Franklin (1913) (p. 448) stated, “There is not vet a single new world account of a Psithyrus having been found in a Bombus nest”. Since then, of the seven North American species, four have been reported found in nests of Bombus spp. by Sladen (1915), Frison (1916, 1921, 1926), Plath (1934), Linsley (1944), and Leech (1947). Of these records only two are from Canada, both being from British Columbia. Sladen (1915) reported finding the well-preserved body of a female of Psithyrus insularis (Sm.) and several cocoons, from one of which he extracted a male of P. insularis, in a nest containing an old queen and several workers of Bombus flavifrons Cress. Leech (1947) found a P. insularis female in a nest containing several workers of Bombus mixtus Cress., and concluded that the iniquiline had supplanted the mixtus queen.

This species has apparently been introduced in recent years and become established as a pest of the common native alder (Alnus rubra) on the west coast of Washington and British Columbia, particularly in the lower part of the Fraser River Valley. The earliest specimens I have at hand are a series of 15 females taken at White Rock, B. C., June 28, 1929, collected by Mr. G. Beall.

AbstractNorth American Ips of Group II (Hopping, 196îb) are I. emarginatus (Leconre) and I. knattsi Swaine. They are the only Ips having the third declivital spine emarginate ar the tip. They breed in various species of pine. The distribution of I. emarginatus is from southern British Columbia to California and eastward to Montana. I. knausi is found in Colorado, New Mexico and Arizona. A key to the species is given. I. plastographus (Leconte) is the sole representative of Group III. It is the only four-spined Ips with the sutures of the autennal club strongly angled at the middle. I. plastographus breeds in species of pine. It occurs from southern British Columbia southward in the western United States and through Mexico into Guatemala. Hosts and more detailed distributions are given for species in Groups IT and III.

Area Of Origin

African machairodont specimens previously referred to three species of Megantereon are considered to represent a single species in turn argued to be conspecific with the Eurasian species Megantereon cultridens (Cuvier). The area of origin of Megantereon remains unclear, but doubt is expressed about claims for an earliest appearance of the genus in North America. It is probable that the North American species M. hesperus is a junior synonym of M. cultridens.

Abstract The description of a new species of an erymid lobster, Stenodactylina beardi, from the Upper Cretaceous Haslam Formation of the Nanaimo Group on Vancouver Island, British Columbia, Canada, brings to fifteen the number of Erymidae in North America. The species are arrayed within five genera based upon configuration of carapace groove morphology, resulting in two new combinations, Stenodactylina bordenensis (Copeland, 1960) and S. foersteri (Feldmann, 1979). The new species exhibits for the first time a male pleopod and accessory structures within Erymoidea. We also provide a list of the North American species of Erymoidea.

Leaves of 51 species and three varieties of Lotus (Leguminosae) were assessed quantitatively for hydrocyanic acid (HCN) reaction intensity and the data correlated with basic chromosome number and geographic distribution. The presence of HCN was determined from 0.05 grams of fresh leaf samples by the picric acid – filter paper technique. A gradation of 10 different color reactions (−), (±), and (+1 to +8) was used to compare the HCN reaction for each species. On the basis of potassium cyanide equivalents, each gram of fresh leaf material was estimated to contain an amount of HCN which varied between the different plants and accessions from 0.5 mg to 750 mg. Most of the Old World species were positive for HCN, whereas the reverse was true for the North American species. This would favor the previous separation of the North American species into a separate genus Hosackia. All of the n = 7 species have a greater concentration of HCN than the n = 6 species in both the Old and New World. None of the n = 6 species in the New World reacted positively. Therefore, there was a reduction of HCN with evolutionary development. Two colchicine-induced tetraploids (4x = 24, 28) gave a lower HCN reaction than their diploid counterparts. Leaves of L. siliquosus (n = 7) reacted negatively to the HCN test; however, the cotyledons gave a highly positive reaction supporting the retention of the generic name Tetragonolobus (T. siliquosus (L.) Roth.) for this species. Chromosome number determinations are reported for the first time for L. holosericeus Webb and Berth. (2n = 14), L. mascaensis Buchard (2n = 28), L. nevadensis Greene (2n = 14), L. helleri Britton (2n = 14), and L. oblongifolius var. nevadensis (Gray) Munz (2n = 14).
