LIST OF TFIE NORTH AMERICAN PLlTYPTERICES, ATTACI, 

 HEMILEUCINI, CERATOCAMPAD^, LACHNEIDES, TEREDI- 

 NES AND HEPIALI, WITH NOTES 



By Aug. R. Grote. 



{Read before the A:nerican Philosophical Society, Nov. 20t7i, 1874.) 



In this list, I present the results of ray studies on a portion of the 

 North American Bombyces. The admirable synopsis of the Family by 

 Dr. Packard, I have found ou^r best authority on the subject, while I 

 have been able to propose many necessary and important changes in 

 nomenclature from more extended bibliographical researches. The 

 only changes from Dr. Packard's classification here made, are the 

 division of the " Hepiali " into two groups, in which I follow Hiibner, 

 and the disintegration of the " Ceratocampadse " into Hemileucini and 

 Ceratocampadse indicated by Mr. Robinson and myself in 1866. To Mr. 

 S. H. Scudder we owe the reprinting of the Tentamen of Hiibner and, 

 more recently, the discovery of the exact date* (1806) of that valuable 

 document. 



In the present List, a star (*) is prefixed where the genus is represent- 

 ed in Europe ; a dagger (f ) where I have been unable to examine the 

 species myself. 



Bombyces Linn. (1788). Bombycm Borkh., 1798 ; Bombyces Hiibn., 

 1806; Bombycites and Noctuo-Bomhycites Latr., 1810 ; Phalaenml^vihx^., 

 1816. 



PLATYPTERICES Hiibner (1806). 



PlatyptericidcB Stephens, 1829 ; Platypterygino! Grote, 1868. 



* Platypteeyx Laspeyres (1802), 



Type : Bombyx hamula S. V. 



Note. — ^Htlbner, in his Tentamen, first restricts Laspeyre's generic term to this type. 

 Since Schranlt's genus Drepana (ISOl), contains species not congeneric with this type, 

 iiis name, while earlier, must be used for one of these, and Hilbner's restriction of Las- 

 peyre's later term must be respected according to the rules of Zoological nomenclature. 

 This restores my original determination (1862) for our American species. Stephens' 

 " Drepana fasciata," is probably a species of Vrepanodes, from the description.
