Description:
<jats:p>In answer to Dr. Butler's comments (Can. Ent. XXXI., p. 19) upon my revision of the species of <jats:italic>Euchloé</jats:italic> (Bull. Am. Mus. Nat. Hist., X., pp. 235-248), I could state that Dr. Butler may possibly be right in considering <jats:italic>creusa</jats:italic> (var. <jats:italic>elsa</jats:italic>), <jats:italic>hyantis</jats:italic> and <jats:italic>lotta</jats:italic> seasonal forms of <jats:italic>ausonides</jats:italic>, but with the present knowledge it is not possible to place them so, and for this reason I concluded it would be best to allow the species to remain distinct until more light could be obtained on the subject. At any rate I was certain that what we had labeled in our collections as <jats:italic>creusa</jats:italic> was not Doubleday and Hewitson's species, which Dr. Butler definitely asserts is my var. <jats:italic>elsa</jats:italic>.</jats:p>
