The small I^Joctuae differ so considerably from each other, 

 that reasons might be given for separating them much further 

 than they have been ; but as their economy is at present not 

 well known, and I do not possess all the species, I have in- 

 cluded A.fuscula and its congeners with N. caliginosa of Hub. 

 with which it associates better than with Erastria. They may 

 be thus divided : — 



I. Abdomen rather short. 

 * Smooth on the back. 



1. A. venustula Hub. 60. 294. Haw. 261. 21. 



This beautiful little moth I had the pleasure of taking the 

 10th of last June, in the neighbourhood of Bordeaux; it was 

 flying in the evening on a common amongst bushes outside 

 a plantation. It is very rare in England, but is said to have 

 been taken in Epping Forest some years since ; and it appears 

 to be as uncommon in France, for it is not recorded as a na- 

 tive of that country in the work now publishing by Mons. Du- 

 ponchel. Some, if not all, of the Erastriae are day flyers, which 

 induced me in " The Guide" to remove A. venustula a,udfus- 

 cula, which are night flyers, to another group. 



2. A. apicosa Haiv. Lep. Brit 261. 20. In Mr. Haworth's 



cabinet. 



* Abdomen tufted down the back. 



3. A. fuscula Huh. Curtis's Brit. Ent. pi. 356. — fusca Haw. 



— albilinea Haw. 261. 19. var. 

 Found at Colney-hatch, Coombe and Bexley woods, Chis- 

 sel hurst, the New Forest, and in corn-fields, in June, at 

 Wrentham, Suffolk. The caterpillar, which feeds on the 

 common bramble (pi. 72.), is copied from Hubner. 

 II. Abdomen long. 



4. A. caliginosa Hub. 100. 474. — June, in the New Forest. 



5. A. lutescens Haw. 260. 15. — July, near Lyndhurst, Hants. 



6. A. rufa Haw. 260. 16. — rufula Curt. Guide. — Taken in Nor- 



folk, and at Whittlesea Mere. 



7. A. arcuosa Haw. 260. 17. Common the end of June, in 



meadows, Copenhagen-fields, Epping, &c. 



Mr. Haworth having allowed me to see his Noctua scopu- 

 lepesy I believe it to be more nearly allied to the genus Ophiusa 

 than to any other group. 



Rubus ccEsius (Dew-berry Bush) in fruit accompanies the 

 insects.
