184 THE CANADIAN ENTOMOLOGIST. 



Mr. Westcott very kindly promised to give his attention to this matter 

 at an early date. We shall hail the advent of this list with much satis- 

 faction ; it is a work greatly needed, and coming from the hands of one 

 who is in every way well fitted to do it justice, we feel sure that it will 

 command general assent. 



The next subject of discussion was on certain offensive names which 

 have been proposed for insects, in which most of the members took part. 

 The following resolution was unanimously adopted : — 



Resolved, that in view of the fact that certain names have of late been 

 proposed for insects which are offensive and unwarrantable, that the 

 Committee on Nomenclature be requested to present at the meeting next 

 year a list of such names as should be ignored, so that the club may take 

 action in reference to them. 



Some explanations were then offered in regard to a valuable discovery 

 lately made by Mr. George Dimmock, of Springfield Mass., of a ready 

 method of removing the scales from the wings of Lepidopterous insects, 

 so as to display the vein structure. Mr. Dimmock had kindly shown the 

 admirable working of his process to a number of Entomologists at his 

 room the evening previous, when all present were struck with the great 

 practical value of the discovery. After full explanations to those present 

 who had not seen the working of the process, it was resolved, " That the 

 thanks of the members of the Entomological Club be given to Mr. Dim- 

 mock for his valuable discovery in reference to a ready method of 

 denuding the wings of insects." 



This process of Mr. Dimmock's formed the subject of a paper read 



before the American Association, and which will be published, we believe, 



in an early number of Psyche. It may thus be briefly explained : All the 



materials necessary are a little alcohol, a saturated aqueous solution of 



chloride of lime, a phial of pure muriatic acid and another of sulphuric 



acid. The wings are first moistened with alcohol, then transferred to the 



solution of chloride of lime, to which a little of the sulphuric acid has 



been added. After immersion for a few moments, the coloring matter of 



the scales rapidly disappears. This result may be hastened by taking the 



wings out of the chloride of lime solution and immersing for a moment 



n the muriatic acid, diluted with twice its weight of water, and then 



returning them again to the former solution. This alternation may be 



repeated as often as required. By this means any quantity of wings of 



Lepidoptera may be safely and entirely denuded with little or no trouble.
