On October 27, 1900, while walking through some woods along a creek near Wooster, Ohio, my attention was drawn to some white masses on Black Alder (Ilex verticillata, Gray). These masses proved to be plant lice covered with a white down. A couple of branches were broken off and taken home. There were found among these masses of lice, and concealed by them, several small, slug-like larvæ about .75 inch in length. The lice, through the kindness of Prof. F. M. Webster, were identified as Schizoneura tessellata, Fitch.

The larvæ in a few days became restless, as if wishing to pupate, and on being given a suitable place, soon fastened themselves up, and within a day or two passed into the pupal stage; then we knew that we had the curions monkey-faced pupæ of the little butterfly, Feniseca tarquinius. In all, six of these pupæ were obtained, but owing to unfavorable conditions only three of them developed to adults. Other larvæ were found about the first of November, but owing to severe cold weather the majority had perished. Some of these last larvæ were not fully grown, and could hardly have belonged to the first brood.
