The Council of the Plymouth Institution and Devon and Cornwall 
Natural History Society being desirous to embody, in the Annual Eeports, 
a Catalogue of the Fauna and Flora of the two counties, the following is a 
third instalment of the Lepidoptera. The Rhopalocera, and the first and 
second groups of the Heterocera (the Sphingina and Bombycina) hjive 
already been catalogued. 
The insects treated of in the following pages comprise the whole of the 
species of the group Noctuina that are known as natives of Devon and 
Cornwall. 
This third portion of the Catalogue has been prepared mainly from the 
original notes and observations of the writer, who has been assisted (with 
respect to distant habitats) by reliable correspondents ; printed books having 
been referred to only when other authority was wanting. 
The arrangement adopted is that of Stainton's '* Manual of British 
Butterflies and Moths," — selected in consequence of its being not only the 
latest complete work on the British Lepidoptera, but also the most accessible. 
When initials are appended, the writer is indebted to his correspondents, to 
whom he takes this opportunity of returning his warmest acknowledgments. 
The following contributors' names are abbreviated in the Catalogue, as in 
the subjoined list : — 
Dr. Battersby, Torquay Dr. B. 
Dr. Cocks, Falmouth (contributions towards a Fauna of 
Falmouth) Faun.Fal.
