The cosmopolitan and omnivorous little Sitrodrepa panicea was by 

 far the most abundant and wide spread in the store-rooms. It is really 

 a serious pest of stored drugs. In the case of the cantharides attacked 

 by it the bodies of the cantharis beetles were completely riddled and 

 broken. Of the thousands of bodies in the canister not one seemed to 

 have been left unattacked. In many other instances the damage done 

 to the drug was considerable. 



The remedy, other than preventing the ingress of the insects by 

 using tight jars and canisters, is to expose the infested drug to the 

 vapor of carbon bisulphide. The ease with which this may be done in 

 the case of most drugs gives the druggist a feasible, eftective, and 

 almost universally applicable remedy.
