 Both are introduced species, occurring in meal, farina and other 

 cereals in stores and granaries. They eat also the eggs and larva? 

 of other meal insects and the dead of their own kind; but not the 

 cast skins of their own larvae. Remedial measures where such are 

 needed are as for other of the granary insects already dealt with.
