AN IMPROVED COLLECTING BOTTLE. 



By C. N. Aixslie, 



U. S. Department of Agriculture, Bureau of Entomology, Cereal 



and Forage Insect Investigations. 



In common with many other entomologists, I have been greatly 

 annoyed by the condensing of the moisture on the inside of my 

 collecting bottle. I notice that some entomologists make a hole 

 in the cork and place a lump of cyanide therein, but in my experi- 

 ence it is only a matter of a few days until the cork becomes damp 

 and sticky and unfit for use, especially in rainy weather. 



The writer has recently adopted the plan of sinking a 9 x 36 mm. 

 shell vial in the cork, with the mouth of the vial opening into a 

 larger bottle or tube, whichever may be used. If these 9 x 36 mm. 

 vials are too long they may be cut off so that the opening will be 

 flush wath the surface of the cork, although I prefer to have them
