AMERICAN LEPIDOPTERA. 11 



change from the well and universally known Lhnacodes to Apoda. 

 Several of the species under the typical name in our lists are else- 

 where referred ; but no synonymical changes appear. Sisyrosea 

 (wrongly written Sicyrosea) contains the species inornata, nasoni and 

 rude. It has been shown that inornata is the type of Isa, and not 

 texttda H.-S., though as the name is preoccupied, Mr. Kirby's solu- 

 tion may be accepted. Rude has been referred as a synonym of 

 nasoni. Under Packardia, genus 90, oeellata and nigopunctata appear 

 as good species, though they have been referred to the synonymy. 

 Under Lithacodes we have/a.S'Ctofo., laticlavia and redilinea, referred 

 to Limeodes in my list, and flexuosa, ccesonia and graefii, there re- 

 ferred to Heterogenea. The generic reference in my list may be in- 

 correct, but graefii and flexuosa have been referred as synonyms of 

 textula H.-S. Under Heterogenea, .^hnrtleffii appears as sole American 

 species. If it is really the same as ccesonia, and the latter is really 

 a Lithacodes, this leaves us no representative of this old woi'ld genus. 

 Family XX, the Notodontidse contains 202 genera. Genus 12, 

 Litodonta, with hydromeli as type and sole species, is the first name 

 in our lists. Heterocampa follows, containing our species with two 

 exceptions, elsewhere referred to. H. trouvelotii is given specific rank, 

 though it has been referred as a variety of obliqua, and marina, also 

 given as a species, has been placed as a synonym of unicolor. Under 

 CEdemasia we have the species usually in our lists, and in addition 

 the Dvyocampa riversii Behr. and Edema semirufescens Wlk. The 

 latter was referred to Sehizura unicornis many years ago by Grote 

 and Robinson, as I believe, correctly. Schizura is genus 23, and 

 contains all our American species ; humilis and edmandsii having 

 specific rank, though they have been referred as synonyms to vni- 

 cornis. Genus 25, Saligena Wlk., with its single species personata, 

 has been long ago referred as a synonym of Raphia frater Grt. 

 Seirodonta follows, and contains only the typical species. Hatima 

 Wlk., is next, with semirufescens Wlk. as type, and Dasylophia an- 

 guina and interna as other species. I have, from an examination of 

 the type, referred (Can. Ent. xxiv, 35) H. seinirufescens to Schizura 

 unicornis and the species of Dasylophia are certainly not congeneric. 

 By a lapsus calami I wrote the name Hatuna in my origiiml note and 

 so it was printed. Dasylophia must assuredly be restored. lanassa 

 lignicolor is type of its genus, and Edema transversata is referred to 

 it as a synonym. I have examined the type and have referred it to 

 Ellida gelida Grt. in Can. Ent. xxiv, 135. Genus Syminerista Hiib.
