AMERICAN LEnUOPTERA. (7 



(In the Museum of the J:irdin des Plantes, inauy of the Sphingidac 

 are under unpublished MS. names of Dr. Biisduval's. The foUowinji- 

 are superseded by Mr. Walker's descriptions: Brdcsid /iipp(irsiiKj^=: 

 Cautethia noctuiformis, (Walk.), Grate; FachjjUa ^r/.s^/,s |=Pachylia 

 resuraens, Walker. Anrer/jx piperls ^ is = Dilophonota einerosa, 

 G. & R.; A. andae ^ and .1. si/eitus \. belong to the first group of Di- 

 lophonota, Burin. ^ and are allied to the Cuban D. rimosa, G. & R. 

 Other apparently unpublished MS. names in other families are : lo 

 ya6j'tc'?Y^^=Hyperchiria varia. Walk., (^Saturnia io \. Harris); Spllo- 

 soma vefocipedum\.=Sp\\osoma, virginalis. Pack., (this name might be 

 retained for the Californian species of Spilosoma, since that chosen by 

 Dr. Packard has been too frequently used in nearly allied genera in 

 the Arctiinae) ; Hcdisidota sa^i'r<s^=Hal. californica. Walk. Addo- 

 cephala raspa ^^x\delocephala albolineata, G. & R. The S of A. 4- 

 lineata, n., is in Mus. Berol.; the antennae pectinate.) 



Part IX.— 1856. 



DijjJitera jocosa, Walk., p. '66, belongs to Moma Hiibn. This spe- 

 cies, originally described by Guenee under the genus Diphtera, Ochs., 

 is subsequently figured by Herrich-Schaeffer as Moma fallax. Walk- 

 er's var. /3 : Thorax ccrvino-albidus ; alae anticae albidae, punctis 

 fasciisque duabus latis (In diffum ) nigris — is a faded specimen, 

 with the black bands contorted. This specimen seems from the eti- 

 quette to have been the type of M. Guenee and is an extreme variety 

 or abnormal form of Herrich-Schaefi'er's M.fidlax. 



Acronycta PsiX Walk., (p.) p. 42=Acronycta occidentalis, G. & R. 



Acronycta longa Walk. var. (nee. Guen.) p. 60=Acronycta nocti- 

 vaga, Grote. 



Mythimna contraria, Walk., p. 78=Ceramica exusta, Guenee. 



Leucania extranea, Walk., p. 93=:Leucania unipuncta, Haw. 



Eudryas Stae. Johannis, Walk., p. 144. This beautiful species is 

 allied to our North American E. grata, but is very obviously distinct 

 from it. The species is not improbably South American ; so far at 

 least it has not been discovered within the limits of the United States. 



Feltla ducens Walk., p. 203z=Agrotis subgothica. Haw. 



Mamestra unicolor, Walk., p. 233=:Noctua clandestina, Harris. 



Mamestra ordlnaria, Walk., p. 232=Mamestra devastator. This 

 species has received several names. It is the Ayrotis devastator of 

 American Authors.
