Howard. Vigo, :\Iarion, Putnajn and Lawrence counties; fre- 

 quent locally. April 10-Noveraber 7. Specimens in all stages 

 were found in smoking tobacco put up in tin boxes on the earlier 

 date. Widely distributed over the world by commerce and feeds 

 on a variety of dried vegetable products, such as cayenne pepper, 

 ginger, rhubarb, rice, figs, yeast cakes and prepared fish food. To- 

 bacco it devours in every form, in the leaf and when made up into 

 chewing plug, cigarettes and cigars. It is, therefore, often known 

 as the ' ' cigarette beetle. ' ' Both it and the larva? may be destroyed 

 by submitting them to the fumes of bisulphide of carbon, or by 

 steaming the substance in which they are found. Drugs which 

 are badly infested should, however, be burned.
