Until recently I have been applying the name caryaefoliella Clem. to the common species of eastern Ontario, the cases of which are found on hickory (C. glabra and C. cordiformis) and which I mentioned and figured in one of my previous papers (1933, Can. Ent., LXV, 161, Pl. X, figs. 19-21). However in early June, 1944, Mr. T. N. Freeman collected a number of cases on shag-bark hickory (C. ovata) at Pt. Rowan in southern Ontario which produced adults very similar in color and maculation, it is true, to our eastern Ontario species, but differing markedly in male genitalic characters.

In July 11, 1945, in the city of St. Catharines, Ontario, while looking for some elm trees reported by Dutch elm disease scouts as being severely leaf-eaten, I found two white elms (Ulmus americana L.) carrying large numbers of coleopterous larvae which were at once taken to be referable to the elm leaf beetle, Galerucella xanthomelaena (Schr.)
