counties infested which I have reported upon and in addition, as you 

 will note from the chart, a few counties to the north. He also refers 

 to one isolated example in 1895 from the extreme northern part of the 

 State near Lake Vermilion. This latter reference, as far as I can 

 make out, is something in the nature of a rumor. I can find no speci- 

 mens in the collection substantiating the report. The chinch bug- is 

 not known in the Red River Valley along the western border, nor is it 

 known north of the imaginary line shown in the map, with the possible 

 exception above noted. It occurred to me that these conditions might 

 interest entomologists, particularly as maps have been published and 

 republished indicating in a general way that the chinch bug is found 

 oyer the entire State. It must be admitted that a few sections might 

 have chinch bugs which arc not reported; nevertheless the close simi- 

 larity in the findings of the late Dr. Lugger and the present entomol- 

 ogist would seem to place the matter of its distribution beyond ques- 

 tion. The year has been unfavorable for this pest, the summer having 

 been a decidedly wet one. I might say that much of the blame of 

 injury caused by the Hessian fly, a pest even now of almost universal 

 occurrence in Minnesota, has this summer been laid at the door of the 

 chinch bug, with which farmers are much more familiar than they are 

 with the former insect. 



At the conclusion of this paper Mr. Burgess inquired of Mr. Wash- 

 burn if the chinch bug fungus was being used in Minnesota to any 

 extent at the present time. 



Mr. Washburn replied that it had been almost entirely abandoned. 

 It had not been found practicable. 



The meeting then adjourned, to reassemble at 2 p. m. - 



AFTERNOON SESSION, FRIDAY, DECEMBER 26, 1902, 2 P. M. 



The meeting was called to order by the president, who, after calling- 

 Mr. Osborn to the chair, presented a paper on the following subject: 



OBSERVATIONS ON THE GRAPEVINE ROOT-WORM. 



By E. P. Felt, Albany, N Y. 

 [Withdrawn for publication elsewhere.] 



Mr. Burgess remarked that the life history of the grapevine root- 

 worm had been worked out by Messrs. Webster and Mally several 

 years ago, and that this had been published along with results of their 

 experiments in its control. A year ago he had carried on a few 

 experiments under Mr. Webster's direction for spraying for this 

 insect with arsenate of lead, and, although the results were not con
