Stratigraphic Range

Mixodectidae (Mammalia, Archonta) are an unusual, poorly known family of dermopteran-like mammals that have been discovered at several North American localities of primarily early Paleocene age. Among the three or four recognized mixodectid genera, Eudaemonema Simpson is perhaps one of the least understood, being known from only a few localities of late Torrejonian and earliest Tiffanian age. This paper reports on a new species of Eudaemonema from the late Paleocene of Alberta, Canada, that significantly extends the geographic and stratigraphic ranges of the genus. Eudaemonema webbi sp. nov. is known from middle and late Tiffanian localities in central and south central Alberta, and it represents the youngest and northernmost species of Eudaemonema so far discovered. E. webbi differs from the genotypic species E. cuspidata in being larger and in having a suite of dental characters (e.g., molariform posterior premolars, enlarged molar protocone and hypocone, development of a second grinding platform on the lower molars) that suggests an increased emphasis on grinding during mastication. E. webbi possesses several dental features (e.g., broad, shelf-like molar paraconid–paracristid, lingually shifted molar hypoconulid) that resemble those of cynocephalids (Mammalia, Dermoptera), with these resemblances interpreted herein as convergent. The occurrence of E. webbi at Gao Mine extends the stratigraphic range of Eudaemonema into the late Tiffanian (Ti5) and represents the youngest known record of Mixodectidae.

Among the many interesting Homoptera which have been sent to me by Professor E. H. Strickland is a series of an unusual Delphacodes collected at Cooking Lake, Alberta. This distinct little species is described at this time in order to stimulate further collection of these inconspicuous but interesting insects from western Canada, where there must be many more new species as yet unrecorded.

A New Species

A new species of stem actinopterygian, Helmolepis cyphognatus sp. nov., is reported from the Lower Triassic Sulphur Mountain Formation of western Canada (probably Smithian). This taxon differs from the only other known Early Triassic platysiagid, H. gracilis from the Lower Triassic Wordie Creek Formation of East Greenland (Griesbachian), in counts of branchiostegal rays, shape of the maxilla, shape (and possibly counts) of extrascapulars, and the size ratio of major opercular bones. In spite of their overall unfavorable preservation, the numerous available specimens amend our knowledge of the little known genus Helmolepis considerably: it has become evident that the morphology of Helmolepis cyphognatus sp. nov. comes closest to Platysiagum minus (Middle Triassic Besano Formation of central Europe). This study suggests placement of the two genera in the family Platysiagidae. Investigation of this new species also shows certain features of the cheek and the caudal fin are more primitive than previously believed, whereas the snout region is probably derived but of yet uncertain affinities in Helmolepis.

A New Species

Among a large number of Orthoptera taken by muyself during a trip ot the Pacific Coast by the Canadian Pacific Railway there is one species belonging to the Melanopli which I was unable to determine from Scudder's “Revision” of the group, and could not even satisfy myself as to its generic place. I therefore sent a pair to Mr. Scudder, who informed me that it was a new species of Asemoplus, but that a change would be necessary in the description of that genus as given in his “Revision of the Melanopli” in order to receive my species. I had noticed the resemblance to Asemoplus in the extremity of the male abdomen, but the total absence of tegmina and other points of dissimilarity caused my uncertainty regarding its true generic position.

Male Genital

Recent study of the male genitalia in the Miridae (Kelton, 1959) showed that the Palearctic Stenodema virens (L.) does not occur in North America. The six other species that have been reported in the North American literature are: dorsolis (Say), vicinum (Prov.), trispinosum Reut., sequoiae Bliven, falki Bliven, and imperii Bliven. The three species described by Bliven (1955, 1958) were not available to me for study, however, Bliven (1960) has recently published a paper containing figures of the male genital claspers of these species. These appear to differ considerably from those of virens, vicinum and trispinosum as well as amongst themselves.

A New Species

A new species of pyrenomycete, Nodulosphaeria edgari, is described from western Canada and western U.S.A. A closely related species, Nodulosphaeria olivacea (Ellis) L. Holm, is redescribed from the lectotype and additional collections from western U.S.A. The two species sometimes occur together on the same host plant material. Nodulosphaeria edgari was previously reported from western U.S.A. under the misapplied names Leptosphaeria erigerontis (Berlese) Berlese and Nodulosphaeria olivacea. Species concepts are stabilized based on type studies of the three taxa. Host plant and geographic records are revised.
