*) I have taken for the type of tliis poiius an ordinary form commonly 

 occurring for purposo.s of coniparison. The sj)ccie8 hcrc included are tlio.se 

 placed by Smith in II ade na, with the remark that thoy probably belon^j; 

 to mor(! than one f.'eneric tyi)('. Thcy are in fact my fornior geiiiis II ad e n a, 

 niinuH the species «eparatcd by Smitli under Xylophasia. The type of 

 II ade na Schrank is, as I have ascertained, the European cucuhali, a form 

 witli hairy (^yes and referred by Hoisduva! to Dianthoecia. In no event 

 can the term Iladena be applied correctly to any of the species of 

 liadena in eensu Led. Our specieb need revision. Those agreeiiig with 

 X. lithoxylea niust he separated niider Xyleua. Tho.se apreeing with 

 Ü. Btrigilis must he j^eparated under Oligia (— M i a n a Steph). There 

 remaiiiH a rcsidue for whieh I have ])ro|)o.seil the tcrni Ilclioscota. The 

 type of Celaena is Uaworthii, a bpecien included under Luperina 

 Led., but which is not Luperina of ßoisduval. The penera Ilillia and 

 Achatia, ]>la(M'd hen^ l)y Smith, are out of i)lace, hut the object of thi.s 

 Liht is not to revise the bt'fjuence of the species or genera. The American 

 genus Peeudanarta is closc to Helioscota. The name was proposed 

 by mo in iettcrs to lly. Edwards, then in San Francisco, for his Anarta 

 crocea, a form which is at least a good variety of my previously described 

 liadena flava. 1 have not seen his jtaper quoted by Smith, Proc. Ac. 

 Sei. Cal., C, Liij, 1875.
