Dr. Hulst describes the species and X. longula in May Can. Ent., p. 119. The National Museum has a long series of these (225 specimens), very variable, but doubtless representing only a single species. In spite of the label, I am of the opinion that Dr. Hulst's types are not American specimens. Some bear a printed label “Alaska” and “Coll. C. V. Riley”; others have a written label “Behring Island, Alaska” and others “Behring Island.” I think the whole series were collected by Dr. Stejneger at Behring Island, which is one of the Commander Islands off the coast of Kamchatka, and has in general an Asiatic fauna. It is unfortunate that these seductive little “Alaska” labels were used on the specimens.
