

 not change the authorship. Other departures from well-established 

 synonymy are numerous, and Mr. Kirby seems to have been quite 

 arbitrary in his recognition or rejection of species. All of Mr. But- 

 ler's names, baseless as most of them are, stand of course, since the 

 types are in the British Museum, but why anna and persephone 

 should be kept distinct when no American entomologist disputes 

 their specific identity is puzzling, especially when nevadensis and 

 incorrupta, which are related in much the same way, are classed as 

 varieties. 



Under Orodemnias we find quenselii with gelida as synonym, spe- 

 ciosa as a good species, ohliterata and cervinoides. In Callaretia we 

 have ornata, proxima, favorita and arizoneasis. Under proxima, 

 which is not credited to our fauna, we find docta, mexicana and an- 

 theola, as synonyms, correctly enough ; arizonensis should have been 

 added. 



In Leptardia the names are arranged according to French and 

 Butler. 



Family IX, the Cyrabidae, contains only one familiar name — Earias 

 obliquata Hy. Edw. It seems to be the only species in the family 

 recorded from the New World, and the correctness of the generic 

 reference may bear investigation. 



Family X is the Lithosiidae, with 228 genera not divided into sub- 

 families. The first familiar name is genus 11, Hypoprepia, under 

 which our species are arranged as we are accustomed to see them. 

 Genus 12, Cldhen.e, contains all the names proposed for our forms, 

 and specific rank is accorded to all. Genus 13, Pyralidia, replaces 

 Byssophaga, as used in our lists, and deserta Felder, from Utah, is 

 named as type. I do not know this species and question its distinct- 

 ness from our other named forms. 



Genus 14 is Hyalo^cotes i'or fumosa Butler, and then there is a long 

 array of genera without a familiar name until 92, Lithosia, is reached. 

 Here we find argillacea with bicoloi- as synonym, and ruhropida. 

 Why argillacea is preferred to bicolor does not appear : both names 

 were proposed in the same volume of the same publication, but bi- 

 color has, according to Mr. Kirby, twenty-four pages the priority,
