Twenty-nine species and named subspecies of Calligrapha Chev., including eight species previously undescribed, are listed below with notes on food-plant, distribution, and variability. New names are offered for the hamonyms elegans (Olivier) and similis (Rogers). The records and notes, except those credited to authors, are based almost entirely on material in the Canadian National Collection.

The genus Glutops has been known to contain but one species, the very rare fly Glutops singularis Burgess. Probably most of the collection records of G. singularis have been published and these number less than a dozen, the records being restricted to the states of New Hampshire, Massachusetts, Connecticut, New York and Pennsylvania. To the published records the writer might add that of a female specimen collected at the Cornell Wild Flower Preserve, Slaterville, New York, on June 1, 1935.

It is often important to the successful conclusion of insect field-studies to know the air temperatures which govern insect activities, particularly the minimum temperature at which flight occurs. In the field, this is usually a matter of continued observations on the relative abundance of a species, correlated to some degree with observations on the air temperatures at the times of abundance or of flight.
