 America with another species, Ephestia interpunctella, but in 

 1889, Professor Riley stated that there was no doubt of the

 some years back. This insect appears to have been known on 

 the Continent since 1836 — known, that is, to the owners of corn 

 stores and granaries and to millers as more or less troublesome —

 in Great Britain in 1887, though for some time previously it had 

 been doing harm in corn stores and flour mills, and its mischief
