from the attacks of the maggots of C. sulcatus as 

 soon as the beetles appear ; sieves should be held at 

 night under the branches and leaves, when, by- 

 shaking them, the beetles will readily fall into the 

 sieves, but as they drop down when approached, this 

 operation must be proceeded with gently and quietly ; 

 multitudes may be thus collected, both in and out of 

 doors, and if the person who carries the light has a 

 pail or jug of water, the sieves can be emptied into 

 them, as occasion may require ; but when the beetles 

 are eventually destroyed, boiling, not warm water, 

 must be used, as the hardness of their horny cover- 

 ing will resist a considerable degree of heat. When 

 the larvse are ascertained to reside at the base of a 

 wall, salt might be freely sprinkled, which will kill 

 them as readily as it will the maggots in nuts ; 

 strong infusions of tobacco-water, aloes, and quassia, 

 are also recommended. Where the blood of animals 

 can be obtained, it might be beneficially applied, as 

 it would coagulate over the tender larvae and pupae, 

 and set them fast in the earth. [Gard. Chron.

Thrips. — This minute insect belongs to the same 

 genus as that {Thrips physapus) which tickles the 

 face so intolerably during the sultry weather of our 

 summers. The thrips sometimes attack the young 

 shoots of vines growing in the open air, especially 

 those of weak vines, or vines newly planted. If
