THE CANADIAN ENTOMOLOGIST. 267 



writings, is questionable at the present time. No cheap process known 

 to the writer gives good results in shaded figures. These figures give 

 promise of something better in the near future. If it were not, however, 

 for this hopeful outlook, it would be well to return to wood-engraving. 

 Entomologists were urged to make their drawings with extreme care and 

 to adapt them to a particular process, and not to rest satisfied with inferior 

 reproduction. The paper was discussed by Messrs. Osborn,Weed, Smith, 

 Hopkins, Gillette, Forbes and Howard. 



Mr. Gillette read a paper on " The Arsenites and Arsenical Mixtures 

 as Insecticides." The article comprised a general summary, historical 

 and critical, of the use of these substances in their different combinations. 

 The paper was discussed briefly by Messrs. Beal, Wood and Galloway, 

 all of whom were present at the meeting, although not members of the 

 Association. 



Upon invitation, Mr. B. T. Galloway, Chief of the Division of Vege- 

 table Pathology of the U. S. Department of Agriculture, gave a short 

 account of some recent work done in his division upon a bacterial disease 

 of melons and other cucurbits, which had been found to be largely dis- 

 seminated by the agency of insects, particularly of Diabrotica vittata 

 and D. 12-pwutata. Messrs. Webster, Smith and Garman had seen the 

 same disease in their respective localities. 



At the third session, held in the afternoon of August 15, an amend- 

 ment to the constitution was adopted levying annual dues of fifty cents 

 upon each member of the Association, and a resolution was passed 

 authorizing the publication of the whole proceedings in Insect Life, and 

 the sending of an abstract to the Canadian Entomologist. 



Messrs. Osborn, Webster and Weed were appointed a committee on 

 nomination of officers. 



Mr. Hopkins read a paper on " Destructive Scolytidas and Their Im- 

 ported Enemy." He gave a summary of the damage done by bark-boring 

 bettles in West Virginia and other portions of the country, and his in- 

 vestigation of this damage in the former State. He further described his 

 trip to Germany during 1892, and the collection of about 1,000 specimens 

 of Clerusformicariits, which he brought alive to this country. He de- 

 scribed the placing of the insects and their over-wintering. Up to the 

 time of presentation of the paper, no means of ascertaining to what ex 

 tent the insects have multiplied had been found.
