Mr. Scott suggested that Georgia afforded a splendid field for inves- 

 tigations of this nature, as valuable timber in that State was being 

 rapidly destroyed by the work of insects. He made particular refer- 

 ence to the wholesale destruction of chestnut and oak. 



Mr. Bruner said that he had been connected with growing trees 

 upon forest reserves and that he had seen the destructive work of 

 these forest insects. He said that species of Dendroctonus kill thou- 

 sands of trees in the forests of the Black Hills. He thought the 

 Bureau of Forestry should take up the matter of insects in connection 

 with other work, and he thought the time ripe for the publication of 

 a manual on forest insects. 



Mr. Hopkins said that the species of Dendroctonus referred to was 

 evidently the one he had determined as a new species, from specimens 

 sent to the United States Department of Agriculture from the Black 

 Hills, to which he had given the manuscript name Dendroctonus 

 ponderosa. He also said that it belonged to the division of the genus 

 which includes the most destructive enemies of the pine and was, 

 therefore, doubtless the one to blame for the serious troubles which 

 from time to time during the past three years has been reported from 

 the Black Hills region. 



Mr. Felt followed with his paper entitled : 



OBSERVATIONS ON FOREST AND SHADE TREE INSECTS IN NEW 



YORK STATE. 



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



The season of 1901 has not been specially notable on account of 

 insects depredating on either forest or shade trees. The senatorial 

 oak worm {Anisota senatoria Sm. & Abb. ) is more or less abundant 

 every year at Earner, only 7 miles from Albany. This summer there 

 was a very large deposition of eggs, and by Julj^ 27 it was easy to find 

 entire shoots defoliated, and none of the larvse were more than one- 

 third grown. The scrub oaks (Quercus prinoides and Q. ilicifoUa) are 

 likely to suffer severely before the end of the summer, as is not infre- 

 quently the case. The web nests of CaccEia argyrospila Walk, were 

 not uncommon on the same oaks, the moths emerging at intervals 

 during the greater part of July and in earl}^ August. 



Systematic collecting at intervals of ten to fifteen days throughout 

 the season has been practiced at Earner, where there is an admirable 

 growth of scrub oaks and small hard pines (Pmus rigtda). A portion 

 of the results are given at this time. 



The two large Buprestids, Chalcophora virginiensis Drury and C. 

 liherta Germ., were taken throughout June and in early July, and two 

 of the former species were captured August 9, though not met with 

 on two previous trips. Large numbers of smaller Buprestids were 

 also taken on pine, but thej^ are not included m this account., as they
