THELYDRIAS Mots. 
T. contractus Mots. This odd little species, described in our fauna as 
“Ignotus senigmaticus” is a recent introduction, and as yet found 
only in entomological collections in and near New York City, where 
it functions as a museum pest of the first order. Its systematic posi¬ 
tion is in doubt, and its reference here is due to its relation to the 
“Drilini,” of which we have no representatives. The possibilities of 
injury to stored products should this insect spread cannot yet be esti¬ 
mated.
