Described in 1881 as a Chariclea, and made a new genus 

 ChavKeclea in 1883, both descriptions being by Mr- Grote. I 

 presume this becomes the type of a new genus as well as of the 

 species, notwithstanding the fact that the species was described 

 first.

ON A NEW CYANIDE BOTTLE. 



By L. E. RiCKSECKER. 



Several years ago I invented a new killing-jar, and having 

 thoroughly tested the same, and found it a great improvement 

 on the old jars, I now wish to publish and dedicate it to the free 

 use of the entomological fraternity. It consists of a glass jar or 

 bottle of any size, having a good stopper, made of cork or rub- 

 ber, preferably the latter, through which is inserted a strong 

 glass tube, to contain the cyanide of potassium. 



This tube should be closed at the upper or outside end. After 

 filling the tube with the cyanide, the lower end can be plugged 

 with a roll of blotting paper or any porous substance that will 

 allow the fumes to escape into the jar. The insertion of the 

 tube through the stopper should be done in a neat and thorough 

 manner, so that the fumes cannot escape and that the tube can- 

 not slip in or out. If a large rubber stopper is used make the 

 hole somewhat smaller than the tube and force the latter through 

 the hole with pressure. 



The advantages of this killing-jar over the old style of jars are 

 many : — 



The Cyanide is always in sight. 



It does not dissolve so readily. 



It cannot " muss " the specimens or the hands. 



It is easily renewed or recharged. 



The same stopper and charged tube can be used on any num- 

 ber of jars or bottles of the same size. Last, but not least, the 

 jar can, after each day's collecting, be thoroughly washed and 

 dried. This is really i/ie advantage, for a clean jar is necessary 

 to clean, satisfactory collecting.
