A New Species

From a study of living materials and specimens in several regional herbaria, a list has been drawn up of all the common and several of the rarer tube-dwelling diatoms of eastern Canada. Descriptions, illustrations of living material and acid-cleaned valves, and a key to the species are provided. Most specimens were from the Atlantic Provinces and the St. Lawrence estuary, but a few were from the Northwest Territories. By far the most common species is Berkeleya rutilans. Other species occurring commonly in the Quoddy Region of the Bay of Fundy, and sporadically in space and time elsewhere, arc Navicula delognei (two forms), Nav. pseudocomoides, Nav. smithii, Haslea crucigera, and a new species, Nav.rusticensis. Navicula ramosissima and Nav. mollis in eastern Canada are usually found as scattered cohabitants in tubes of other species. Nitzschia tubicola and Nz. fontifuga also occur sporadically as cohabitants.

Two of the three species recorded in this paper (Ceratonereis scotiae sp. n. and Nereis diversicolor O. F. Müller) were collected some years ago, but hitherto their occurrence has not been noted. The third (Tharyx marioni (Saint-Joseph)) was collected recently for the first time in Canadian waters.

AbstractDioryctria resinosella, a species feeding on red pine cones or shoots, is described as new and recorded from Maine, southern Ontario, Wisconsin, and Minnesota. The new species is distinguished from D. zimmermani (Grote) and D. banksiella Mutuura & Munroe by the differences in wing markings, genitalia characters, and ecological aspects.

A New Species

A study was made of organisms concerned with the red discoloration of salted hides, also termed "red heat", which defect may occasion loss in the leather industry through spotting and weakening of the fibre. Red halophilic sarcinae were isolated from Argentine hide. From Canadian hides showing red discoloration, two species of pleomorphic rods were isolated as active agents. One of these, occurring on salted cowhides, was found to be similar to Serratia salinaria (Harrison and Kennedy) Bergey et al., a source of reddening of cured codfish in eastern Canada. The other organism causing discoloration, isolated from buffalo hide, was regarded as a new species and designated Serratia cutirubra n.sp. Both of these halophilic organisms, owing to their proteolytic action, are considered capable of greater damage to hides than the red sarcinal types which are non-liquefying, and which may also be present on Canadian hides. Non-chromogenic halophilic bacteria were also isolated from discolored hides. These develop at a lower salt concentration range than the red organisms and are probably less active in causing injury to fibre in well salted hides.

Its morphological attributes, hosts, and distribution are compared with those of apparently its most closely related species, Ixodes (Pholeoixodes) texanus Banks.

Genetic Experiment

The present study is the result of combining genetics with taxonomy in the investigation of a polymorphic group of wild plants. It shows a degree of multiformity which was hitherto unsuspected in the genus. All the early genetical work on Oenothera was done with species which had been naturalized in Europe and whose North American home was unknown. Later, de vries (1913) introduced various American forms into cultivation and used them in genetic experiment, but without full taxonomic descriptions. Bartlett was mainly concerned in describing about twenty-five new species from wild plants of eastern North America brought into cultivation, and the present writer has previously described five, all but one of them from Eastern Canada. Professional taxonomists have paid little attention to the Onagra section of the genus except for the occasional description of a new species from western North America, and the whole number of species now recognized and described is about 70, not counting the 17 new species and 15 new varieties described in the present paper. The reason for the neglect of the taxonomists, even after the mutation work concentrated a great deal of attention on the genus, was no doubt the difficulty that many of the characters are not well shown in ordinary herbarium material. Indeed, cultures are necessary in order to study adequately the characters of these forms ; but, on the other hand, species once clearly delimited in this way can be recognized in the field, at least when well-developed plants are available, and frequently from the rosette stage alone.

A New Species

The following is a description of a new species of leafhopper from Eastern Canada of the subgenus Cloanthanus of the genus Scaphytopius. A key to the known Canadian species of Cloanthanus is included. Two of these species, angustatus (Osb.) and argutus DeL., do not appear to have been recorded previously for Canada. The key is based primarily on structures of the male genitalia, as these show the most reliable specific characters. External characters of colour, markings, and structure are often unreliable, because of the variation that occurs. There is occasionally some variation in the genitalic characters, notably in the degrees of curvature of the paraphyses, but the general shape of each structure is sufficiently constant to provide reliable specific characters. This subgenus, which was revised by Hepner (1947), is poorly represented in Canada, as the majority of the species have southerly distributions in North America. The common Canadian species is acutus (Say), followed by latus (Baker); the remaining species are more restricted in their ranges and distributions in Canada.
