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, effective, and 
almost universally applicable remedy.
