The following species, which have been described by Drs. Packard and Fitch, I have not met with. But for the convenience of those who may not have access to the writings of these gentleman, I condense the fol1owing account:–

1. L. Argentifimbriella Clem. has been already mentioned at p. 57. It mines the under surface of leaves of the Chestnut oak and must resemble L. caryae-albella or L. lucidicostella. At p. 57, ante, it is suggested that L. querci-albella fitch may be the same insect. Dr. Fitch states that it mines the leaves of the White and chestnut Oaks indifferently. But Dr. Clemens says that Argentifimbriella makes a tent mine on the under side, has a cylindrical larva, and pupales suspended in a thin web in the mine like L. lucidicostella.
