showing some sign of life, hoih empty cocoons and those containing 

 living saw rty larvae were taken. The extent of the area infested by this 

 insect was shown by the failure to find a single tamarack tree in this park, 

 on liigh or low ground, under which, covered by the nuss, were not some 

 of the caterpillars in their cocoons. To be sure, the park is not very 

 large; nevertheless, it shows something of the distribution of the insect. 

 Other considerable areas east and north of the park show a like distri- 

 bution. 



At the lime of arrival in the park, July 20th, the saw-tly larvie were ail 

 mature. A few days afterward they had disappeared. On going through 

 the woods and over the swamps one could find thousands of dead larvae, 

 drowned in little pools of water under the trees. Brook trout ( Salvelinus 

 /oiitina/is, Mitch.) caught in a small brook which runs through one corner 

 of the park, always looked very pluin[\ and upon examination their 

 stomachs proved to be gorged with saw-tly larvae. 



Many cocoons were collected, and by next year it should be known 

 whether many or any species of parasites destructive to this pest are at 

 work. 



I WKNTY-SKCONI) ANNUAL MKKTING OF THE AMERICAN 

 ASSOCIATION OF ECONO.MIC ENTOMOLOGISTS. 

 The twenty-second annual n>eeting of liie American Association of 

 Economic Entomologists was held at the Harvard Medical School (Brook- 

 line). Boston, Mass., December 2S and 29, 1909. The first session was 

 called to order by President W. E. Britton, of New Haven, Conn., who 

 presided throughout the meeting, and who delivered the aimual address 

 on, " The Official Entomologist and the Farmer." The programme was 

 crOwdid with papers which were of great economic importance to the 

 Entomologist and the Agriculturist, although a few were more technical in 

 character, and dealt with some of the fundamental principles of scientific 

 investigation of entomological matters. A discussion of different methods 

 used in research work was of particular interest, as was also the reports 

 of ih^ |)rogress that is being made in the field and parasite work in New 

 England, for the purpose of controlling the Gypsy and Ikown-tail mollis. 

 A report by Dr. W. P. Headden, of Colorado, concerning the injury 

 to fruit trees caused by arsenical spraying, and the discussions that fol- 

 lowed, brought out many new ideas on this important subject. .\n
