In the following notes, two European species, one a pest of Lilium, are recorded for the first time from North America; an European pest that was introduced into the United States is recorded from Canadian localities; and a Mexican species not noted previously from the United States is recorded from Texas. The five forms described as new belong to difficult groups in which the species show strong monophagous tendencies.

The spring of 1945 was in general very unfavorable for the majority of Lepidoptera in the Ottawa area, due apparently to the killing frosts and wet weather of the latter half of April and throughout May, following abnormally high temperatures late in March and early April. However Coleophoridae were the exception to this condition and the cases of this group were much more abundant than usual. The continued cold, dry, winter weather, without any of the customary alternating thawing and freezing spells was seemingly very suitable to the hibernating larvae; the early warmth stirred them out of their winter lethargy fully a month sooner than usual and their cases proved a protection against the subsequent cold.

Among the many interesting Homoptera which have been sent to me by Professor E. H. Strickland is a series of an unusual Delphacodes collected at Cooking Lake, Alberta. This distinct little species is described at this time in order to stimulate further collection of these inconspicuous but interesting insects from western Canada, where there must be many more new species as yet unrecorded.

Judging by the genitalic figure (based on an Ottawa male), given by Heinrich in his revision (fig. 276) and by the remarks in the text (p. 12) the species has been — at least partially — misidentified by this author. Clemens' type (selected by Fernald) is a specimen from Baltimore, Md., in the Academy collection at Philadelphia; the specimcn is unfortunately without abdomen but has recently been very carefully examined by Mr. T. N. Freeman who selected a male specimen from Oak Station, Pa. (Marloff) as almost exactly matching this type.
