The crickets, or Gryllidæ, like the other families of Orthoptera, have received so little attention from Canadian entomologists that very few species have been reported from the country, and most of these few records are of little value, as they were made at a time when the family had been little studied, and the species wre ill define. Much has been done of late, however, by American entomologists, notably Sucuder and Blatchely, to unravel these difficulites, although the family is still a very diffucult one to deal with, and much patience and close observation is necessary in order to separate the species satisfactorily.
