In the present work it is intended to illustrate those species of American Lepidoptera 

 which have not been figured previously, or which, owing to bad figures, have been 

 re-described and require that attention should be drawn to their synonymy. 



I hope to figure a large number of the species described by Guenee, Walker, and 

 others, but only in those cases where my specimens have been compared with the 

 types. 



Although the work will be devoted chiefly to Heterocera, now and then a Plate 

 will appear of Bhopalocera. 



Should my endeavours to be of use in this interesting branch of Entomology meet 

 with support in the United States, I shall then illustrate a large number of North- 

 American species. 



Where able to do so, I shall also give notes on the earlier stages and transformations 

 of the species. 



Any corrections or suggestions will be most thankfully received by
