          Abstract

          Characteristics of the cocoons, cephalic structures, spiracles, and skins of 97 species and 19 genera of the tribe Campoplegini (Hymenoptera: Ichneumonidae: Campopleginae) are described and illustrated and keys are given for identification of the genera and species. An additional five species and two genera that were described and illustrated in earlier papers (Finlayson 1967, 1969) are included in the keys, for a total of 102 species and 21 genera. Characteristics of final-instar larvae were found that support most of the generic entities defined on the basis of adult characteristics, and new relationships were revealed that may assist with taxonomic problems in the group.

          Résumé

          L'auteur présente la description illustrée des caractéristiques des cocons, structures céphaliques, stigmates et exuvies de 97 espèces et 19 genres de la tribu des Campoplegini (Hymenoptera : Ichneumonidae : Campopleginae), accompagnée des clés d'identification au genre et à l'espèce. Cinq espèces et deux genres dont la description illustrée avait été faite précédemment par l'auteur (Finlayson 1967, 1969) sont inclus dans les clés pour un total de 102 espèces et 21 genres. Le présent travail a permis de trouver des caractéres propres au dernier stade larvaire confirmant dans leur position la plupart des entités génériques dont la définition était basée sur des caractéres de l'adulte; l'étude a également permis d'établir de nouvelles relations qui sont de nature à faciliter la solution des problèmes taxonomiques propres à ce groupe.

          A NEW CLASSIFICATION OF THE BRACONIDAE (HYMENOPTERA) BASED ON THE CEPHALIC STRUCTURES OF THE FINAL INSTAR LARVA AND BIOLOGICAL EVIDENCE

           M. Capek (1970)
          The cephalic structures of the final instar larva of 278 species of 140 genera of Braconidae were examined. On the basis of these and biological data, modifications are proposed in the classification of the higher categories. Zele (Helconinae) and Eubadizon (Blacinae) are placed in the Macrocentrinae (endoparasites of larval Lepidoptera) and Meteoridea is moved from the Helconinae and ranked as an independent subfamily. The Blacinae is completely dismembered: Aliolus , Triaspis , Urosigalphus , Blacus , and Calyptus form a tribe of the Helconinae (endoparasites of larval Coleoptera); Microtypus , Orgilus , and Stantonia form a tribe of the Agathidinae (endoparasites of larval Lepidoptera); and Pygostolus , Centistes , and Syrrhizus a subfamily near Euphorinae with Cosmophorus (endoparasites of adult Coleoptera). Present genera of Microgasterinae are separated into two tribes with the addition of the Cardiochilini as a third tribe. The Dacnusinae is reduced to a tribe of the Alysiinae. The Rogadinae is reduced to one tribe, Rogadini, containing only Rogas and allied genera (endoparasites of larval Lepidoptera). Rhyssalus is transferred to the Hecabolini, and Exothecini, Pambolini, Hormiini, and ectoparasitic Rogadini to the Braconinae (ectoparasites of larval Coleoptera, Lepidoptera, etc.). The problematic genus Gnaptodon is also placed in the Braconinae.

              THE HYMENOPTEROUS PARASITES (HYMENOPTERA: APHIDIIDAE ET APHELINIDAE) OF THE PEA APHID IN EASTERN NORTH AMERICA

              The adults, mummies, and final-instar larvae of the eight hymenopterous parasites of the pea aphid, Acyrthosiphon pisum (Harris), in Eastern Canada are described and illustrated. The history, synonymy, and biology of each species, and the problems of species differentiation in two of the genera, Aphidius and Praon , are discussed. Keys are given to separate the adults, mummies, and cast skins of the last larval instar.
