Until 1951 the Canadian National Collection of Insects lacked specimens of the barberry geometrid, Coryphista meadi (Packard), from Eastern Canada. In that year Mr. W. E. Whitehead, Macdonald College, Que., forwarded for identification two specimens taken in Kings County, N.S., and on learning of the interest of the record he kindly presented them to the National Collection. In 1952 an outbreak of the species in the Ottawa region caused minor damage to ornamental barberry bushes. Several enquiries about the insect were received, and MacKay (in preparation) studied its life-history.
