^^° This list has been prepared from records obtained from specimens in the collection of the 

 National Museum (US) ; from records sent by Dr. Leonard from the collections in Cornell Univer- 

 sity (CU) and New York State Museum (NYS) ; from records sent by Dr. Prison, taken from 

 specimens in the MacGillivray Collection (MacG-Ill) ; from records forwarded by F. M. Schott 

 (MacG-Schott) ; and from records taken from literature. I have not had an opportunity to study 

 all the specimens from which the records were made. Those obtained from the collections of the 

 National Museum are based, in the main, on identifications made by the writer. Nearly all of 

 the other records are accepted as having been based on correct identifications, and are included 

 with only the necessary nomenclatorial changes. The word "type" after a record does not neces- 

 sarily mean "holotype," but is used in the sense of ''one of the types." The systematic arrange- 

 ment of the groups follows closely the classification proposed by the writer in 1911 (Proc. Ent. Soc. 

 Wash., vol. 13, p. 215—226, 1911). It seems vuidesirable to make any radical changes from this 

 arrangement in a list of this character. The list records 91 genera and 446 species and varieties 

 from the State.
