Mr. Cook said he had found mallem about as attractive as could be 

 for cutworms ; they will take it in preference to anything else. 



Mr. Beckwith asked about the pupating habit of the cankerworm. 

 He has seen the statement that they pupate in a cocoon ; the specimens 

 bred by him all formed naked pupae. 



Mr. Kiley said it depends on the species of cankerworm. Paleacrita 

 vernata^ if he recollects aright, has no cocoon, or a very fragile one; but 

 the autumnal species {Ayiisopferyx pometeria) hskS quite a tough cocoon. 

 For the former, fall plowing is a good remedy. 



Mr. Harvey confirmed the statement that the fall species forms a 

 cocoon, and stated that it is rather a thin covering of silk covered with 

 grains of sand or earth. In this connection he remembered that some 

 of the orchardists in his State claim that they prevent injury from the 

 borers by rubbing the base of the tree with the hand. 



Mr. Smith said that in his experience *S'. Candida is by no means con- 

 fined to the base of the trees. He finds them in all parts of the trunk 

 of quince, entering apparently from some distance above ground. 



Mr. Eiley thought they very rarely oviposit much above the base, 

 though when they get into the trunk they often bore upward some dis- 

 tance. 



Mr. Cook said that he had taken both Candida and cretata even in 

 the branches. 



Mr. Osborn said that he also finds cretata in the branches. 



Mr. Eiley said this preference of cretata for branches agreed also 

 with his experience. 



Mr. Harvey said that he finds both roundheaded and flatheaded 

 borers at the base of the trees. There has been considerable injury 

 caused during the year on the branches of blackberry by a larva which 

 seems to be that of Tmetocera ocellana. He has found no record of this 

 species attacking blackberry and this habit is apparently new. 



On motion of Mr. Howard it was resolved that the proceedings be 

 published in Insect Life. 



The association then adjourned.
