Special Meeting of July 14, 1911. 

 A special meeting was held in Room 2 of the Bureau of Ento- 

 mology to take action on the death of Mr. D. W. Coquillett. 

 The meeting was called to order by President Webster. Sev- 

 eral of the members present spoke of the character and work 

 of Mr. Coquillett. A committee was appointed, consisting of 

 Messrs. Banks, Currie, and Walton, to prepare a biographical 

 sketch of Mr. Coquillett. The following resolutions were 

 adopted : 



Whereas, the Entomological Society of Washington has lost 

 by death one of its former Presidents, Daniel William Coquil- 

 lett; and 



Whereas, Mr. Coquillett was one of the oldest members of 

 the Society and had, by his painstaking work, particularly in 

 the study of Diptera, done much to advance our knowledge of 

 this group, and published largely in the Proceedings of the 

 Society; and 



Whereas, by reason of the very important work which he 

 accomplished in economic entomology, notably the introduction 

 and perfection of the hydrocyanic-acid gas treatment for the 

 disinfection of citrus and other plants, perhaps the most im- 

 portant means of controlling scale insects known; and for the 

 important part played by him in the colonization and establish- 

 ment, in California, of scale enemies imported by Mr. Koebele, 

 notably the Vedalia cardinaJis: and 



Whereas, his devotion to his work, his earnestness, and his 

 uniformly kind and helpful character had gained him a high 

 place in the esteem of the members of the Society; therefore. 



Be it resolved. That in the death of Mr. Coquillett the So- 

 ciety has suffered a very great loss, and that the field of sys- 

 tematic Diptera has been deprived of one of its most prominent 

 workers; and 



Be it further resolved, That a committee be appointed to 

 prepare a sketch of Mr. Coquillett's life, including a bibli- 

 ography of his writings, for publication in the Proceedings of 

 this Society.
