able for such work. As is well known, the butterflies delight in 
the bright sunshine, and, as the day was dull, few species were 
seen. Altogether eight different kinds were observed, but none of 
these were plentiful. The first specimens of the season of the Little 
Wood-satyr, Neonympha eurytus, Fab., were seen flitting about in 
the woods. On account: of 
the weather, therefore, those 
seeking insects confined 
most of their attention to 
the collection of lepidopter- 
ous larve, and many cater- 
pillars of some of our noc- 
tuid moths were found be- 
neath pieces of board, chips, 
etc.,on the ground. Two. 
different species of arctian 
larve, viz., Apantesis virgo,. 
L., and A. parthenice, 
Kirby, were collected. On 
several wild cherry trees, 
tents containing numerous 
specimens of the American 
Tent Caterpillar were ob- 
served. This injurious in- 
sect of orchard and forest, 
American or Apple-tree Tent Caterpillar: : 
a, tent; 0, caterpillar; c, egg mass it is to be regretted, seems 
Se eiES Gf eeceon. to be on the increase again. 
Everybody can do something to control it by cutting off the tents 
whenever seen and trampling on them, thus destroying every 
time a colony of upwards of two hundred caterpillars. Much of 
the foliage of some Silver-leaved Maples was conspicuously dis- 
figured by being covered with the galls of the Maple-leaf Gall-mite, 
Phyptoptus quadripes. This is a very small mite which causes the 
elongated galls which sometimes cover the whole upper surface of 
the leaves. It has been particularly abundant this year on orna- 
mental maples. Unfortunately, nothing in the way of a remedy 
can be suggested for this pest other than spraying with the lime 
and sulphur mixture before the buds burst, as is done against the 
Pear-leaf Blister-mite ; for it probably hibernates in the same way 
in the scales of the buds. A.G.
