as in directions so often published. Tliird, if the caterpillars have 

 been permitted to feed to maturity upon the trees, and tliereafterto 

 enter the ground immediatel}'^ beneath for their transformation, the 

 soil under the trees to the depth of from four to six inches should 

 be thoroughly worked over so as to crush the tender pupte. 



Either one of the above measures, if properly used, will be 

 effectual in arresting the attack. If all are employed, immediate 

 success would be insured. 



The Apple-Leaf Bucculatrix. 



Through Dr. Sturtevant, of the IST. Y. Agricultural Experiment 

 Station, a communication was received from Mr. Malcom Little, of 

 Malcom, Seneca county, N. Y., stating that the apple orchards in 

 that vicinity were infested upon the branches and the fruit with 

 objects such as sent upon some twigs. They had not been seen 

 before, and it was asked what they were, and if they would probably 

 prove injurious. Answer to the following effect was returned : 



The twigs received were thickly covered on one side with the 

 cocoons of the apple-leaf Bucculatrix — Bucculatrix pomifoliella 

 Clemens. A piece of twig an inch and a quarter in length, and 

 one-eighth of an inch in diameter, had upon it thirty-three of the 

 cocoons. From tiie small size and the general appearance of the 

 cocoons they are often mistaken for insect eggs. They are white, 

 about one-fourth of an inch long, as thick as an ordinary pin, and 

 show upon their exposed surface iivfe or six prominent longitudinal 

 ribs. 



The insect is an injurious one. Where it abounds, the cater- 

 pillars consume such an amount of the foliage as seriously to inter- 

 fere with the production of the fruit. It displays a remarkable 

 facility for increase, ^nd every proper means sliould, therefore, 

 immediately upon its discovery, be resorted to, that its spread may 

 be arrested. 



The parent is a small moth belonging to the Tineidm — that divis- 

 ion of the Lepidoptera that embraces the smallest species of the 

 order. There are two annual broods of the insect. The cocoons 

 Bent to me are of each brood. Some of them were spun in July, 

 and have given out the insect, leaving only the empty pupa-case 

 within the cocoon. The moths that emerged from them laid eggs 

 from which caterpillars were hatched, which might have been 

 observed feeding upon the leaves in September, if attention had 

 been given to the eaten foliage. The caterpillars make their 

 cocoons during October, and upon opening those that are the 

 freshest-looking and unbroken, their pupse may be found, which 

 are destined, if not meanwhile destroyed through parasitic or 

 atmospheric agency, to remain in that state tliroughout the winter, 

 and to give out the moth in the month of May next.
