trees with whale-oil soap diluted with water. Frequent 

 drenchings, natural as well as artificial, are extremely nseful 

 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 Litliocolletis geminateUa. 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 (-14 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 chrj'salis within its mine. When dis- 

 turbed it crawls rapidly out of its domicile and hangs sus- 

 pended by a thread, unwittingly open to the attacks of the 

 smaller birds, to whom all these minute leaf-i-olling and 

 mining caterpillars are a dainty tit bit. Indeed, were it not 

 for the Ivind 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, Avhile the 

 moths first appeared in Salem on the 19th of August, flying 

 in doors during the niS-ht, 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 Biicculatrix. — Closely rcscmljling in its general 

 appearance the preceding moth, this beautiful form is much 

 paler, almost whitish, with j^ellowish 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
