In arranging the National Collection material in Xenoschesis, two species were encountered which appear to be undescribed. The following descriptions are therefore presented with a table to the American species, which are all represented by specimens in the National Collection. Colour appears to be most valuable in separating our species and has therefore been used in the following key. The specimens before me exhibit only slight variation.
