 \-einl)er 25. On Januar\- 17, 18f)(j, I received front Dr. I\o1)ert Iless- 

 ier, of Logansi)ort. Ind., a pillbox of Cayenne pepper in which 

 were a dozen or more adult specimens of this Iteetle. The l)ox was 

 ])laced in a drawer of my desk and n(^t opened again until ^fareh 

 20, when the beetles were as bvely as ever. On September 14 it was 

 opened for the third time. Two liviim' adnlts and numerous half- 

 grown larva' were found therein, together with tlie inieaten bodits 

 of the dead adults. Fhc pepi)er being perfectly dry, the ([uestion 

 arises: ITow did the insects seeare .sufficient moisture to live and 

 Hourish when enclosed in so small a box? P)0th this and the ])r(>- 

 cedinu' are imported species, and boll, ure occasi()nall\- museu :i 

 pests, pre\ ing upcui dried insects, etc. The best reiiKMly is the bi- 

 sul])hide of carbon treatment, as described on pre.-eiling pages.
