Note: page 74 is missing from archival and circulating copies / The present state af knowledge of the order Thysanaptera in Canada is reviewed. The aoder has been sorely neglected since Provenchar submitted a list af 35 eastern Canadian species in 1890. In contrast to the latest previaus estimate of 102 species (Heming, 1979), the number of species found in this study is 174 (143 described and 31 undescribed species). One new genus and five new species are reported as well as the European species Odontothrips biuncus which has been found for the first time in North America. Descriptions, illustrations and a dichatamaus key to the Canadian genera of the Thysanaptera ara given for the first time. Also included are lists of the species. hitherto found in Canada along with their localities•• and habitats•• In addition, an alternative computer-compatible key is presented for the suborder Tubullfera. The distribution and study af the order in Canada are discussed and notes on collection, classification, biology and economic importance are given. / Ce travail revise l’etat de nos cannais.ance. sur l’ordre de. Thysanopteres au Canada. Ce groupe a fait l’objet de peu d’etudes depuis la publication de Provencher (1890), qui enumerait 35 especes pour l’est du Canada. Dans la presente etude, nous rapportons . 174 especes (143 especes decrites, 31 especes non decrit••) alors qu’Heming (1979) n’en citait que 102 especes. pour ce pays. On y cree un nouveau genre et 5 nouvelles especes, en plus de recolter pour la premiere fois l’espece europeanne, Odonthrips biuncus en Amerique du Nord. L’auteur decrit et illustre pour la premiere fois. les. genres de Thvsanoptere. representes dans la fauna canadienne. De plus, on y trouve une liste des especes presentes au Canada, accompagnee de notes sur leur repartition geographique et leur habitat. On y inclut un tableau dichotomique conventionnel ainsi qu’un tableau de determination adape a l’ordinateur. pour Ie sous-ordre des Tubuliferes. Ce travail fournit egalemant, pour les Thysanopteres du Canada, une discussion sur leur repartition Geographique et des renseignements sur leur recolte et classification, leur biologie et importance economique.
