THE CANADIAN ENTOMOLOGIST. 177 



Extinguisher, charged in the usual way, with the addition of a little crude 

 carbolic acid, in the proportion of about one large spoonful to six gallons 

 of water. By means of the Extinguisher she was able to reach even large 

 trees, the cost being about 20 cents per tree. The remedy should be 

 applied before the insects become too old, otherwise a stronger preparation 

 of carbolic acid was necessary, and in consequence the trees might pos- 

 sibly suffer somewhat. 



Mr. Thos. Bassnett, of Jacksonville, Florida, had listened to the 

 admirable account with very great interest, inasmuch as in the South the 

 culture of the Orange tree, in which he was largely interested, was seri- 

 ously threatened with extermination by the ravages of a bark-louse similar 

 to that described by Miss Smith, and he was glad to hear that a remedy 

 could be so successfully applied. 



Prof. C, V. Riley, of Washington, D. C, spoke, thanking the lady for 

 bringing this subject before the meeting, and complimenting her on the 

 discoveries she had effected. He fully corroborated the statements made 

 as to the extent of damage caused by bark-lice, especially those affecting 

 the Orange in the South. He strongly advocated the use of the 

 *' Extinguisher" in similar cases, but recommended that kerosene should 

 be tried instead of carbolic acid ; it would, he thought, be found of less 

 injury to the trees, and would destroy the insect for some time after the 

 formation of the scale, which the carbolic acid would not do. It should 

 not be applied in excess ; the ordinary proportion should be about one 

 part kerosene to twenty of water. 



The whole topic was very fruitful of discussion, and Miss Smith was 

 much thanked for her paper and for the drawings and microscopical pre- 

 parations that accompanied it. 



On motion of Prof. Riley, seconded by Mr. Reed, a resolution was 

 carried that a committee be appointed to prepare a report and submit to 

 the next session of the Club, in regard to the quorum of members neces- 

 sary to transact business. 



The Chairman appointed the mover and seconder and Prof. A. G. 

 Wetherby as the committee. 



Prof. Riley gave a brief abstract of some of the Entomological papers 

 he proposed to read to the Association.
