Mr. Ashmead said that it was very gratifying that something was 
being done with the cureulio problem, and he recounted some of the 
difficulties which attended the attempt toward its control. He men- 
tioned its parasite (Sigalphus curculionis, Fitch) and suggested that 
if it did not already occur in Georgia it be introduced. 
Mr. Bruner spoke of the great variety of insects caught, and expressed 
a desire to see the complete list. 
Mr. Hopkins suggested that many of the insects would fly away in 
the process of jarring, and for that reason all the insects that might 
occur on the trees would not be taken. He thought that most of the 
Lachnosterna might thus escape, but that a better explanation of the 
scarcity of these insects in the catchings was probably in the fact that 
for some reason they were not generally abundant this season. He 
also spoke of the interesting relations existing between insects and 
fungi, as referred to in the paper comparing the curculio and the leaf- 
footed bugs in their relation to the brown-rot fungus with the mutual 
dependence between certain Scolytids and the fungus with which they 
are closely associated, in causing the death and rapid decay of forest 
trees. 
Mr. Scott said that the operation was conducted during the early 
morning hours when the insects of nearly all sorts were in a semi- 
dormant condition, and on this account many species were taken 
which would not have been later in the day. The leaf-footed bugs 
might be cited as examples, for, though captured in numbers, they 
are among the most active insects. It would have been possible to 
have listed many species of Hymenoptera, Diptera, Lepidoptera, ete., 
but it was not thought advisable because the specimens were in a 
badly mutilated condition. 
Mr. Galloway said that the agency of insects in disseminating brown 
rot was a point that should be taken into account in the treatment of 
this disease. 
Mr. Howard thought that while cheap labor made the jarring 
method practicable in Georgia, in the North the higher price for labor 
might make it too expensive. 
Mr. Ehrhorn said that this pest did not exist in California and that 
the fruit growers there were in great fear of its introduction. 
_ Mr. Gillette said that so far as he knew it did not occur in Colorado, 
and that they also entertained fears of its introduction. 
Mr. Bruner, Mr. Howard, and others, thought it would add much 
to the value of this paper if it were accompanied by a complete list of 
the insects taken in the jarring operation, and the writers were 
requested to furnish the list for publication. 
Mr. Ball then presented the following paper:
