It has also been reported from Massachusetts, Connecticut and New 

 York. The fly appears in July ; with a sharp ovipositor it inserts 

 its eggs into the apple. It frequently attacks apples which have 

 been previously perforated by the codling moth. It is said to prefer 

 thin skinned summer fruit to the winter varieties. There is only one 

 brood of this insect ; it enters the ground for transformation. If this 

 enemy should become troublesome to the fruit-raiser it would be a 

 dangerous one to deal with ; but it seems that being a fly the whole 

 tribe is not very abundant every season. As I have not yet observed 

 this pest, I do not know what remedy. 



The Twig Girdler {Oncideres cingulatus) . The young larva bur- 

 rows into the wood and feeds on it ; here it transforms to a pupa. 

 The twig having been girdled by the female will easily break off 

 with the fall winds. The pupa winters in the fallen limb on the 

 ground ; the beetle appears the next season. All the fallen branches 

 should be collected in the early spring and destroyed by fire. There 

 are a good man}- other species hidden away in fallen branches and the 

 orchaidist should be very careful in collecting them every spring and 

 burning them up as a rule. 



The Pear-tree Slug {Selandria cerasi). This is a saw-fly, having 

 3l small ovipositor in a shape of a saw. With this instrument the 

 female cuts slits in the leaves and inserts an egg in everj^ slit. The 

 slugs are covered with a bluish slime, which is disgusting to behold ; 

 it has a strong repugnant smell, the}' eat holes in the leaves. When 

 full grown it appears in a clean dress, descends to the ground and 

 transforms and hatches in about three weeks. In the middle of 

 July the new females deposit a new batch of eggs. 



Remedy. Hellebore, in powder, mixed with water, in propor- 

 tion of one ounce to two gallons of water, applied to the foliage with 

 ii syringe, will kill the slug. On small trees air-slacked lime dusted 

 on the foliage will be of good effect. 



The Plum Curculio {Conotrachelus nenuphar). The larva bur- 

 rows into the flesh and feeds around the stone ; when full 

 grown, in three to four weeks, the larva enters the ground and 

 transforms. It remains over winter in the beetle state, and comes 

 forth again next spring. 



Remedy. The beetle can be easily destroyed by shaking the tree and 

 spreading a cloth under it ; they will fall, and may then be destroyed. 

 The tree should be jarred when in blossom, and to be continued 

 daily, mornings and evenings till they become scarce. It is very
