    UPPER TRIASSIC INSECTS FROM THE MOLTENO "FORMATION", SOUTH AFRICA.
    (BERNARD PRICE INSTITUTE FOR PALAEONTOLOGICAL RESEARCH, 1974) Riek, E. F.
    Insects are recorded from eight plant fossil localities in the Molteno "Formation", but only heavily sclerotized species (Blattodea and Coleoptera) have been obtained from six of them. A small mecopteron was found at another locality, and only at Birds River, near Dordrecht, has a more diverse fauna, with representatives of the Orthoptera, ?Mantodea, Blattodea, Homoptera and Megaloptera, been obtained. The known fauna is closely comparable with the Triassic faunas of Australia. Thirteen species, nine of which are described as new, are recorded from the Molteno. Six of the new species, and one described species, are referred to Hagla, Mesorthopteron, Triassoblatta, Dysmorphoptiloides and Ademosyne, genera represented in or previously restricted to the Australian Triassic faunas. The new monotypic genera, Prosbolomorpha (type species clara: Homoptera) and Afristella (type species delicatula: Mecoptera), are similar to genera recorded from the Triassic of Australia. Euchauliodes distinctus, gen. et sp. nov., is the earliest known Corydaloidean wing (Megaloptera); it is referred to a new family.

    A FOSSIL INSECT FROM THE DWYKA SERIES OF RHODESIA
    (BERNARD PRICE INSTITUTE FOR PALAEONTOLOGICAL RESEARCH, 1974) Riek, E. F.
    Hadenlomoides dwykensis, gen. et sp. nov. (Paraplecoptera: Hadentomidael is the oldest recorded insect in the southern hemisphere. It is similar to Hadenlomum americanum from the Upper Carboniferous of North America. The close relationship between these two species tends to support the view that at least part of the Dwyka Series extends below the Permian into the Upper Carboniferous.

    A NEW SPECIMEN OF PROMOSCHORHYNCHUS PLATYRHINUS BRINK 1954 (MOSCHORHINIDAE) FROM THE DAPTOCEPHALUS-ZONE (UPPER PERMIAN) OF SOUTH AFRICA
    (BERNARD PRICE INSTITUTE FOR PALAEONTOLOGICAL RESEARCH, 1974) Mendrez, Christiane Helene
    The morphology of the skull of Promoschorhynchus platyrhinus (Moschorhinidae) from the Daptocephalus-zone (Upper Permian) of South Africa) is described with special reference to the palate and posterior part of the skull. Promoschorhynchus is compared with Moschorhinus and considered to be a vaild genus mainly differing from Moschorhinus in retaining a longer snout, and in possessing a more primitive morphology of the palatal plates of the premaxillae and vomers. Promoschorhynchus also differs from Moschorhinus in having developed a sharp crista choanalis and a fairly broad epipterygoid. The composition of the South African Moschorhinidae is briefly discussed and is considered temporarily as consisting of five genera: M oJchorhinUJ (.1 = TigriJuchuJ). CerdoPJ, PromoJchorhynchUJ and Hewittia. TigriJuchUJ and MOJchorhinuJ are probably synonyms.

    SEED-BEARING GLOSSOPTERIS LEAVES
    (BERNARD PRICE INSTITUTE FOR PALAEONTOLOGICAL RESEARCH, 1974) Kovacs-Endrody, E.
    Seeds are commonly known elements of Glossopteris floras. The connection of these seeds to any definite elements in the floras and their systematic position with it has always been uncertain, and they are usually referred to as a group "incertae sedis". Several of these seeds have been described and placed in the genera Cardiocarpus Brongniart, Cordiocarpus Geinitz and Samaropsis Goeppert, specially erected for them. Arber (1905, p . 206) noticed the common occurrence of seeds with Glossopteris leaves, and refers to them without any further conclusion as "A few seeds .. . in association with fronds of Glossopteris broumiana. The seeds are possibly referable to Cardiocarpus".
