locomotion and feeding. The insect hibernated within this case, fastened 

 closely to the twig. A few days ago, on awakening from its Avinter 

 sleep, it songht the unfolding buds, and commenced to feed thereon. 

 The case, wliich is slightly curved at its anterior end, is at this time, 

 about one-twelfth of an inch in length. The larvfe will continue, 

 unless destr<'yed, to feed upon the foliage until about the middle < f 

 June, when they complete their growth, transform to the pupa state 

 within the pistol-shaped cases, which will then measure one-fourth of 

 an inch in length, and give out the moth during the month of July.* 



The proper treatment for this insect is arsenical spraying at the time 

 of the opening of the buds, and at intervals thereafter, if required. It 

 has been noticed at length in my F'irst Report on the Instctsof New 

 York. The figure illustrating the insect is herewith given. 



A third insect was found associated with the above, viz., the cater- 

 pillar of the eye-spotted bud-moth. Tmetocera ocellana (Schiff). This 

 destructive caterpillar, which in its early stage eats out the buds of the 

 apple tree and completely destroys them, is causing serious injury, and 

 is apparently annually increasing in the orchards of our State. It may 

 be killed by thorough spraying with Paris green, at the same time as 

 for the case-bearer. 



Mr. Malcom Little, of Malcom, Seneca county, has sent the follow- 

 ing communication, dated April 27th : 



I inclose with this a box containing apple buds with at least two 

 kinds of enemies. One is the aphis and the other a worm entirely 

 new to me. There are empty cocoons on some of the twigs. The 

 worm cuts the bud off in some instances. Will spraying with kerosene 

 emulsion kill the worm ? 



The buds submitted showed the presence of three insects. The apple- 

 tree aphis was quite abundant. The little brown, black-headed cater- 

 pillar of the eye-spotted bud-moth was eating into several of the buds. 

 The short bits of twigs bearing the blossom buds were, in some 

 instances, M'hitened with the little ribbed, ellipsoidal, white cocoons of the 

 apple-leaf Bucculatrix, Hucculatrtx jJornifolieUa Clemens. Most of 

 the cocoons were old ones of last year which had given out the moth 

 and were more or less broken, but a number of them contained the 

 living pupa, as was found by crushing them beneath the finger, which 

 would in a few days have disclosed the winged insect in the orchard 

 for deposit of the eggs of another brood. 



* The larvas ceased feeding in June and fastened themselves to the sides of the box, but did 

 not give out the imago. On examination, the cases were found to contain the dead and 

 shriveled lavae.
