FURTHER NOTES ON PSYLLIDAE TAKEN IN ALBERTA. (HOMOPTERA)

Abstract

In 1938 (1) we recorded twenty-eight species of Psyllidae which had been captured in Alberta. Of these, twenty-one were taken, for the first time on record, during the summer of 1937. Although psyllids were far less numerous in 1938 than they had been in 1937, it is now possible to add eleven additional records to the list of species which occur in this province. These include three previously undescribed forms all of which are described by Caldwell in an accompanying article. We are indebted to Mr. Caldwell, also, for the determination of the other species here recorded.
