the larva? of Ephestia knehniella ZelL, and Phanerotoma tihialis 

 Hald. from pecan nuts badly infested with Balaniniis caryce Horn. 



To Dr. L. O. Howard and his assistants the writers are indebted 

 for the determination of a considerable number of the species above 

 mentioned. 



Mr. Slingerland called attention to the fact that prepared arsenate 

 of lead in wooden buckets dried and caked badly. He thought it 

 was UHich better to ])urchase in tin. 



Various speakers comphiined of its eating through the tin and con- 

 sequently they preferred the wood, but the members were evidently 

 divided as to Avhich was better. 



Mv. Quaintance asked what the effect of arsenate of lead was on 

 peach and plum. 



Mr. Smith said that it could be used two or three times on peach 

 at the rate of 1 pound to !25 gallons without apparent injury. 



Mr. Slingerland questioned the advisability of the home-made 

 arsenate of lead, because the nuiterials were often adulterated. 

 Messrs. Burgess and Sanderson both believed that the arsenate of 

 soda was often adulterated and unreliable in strength. Mr. Fernald 

 preferred to make his own, but felt it necessary to be very particular 

 from what source the arsenate of soda was obtained. 



The question of the advisability of using trade names in publica- 

 tion was brought up, and a lively discussion, participated in by almost 

 all of the members, indicated that the general feeling was that the 

 exact truth should be told about materials sold under trade names, 

 referring to them bv these names in the publications. In some 

 rases, however, this was iuipossible on account of the official censor- 

 ship. Some members, however, believed that trade names should not 

 be used in publication. 



The question arose as to whether it was desirable to publish the 

 names of people on whose pi"operty exjoeriments are made or whose 

 premises are infested with certain insects. Mr. (xillette believed 

 that this should rest in each case with the party concerned. If the 

 owner of the property wished his name mentioned, this sliould be 

 done, but otherwise not. Mr. Burgess agreed with this ^■iew. In 

 Ohio there had been a prejudice against firms who fumigated their 

 trees. A photograph of a fumigating house of one nurseryman was 

 secured, but the owner was consulted as to whether he desired to have 

 his name mentioned before any steps were taken concerning its 

 publication. 



Mr. Slingerland asked if eutomologists should be expected to test 

 all the nostrums that are put on the market.
