On August 28, 1949, over beach drift and seaweed at Matane on the Gaspé Peninsula, Quebec, the writer collected a series of flies presumed to be Coelopa frigida (F.). Later examination revealed the capture of two males of Orygma luctuosa Meigen, a peculiar coelopid fly with small eyes, extremely broad cheeks, and broad, flat facial carina. Inasmuch as this European species had apparently been recorded only once before from North America, it seemed desirabie to place the find on record.

An account is given of seminatural communities in the Gaspé Peninsula in which Alchemilla subcrenata Bus. is abundant. Evidence is brought forward to show that this species (a segregate of the apomictic complex Alchemilla vulgaris) has been introduced at some period since 1930. It is now completely naturalized. The bearing of this fact on the status of Alchemilla species in North America and in some European areas is briefly considered.

Three species of rough fescues occur in Canada and the adjacent part of the U.S.A.: Festuca altaica, F. campestris (F. scabrella var. major), and F. halli. Festuca altaica, a wide-ranging species of eastern Asia and northern North America, extends southward in the Canadian Cordillera to about latitude 52° N and is disjunct in eastern Canada (northern Québec, Gaspé Peninsula, western Newfoundland, etc.). Festuca scabrella Torr. in Hook, is a synonym of the earlier published F. altaica Trin. in Ledeb. Rough fescues of southern British Columbia, the southern prairie provinces of Canada, and northwestern U.S.A. that have been called F. scabrella belong to F. campestris and F. hallii, a neglected species. A key to the three taxa and a map of their distribution is presented.

Extensive field studies and evaluation of previously published reports reveal a moss flora of at least 310 species for the Gaspé Peninsula. Forty species are reported for the first time from the peninsula, and Brachythecium glaciale is new to Quebec. While the Gaspé flora cannot be considered a distinctive one within the Gulf of St. Lawrence region, the large number of rare species is significant. Their presence in the Gaspé can be attributed to the diverse geology and topography of the peninsula. The bulk of the moss flora is clearly of boreal affinity, but many species have temperate, montane, or arctic – alpine distributions. Of special interest is the large proportion of species with various types of disjunct distributions, either within eastern North America or to other parts of the world, especially western North America. Some patterns strongly support the idea of survival in refugia in the Gulf of St. Lawrence region during the last glaciation.

Nearly all forest regions in the Province of Quebec where balsam fir (Abies balsamea (L.) Mill.) is an important tree component have been subjected to severe defoliation by the spruce budworm, Choristoneura fumiferana (Clem.), during the past 20 years. These outbreaks have followed an easterly direction beginning near the Ontario-Quebec border in 1939 and ending in the Gaspé Peninsula in 1958.

The tibiæ are usually all spinose, the eyes naked, the body untufted, the form normal, the male antennæ of various structure, pectinated, brushlike simple. The European species are refered by Lederer all to one genus, Agrotis or Hübner. Nervertheless, I think the yellow-winged forms may well be separated under Hiria and Tryphœna. Of these yellow-winged forms, with flattened abdomen, we have only one T. Chardinyi, from Anticosti and Maine, considered identical with the Siberian species of the same name, described orginally by Boisduval under Anarta.

In the following notes, two European species, one a pest of Lilium, are recorded for the first time from North America; an European pest that was introduced into the United States is recorded from Canadian localities; and a Mexican species not noted previously from the United States is recorded from Texas. The five forms described as new belong to difficult groups in which the species show strong monophagous tendencies.
