TYPES OF NOCTUID GENERA. 



BY A. RADCLIFFE GROTE, A. M., HILDESHEIM, GERMANY. 



I refer the student to papers of mine on this subject in The Ento- 

 mologisfs Record, Vol. VI., pp. 27 and 77. The principal types given 

 by me for genera found in North America are as follows : 



Agroiis, Hiibn., 1806, type : A. segetum. 



Graphiphora, Hiibn., 1806, type : G. gothica. 



Goriyna, Ochs., 1816, type: G. micacea. 



Oc/iria, Hiibn., 1S16, type : O. flavago (ochracea). 



Hylena, Hiibn., 1806, type: X. lithoxylea. 



Lithophane, Hiibn., 1816, type: L. socia (petrificata). 



Hadena, Schrank, 1802, type : H. cuciibali. 



Heiioscota, Grote, 1895, ^yP^  ^- miselioides. 



Acontia, Ochs., 1816, type : A malvaj. 



Eusiroiia, Hiibn., 18 16, type : E. unca. 



Copimainesira, Grote, 1883, type: C. brassicse. 



Oiigia, Hubn., 1816, type : O. strigilis. 

 I now give the literary evidence for the types of: 



Liiperina, Boisd., 1829, type : L. testacea. 



Ledereria, Grote, 1874, type : L. virens. 



Apainea, Ochs., j8i6, type : A. didyma. 



Hydroecia, Guen., 1841, type : H. nictitans. Linn., sp. 



Ledereria. 

 1874. Grote, Bull. Buff. Soc. Nat. Sci., 54. The name is proposed 

 generally for Ijiperina, Led., nee Boisd. The type virens is after- 

 wards given in Entomologist's Record, VHL, 183 (1896). 



Hydroccia. 

 1841. Guene'e, Noct. Eur. Index Meth., Ann. .Soc. Ent., Fr., Tom. X, 

 237 : cupra^a, leucostigma, micacea, nictitans. No description ; 

 no type given. 



These are the original species of vT^/^/rar/V?/ cnprcea (cuprea) 

 is an Agrotis ; leucostigma was taken afterwards in 1857 by Lederer 

 as type of Helotropha ; micacea became in 18 16 type of Gortyna, 

 Ochs.; nictitans appear.s to be hardly generically separable from 

 micacea. Leucostigma would be therefore type of Hydrcecia, and 

 Helotropha falls ; the only alternative is to make nictitans type, and 

 f-levate this into a genus, which course I adopted in 1874.
