the Victoria Comity History of Essex (marked V.C.H.) and other
sources. The area regarded as Epping Forest is that shown on
the map on Plate 1 of vol. vi. (1892) of the Essex Naturalist.
Very little work appears to have been done in the northern
third of this area and records from that district will be welcome.
It is to be noted that "Walthamstow" in the localities refers
to that part of the Forest between St. Peter's Church and the
Waterworks. Mr. Butler tells me that this used to be a good
collecting locality 30 years ago, and that the nest of Formica rufa
(the Wood Ant) mentioned in the records was the only one he
knew of in the Forest; needless to say it has long since dis-
appeared. Ponds near the "Robin Hood" include the large
bathing pond on Strawberry Hill and several other ponds in the
vicinity. The Roman numeral following certain localities (e.g,
Monk Wood IX.) refers to the month in which the specimen was
captured or observed.
