trees with whale-oil soap diluted with water. Frequent 
drenchings, natural as well as artificial, are extremely useful 
in ridding trees of caterpillars, and turning the hose on 
infested trees is an excellent remedy against all sorts of 
caterpillars, particularly the bud worm and Palmer worm. 
The Twin Spotted Leaf Miner. —Another of that exquisite 
family, the Tineids, often infests the apple in immense num¬ 
bers, mining the leaves, leaving a serpentine blotch to mark 
the site of its gallery. It bears the sesquipedalian name 
of Lithocolletis geminatellu. It is figured in all its stages on 
plate 8 of the “Guide to the Study of Insects.” The little 
caterpillar is slightly over a line in length (T4 inch), of a 
pale livid reddish hue with a black head, the segment behind 
the head being also blackish. When it becomes fully fed it 
transforms into a chrysalis within its mine. When dis¬ 
turbed it crawls rapidly out of its domicile and hangs sus¬ 
pended b}’’ a thread, unwittingly open to the attacks of the 
smaller birds, to whom all these minute leaf-rolling and 
mining caterpillars are a dainty tit bit. Indeed, were it not 
for the kind offices of these feathered friends of ours, these 
tiny thieves would leave no food for their giant friends, 
the canker worms and tent caterpillars. The worms occur 
throughout the last of summer and early autumn, while the 
moths first appeared in Salem on the 19th of August, Itying 
in doors during the night, attracted by the light. It is a 
beautiful creature, with long, narrow, delicate wings fringed 
with long lashes, with a yellowish tuft of hairs on the top of 
the head. It is of a dark slate gray color, with an eye-like 
spot at the end of the fore wings, pupilled with black, like 
the “eye” in a peacock’s tail. 
The Apple Bucculatrix. — Closely resembling in its general 
appearance the preceding moth, this beautiful form is much 
paler, almost whitish, with yellowish scales, and a curved 
black line curving around to the apex of the wing, ending 
in an eye-like spot on the outer edge ; in the middle of the
