THE MACRO-LEPIDOPTERA OF EPPING FOREST. 153 
only allow an enumeration of a part of the number. Among the 
species most in repute may be mentioned Phorodesma bajularia, 
Angerona prunaria, Geometra papilionaria, and Pericallia syrin- 
garia. The first-named may be taken both at Chingford and the 
Hagger Lane Forest, and sometimes occurs in large numbers 
throughout the month. The graceful flight of A. prunaria may 
be witnessed almost everywhere in the Forest at dusk, especially 
in that part of it abutting on Chingford Station, and as several 
dozen may be taken on almost any fine evening, a varied series 
may be had without much difficulty. G. papilionaria is taken, 
although sparingly, wherever the birch abounds, and P. syringaria 
at Walthamstow and High Beech. Of ubiquitous occurrence 
may be mentioned Cabera exanthemaria, Metrocampa marga- 
ritaria, Hemithea thymiaria, C. pusaria, Acidalia aversata, Me- 
lanthia ocellata, Coremia ferrugata, Melanippe subtristata, A. 
bisetata, Cidaria fulvata, and many varied forms of Ypsipetes 
elutata, both of the latter insects often coming to sugar. Hedges 
around Walthamstow near which the ragged robin grows will 
furnish us with Hmmelesia decolorata, and wherever the common 
chervil grows there will be found Larentia didymata. M. rubi- 
ginata, Ephyra punctaria and Ligdia adustata are to be found 
everywhere, and Timandra amataria may be secured in most 
parts of the Forest. The rapid flight of Ourapteryx sambucata 
will be seen true to its time, viz., about the 10th July, and is one 
of the best time-markers among the Geometre. Camptogramma 
bilineata will furnish the young beginner with a varied series, 
from light yellow to dark brown, and Abraxas grossulariata, 
common though it is, will generally repay the earnest worker by 
revealing many variations of marking and colour. Pseudo- 
terpna cytisaria is now on the move, and the beginner will find 
how difficult it will be to get a satisfactory series, and will 
remember next year that the best way to get it in good condition 
is to collect the larva, which being of a light green colour, with 
a purple marking along the spiracles, forms a pretty object when 
feeding on the Genista anglica, which it does early in June, 
wherever that plant is found growing in the Forest. Among the 
thorns I may enumerate Selenia illunaria, Crocallis elinguaria, 
Ennomos angularia (Monks Wood, plentiful.) Many more may be 
brought into view by beating the herbage and various undergrowth. 
A still longer list of Noctuse may be found, among which many
