Insects .in the Dried Stems. 



On several occasions during the fall indications of insect activity 

 have been observed in the dried hibiscus stems remaining in the field. 

 In quite a few instances dead stems had the pith removed and the 

 channel divided off into cells. These cells contained dried pupal 

 shells, evidently those of a hymenopteron. In another instance, we 

 found somewhat similar cells in the pith packed with plant lice, which 

 had evidently been stored there by a species of Pemphredonidse.
