eases. Upon being disturbed these insects fall to the ground as though dead, 

 but become active on reaching the grass under the tree. 



- Their feeding habit closely resembles that of the Rose beetle, only they do 

 not appear to attack the fruit save in rare instances. They seldom fly and 

 when they do their flight is only for a few feet, from one limb of the tree to 

 the other. 



But comparatively few of these insects were left on the above date as the 

 manager states that they appear about the middle of June and leave about 

 the middle or latter part of July. 



Specimens sent to Dr. L. O. Howard were identified by Mr. Schwarz as 

 Anomala marginata Fabr. They are very like the common "June bug" found 

 during the summer season on blackberry bushes, feeding on the fruit, only they 

 are about half the size. The male of this species seems to have the peculiar 

 habit of hanging on to the female, clasping the posterior portion of her ab- 

 domen with his anterior pair of legs when not feeding. The male is somewhat 

 smaller than the female, abdomen darker, thoracic segment more narrow and 

 deeper green. 



The examination of this orchard was made after two o'clock in the afternoon. 

 The manager states that these insects have been doing some little damage for 

 the past two or three years but had been much worse during the present sea- 

 son than ever before. An examination of the surrounding orchards in this 

 locality was not made at that time but no other similar complaints were re- 

 ceived at this office.

Insect Work on the Shade and Ornamental Trees in Brooklyn for 1909. — 

 This year was the first one in the history of Brooklyn that the insect enemies 

 of its shade and ornamental trees were controlled with a marked degree of 

 success. This is due partly to the egg-destroying work of the previous years, 

 partly to the additional eciuipment of gas spraying machines and the early 

 spraying, but more than anything else to the better grades of spraying ma- 

 terial employed. For many years past the spraying done in this citj' proved 

 ineffective. The futile results were of common note, but the cause was un- 

 known. Last year a few chemical tests with the arsenate of lead in use told 

 the whole story. This year five other brands of lead, selected according to the 

 tests recorded in Bulletin 214 of the N. J. Agric. Experiment Station, were 

 employed and all proved efficient. Twenty-three thousand pounds of lead were, 

 used and over forty thousand trees were sprayed. The Tussock Moth, our 

 worst enemy, and Datana ministra were the most numerous caterpillars. 

 The elm-leaf beetle was very abundant, but was readily subdued by the early 

 spraying and later by the oil emulsions applied at the base of the trees during 

 the period of pupation. The scurfy and oyster shell scales were thickly in- 

 festing five thousand elms, and an application of whale oil soap at the rate of 

 one pound to six gallons of water (suggested by Prof. John B. Smith) proved 

 very effective. The Ailanthus and Cynthia moths and the bag-worm, though 

 very numerous last season, were hardly seen this year. The few pupie of 

 these species all seemed to have been parasitized. The new pests which are 

 becoming formidable are the linden borer {Baperda vestita) on the European 

 lindens and the hickory bark borer (Scolyttis quadrispinosus) on all species 

 of hickories. The former is as yet not very serious and the injections of
