go REPORT ON THE LICHENS OF EPPING FOREST. 
When the moth is at rest it assumes a very remarkable position 
in which it strongly resembles a dead and dry leaf still attached 
to the stem. The front legs are stretched out straight in front 
of the head at a right angle to the axis of the body, the second 
pair of legs being pressed close to the body, whilst the last 
pair just hold to the support, almost, or quite, covered by the 
tips of the fore wings which just touch beyond the body, the 
moth appearing to be clinging to its support by the front legs 
and wings only. It falls to the ground when touched. 
REPORT ON THE LICHENS OF EPPING 
FOREST (SECOND PAPER.)

T N our earlier paper on this subject, Essex Naturalist, 
A vol. xvi., pp 136-45, we adduced evidence to show that 
the view held by the Rev. J. M. Crombie in 1883, as to the 
condition of the Lichen-flora of Epping Forest was, happily, 
not borne out by our experience. Our optimism has been 
fully justified by two years’ further experience. Crombie’s 
list of 85 forms, which he presumed to be the total number 
of lichens then existing in the Forest, has been by far exceeded, 
and our record to date comprises 109 fully-determined forms 
which our researches have proved to be still extant within 
the limits of the Epping Forest district. Moreover, our present 
total includes not only a number of forms, in flourishing con¬ 
dition, which Crombie variously described as “ evidently ex¬ 
tinct,” “ very rare,” or “ sterile and sparing,” or which he himself 
had not observed, but also some really rare forms which have 
not hitherto been recorded by any observer from this locality 
or from the County. 1 
In the light of these facts, although it would seem probable 
that our list is now nearing the actual total of the present-day 
lichen-flora of the Forest district, it would be folly to insist 
too strongly upon this, as new discoveries are always possible 
in the case of such inconspicuous plants. As an instance of 
this, we need only cite the case of Gongylia viridis which, known 
x At the same time it should be noted that of our total number of forms several occur 
only in small quantity and in scattered localities.
