204 THE ENTOMOLOGIST. 



M. sociata (suhtristata), Emmelesia alhulata ; and at sugar two 

 Dicycla oo ; also Thyatira batis, T. derasa, and Cymatophora 

 cluplaris ; and as July drew on, Dipterygia scahriuscula (innastri); 

 and among those to be mentioned as numerous were Noctua 

 augur, N. festiva, and Aplecta nehulosa. Among the Georaetrae 

 were Emmelesia decolorata (near Ongar), Larentia didymata, 

 Pericallia syringaria (although small), and P.pustidata {bajidaria). 



Among larvse I did not do much ; being only a temporary 

 resident, I found it difficult to devote the time and space for 

 their occasional feeding. However, I noticed several worth 

 mentioning, especially towards Ongar ; in a small wood I found 

 three Notodonta cliaonia, two N. trimacida (dodonea), and a few 

 Euchelia jacobece, although the latter I observe, in a recently 

 published guide to the Forest, is mentioned as scarce. 



During my rambles in the daytime I noticed a fair number of 

 species belonging to the Diurni, but could not help remarking that 

 many of them were very restricted in locality. Argynnis eiiphrosyne 

 I found plentiful in two places, but away from those I did not see 

 it; the same may be said of A. selene. Lycana argiolus, at the 

 north side of Epping Thicks, where the holly is very prolific, was 

 occasionally to be met with ; and also Pararge megcera, but 

 sparsely. In the low-lying districts Nisoniades tages and 

 Syrichthus alveolus were plentiful ; but beyond one Colias edusa I 

 saw scarcely anything but the common whites. Thecla quercus 

 larvse, although plentiful at oak near Theydon, did not appear in 

 any numbers on the wing; and of T. betulce I found a great 

 difficulty in obtaining a few larvse ; but as I hear that it is 

 sometimes plentiful, I conclude that this is a year of a scarcity. 



The foregoing, although not exhaustive, will therefore show 

 that species generally could not be considered as very plentiful, 

 yet there was sufficient to repay a diligent collector ; and, 

 properly worked bj' anyone living in the neighbourhood, I feel 

 sure that a splendid nucleus for a good collection might be 

 obtained from the Forest alone ; and, doubtless, through want of 

 a better knowledge of the localities, I failed to get many of the 

 good things which it contains.
