XII. A Revision of the American Notodontidie, 

 By William Schaus, F.Z.S. 



[Read June 5th, 1901.] 



Plates XI and XII. 



In the present revision of American Notodontidte I have 

 omitted the Melalophidse as separated by Mr. Dyar, and 

 hope on some future occasion to give this sub-group my 

 attention. Besides the types in the British Museum and 

 at Oxford, I have been able to examine the types figured 

 by Felder, those described by Mr. Dognin, and very nearly 

 all described by Mr. Herbert Druce. I have not referred to 

 Hetcrocampa mariva, Dogn., IT. nea, Druce, and H. volana, 

 Druce, which are Noctuidse, and likewise a number of 

 species included in the Biologia Centrali-Americana, and 

 Kirby's catalogue under the Notodontidie, as they belong 

 to other families. The types of a Dumber of Walker's 

 species described from the Fry collection are lost, and so 

 far as I am able to identify them from the description, 

 they belong to other groups. Peroma anomala, Sureta 

 tripars, Scmega orcus and Sidana bifascies may all refer to 

 species of Hemiceras. Burmeister in his Atlas, PL xxii. 

 fig. 2, figures the larva of an Awwrocampa camelinoides — 

 A. canovaria, Walk., and fig. 3, A. vomax, which he 

 believes to be A. melanostigma , Walk. Walker described 

 a Naprepa camelinerdes, and the figure may refer to this 

 species, but A. canovaria, Walk., is evidently a species of 

 Hydrias, and A. melanostigma a species of Titya, so fig. 3 

 no doubt refers to a new species, or it may eventually 

 prove to be Naprepa elongate, Schs. I have not always 

 given the synonymy of the North American species, as 

 they have been so admirably worked out by Professor 

 Packard. At Rennes I have examined Guenee's types 

 of the genus Hemiceras, and have carefully compared 

 specimens of all the species in my collection. I have not 

 seen Moschler's types, but his descriptions arc all that 

 could be desired.
