14 GROTE — SEARCH FOR THE TYPE OF NOCTUA LINN. [Jan. a, 



as the original "Triibeule." It is unnecessary, having found the 

 type, to follow the fortunes of Hadena further. It was used im- 

 properly by Lederer for a large genus of naked-eyed species separ- 

 able from Mamestra on this character. 



1895. Grote, Ent. Record^ vi, 78. 



Designates cucubali as type of Hadena, and states that Dian- 

 thoecia Boisduval, will probably prove synonymous. 



XYLENA. 

 1806. HuEBNER, Tent., i. 



Lythoxylea (lithoxylea) sole species and therefore type. 



1 81 6. OcHSENH., Schm. Eur., iv, 85. 



Vetusta, exoleta, conformis, lapidea, rizolitha, petrificata, con- 

 spicillaris, patris, spinifera, scolopacina, rurea, hepatica, polyodon, 

 lateritia, lithoxylea, petroriza, pulla, cassinea, nubeculosa, pinastri 

 (scabriuscula), rectilinea, ramosa, lithoriza, hyperici, perspicillaris, 

 platyptera, antyrrhini, linari^, opalina, delphinii. Ochsenheimer 

 quotes Hiibner and spells the genus as he does, Xylena. This is 

 the worst of Ochsenheimer's mixtures and, while enlarging Hiib- 

 ner's genus, the beginning of all subsequent confusion in applying 

 this generic title. This abuse is still being perpetuated, although I 

 gave again the type in 1876. Later writers than Ochsenheimer 

 take out the Lithophanoid forms (Fam. A in part, petrificata, etc.), 

 and use for them a genus " Xylina Ochs. or Tr.," whereas Ochsen- 

 heimer has no generic term so spelled. They then reject the Hade- 

 noid forms (Fam. B in part), which include Hlibner's type lithoxy, 

 lea, instead of the reverse. Hiibner himself, in the Verzeichniss- 

 refers lithoxylea to the same group as petrificata, and the truth 

 seems to be that, perhaps up to Stephens, the generic types I now 

 give to Xylena and Lithophane were thought congeneric or nearly 

 allied. The genus Xylophasia Stephens is a synonym of Xylena 

 Hubner, having the same type. 



(1828) 1829. BoiSD., Eur, Lep. Ind. Afeth., ^6. 



Cites ''Xylina Tr. and Xylena Ochs.," and suppresses Ochsen- 

 heimer's reference to Hiibner for the term. 



(March) 1829. Duponchel, Hist. Nat. Lep., iv, Pt. 2, 72. 

 Gives vetusta as type, but this is impossible.
