Mr. AsliDiead said that it was very gratifying that something was 

 being done with the enrcnlio problem, and he recounted some of the 

 diffictilties which attended the attemi^t toward its control. He men- 

 tioned its parasite {SigaJphus curcuJionis, Fitch) and snggested that 

 if it did not already' occur in Geors^ia it be introduced. 



Mr. Bruner spoke of the great A^ariety 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 abtindant this season. He 

 also spoke of the interesting relations existing between insects and 

 fungi, as referred to in the i^aper comparing the cure alio 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 Avotild 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 wotild have been i)ossible to 

 have listed many species of Hymenoptera, Diptera, Lepidoptera, etc., 

 but it was not thotight advisable becatise tlie specimens were in a 

 badly mutilated condition. 



3Ir. 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 Xorth the higher x:)rice 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 wotild add much 

 to the value of this paper if it were accomj)anied by a complete list of 

 the insects taken in the jarring operation, and tlie writers were 

 requested to furnish the list for publication. 



Mr. Ball then presented the following paper:
