The immature stages of Euxoa basalis (Grote) are described and illustrated. Both the egg and pupa are similar to those of other Euxoa species and are virtually indistinguishable from some of them. The larva although morphologically quite similar to other Euxoa larvae is distinctive in coloration, particularly in the penultimate and ultimate stadia. Each of the larval instars is described; the ultimate instar in detail, the others briefly. A redescription of the adult is also given.
