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 ineludes 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. .

OBSERVATIONS ON FOREST AND SHADE TREE INSECTS IN NEW 
YORK STATE. 
By E. P. Fett, 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 Karner, only 7 miles from Albany. This summer there 
was a very large deposition of eggs, and by July 27 it was easy to find 
entire shoots defoliated, and none of the larve were more than one- 
third grown. The scrub oaks (Quercus prinoides and Q. ilicifalia) are 
likely to suffer severely before the end of the summer, as is not infre- 
quently the case. The web nests of Cacwia argyrospila Walk. were 
not uncommon on the same oaks, the moths emerging at intervals 
during the greater part of July and in early August. 
Systematic collecting at intervals of ten to fifteen days throughout 
the season has been practiced at Karner, where there is an admirable 
growth of scrub oaks and small hard pines (Pinus rigida). A portion 
of the results are given at this time. 
The two large Buprestids, Chalcophora virginiensis Drury and C. 
liberta 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 they are not included in this account. as they
