The fact that Mr. Strecker has seen fit to misstate the circumstances under which this species was named has induced me to correct the impression he may have created as far as possible.

In the descriptional part (p. 30) we say : “We are indebted to Mr. J. W. Weidemeyer for the information respecting this singular little species, which, we believe, has not been hitherto described, while an excellent figure, shown us by Mr. S. Calverley, enables us to present the present description and to fix the species. It appears that Dr. Boisduval has etiquetted a specimen in his cabinet as Proserpinus Phaeton.”
