Our knowledge of the crane-flies of Labrador is still very insufficient. The most extensive collections that have yet been made are those of Mr. W. W. Perrett, taken in the years 1922 to 1925, inclusive, at and near Hopedale. This important series is the property of the Canadian National Collection and was kindly loaned to me for examination by Mr. Curran, to whom I would express my sincere gratitude.

Patagonicola Packer new genus is described for two species of xeromelissine bee (Hymenoptera: Colletidae) from Patagonian Argentina. One species, P. graveli Packer new species is described; the second species, P. aenigma (Packer) new combination, originally placed in Chilicola Spinola, 1851 subgenus Chilioediscelis Toro and Moldenke, 1979, is designated as the type species. The new genus is superficially most similar to Xenochilicola Toro and Moldenke, 1979 but possesses none of the derived characteristics that were originally used to define that genus. Results of a phylogenetic analysis, based upon 114 morphological characters, are presented and suggest that the new genus is the sister clade to (Geodiscelis Michener and Rozen, 1999 + Xeromelissa Cockerell, 1926). An illustrated key is provided for the genera of Xeromelissinae and for the two species of Patagonicola.

Four new Cerambycidae (Coleoptera) species and two new genera are described from Ecuador: Blabia albosetanew species (Lamiinae: Desmiphorini); Alloblabianew genus, type species, A. praecipuanew species (Lamiinae: Desmiphorini); Alicalnew genus, type species, A. tuberculatusnew species (Lamiinae: Calliini); and Piola schiffinew species (Lamiinae: Phacellini). The new species of Blabia Thomson, 1864 and Piola Marinoni, 1974, and Alical are included in modified published keys.

Trialeurodes abutiloneus (Haldeman) (Hemiptera: Aleyrodidae) is known to have been present in Canada since 1973. Despite this, the species has until now not been officially recorded; a surprising fact considering the close association of the species with economically important crops. The historic distribution expands from Mexico to southern New York and Michigan in the United States of America. In 2016, all life stages of T. abutiloneus were collected again on soybean (Glycine max (Linnaeus) Merrill; Fabaceae) plants grown in research greenhouses in southwestern Ontario, Canada. Specimens were morphologically and genetically identified to confirm their identity as T. abutiloneus. Thereafter, the barcode sequence for this species was also identified from the barcode of life data system, informing on the prior detection of this species from specimens collected at Point Pelee National Park, Ontario, Canada in 2012 during a barcode of life collection. Although this species is not considered a major pest on crops in Canada, it is related to other common pests within the same genus and can potentially transmit similar plant diseases. We provide the barcode COI sequence for the species, give an overview of the documented host range pertinent to Canada, and provide information concerning its natural enemies.

During the summers of 1901–2, while at the Minnesota Seaside Station of Vancouver Island, Professor Raymond C. Osburn collected a number of Diptera, and during the these same seasons and the past summer Professor R. V. Harvey, of The Queen's School at Vancouver, British Columbia, collected in the same order. Since so little has been published on the Diptera of that province, we have thought that even a short paper on the Dipterological fauna would be of interest and probably of some value.

Euxoa ustulata n. sp., allied to Euxoa perexcellens (Grote), is described from northern California. Adults and genitalia of both species are illustrated.

Airplane application of the insect growth regulator CGA 13353, a juvenile hormone mimic used experimentally against spruce budworm, Choristoneura fumiferana (Clem.), did not drastically reduce percentage parasitism in field samples of that host, but there was some evidence of susceptibility. Exploratory sampling of maple defoliators suggested that one species and its parasitoids suffered some mortality, but another species and its parasitoids did not. The treatment did not influence the viability of ant colonies.

In order to determine the transference of Bacillus thuringiensis Berliner (Bacillaceae) (Bt) insecticidal protein in the food chain, enzyme-linked immunosorbent assay was used to detect Bt insecticidal protein levels in transgenic Bt cotton (GK12, New variety 33B and SGK321), Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae) fed on the Bt cotton varieties, and two natural enemies of S. exigua, Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) and Microplitis pallidipes Szépligeti (Hymenoptera: Braconidae). The results showed that Bt insecticidal protein was found not only in cotton leaves, but also in the body and excrement of S. exigua and the bodies of both C. carnea and M. pallidipes. Bt toxin was detected in S. exigua larvae of all the examined instars (second, third, fourth, and fifth) that fed on transgenic cotton varieties and the Bt toxin level was the highest in the body of the second instar. In addition, the Bt toxin content in the excrement of the second instar was lower than that in the older ones. After the natural enemies C. carnea and M. pallidipes preyed/parasitised the S. exigua larvae that fed on transgenic cotton, Bt toxin was found in both the predator and parasite. This research indicates that Bt protein can be transferred through the food chain and to natural enemies of various predatory habits.

Several instances a disastrous and even fatal effects to valuable pearorchards from being attacked by the Psylla have come under my observation, as well as entirely satisfactory results from treating the trees.

The life-history and habits of injurious insects must be accurately determined before we can know just how to deal with them. A knowledge of the habits of such insects will also often enable the farmer to so manage his land crops that the insects are placed under unfavourable and even destructive conditions.

Professor W.H. Brittain has sent me a small lot of Andrena collected this year, and among them I find a species so striking that it should be described at once. As I am leaving for Africa it will be impossible to deal with the rest of the collection at this time.

Chrysomela scalaris Lec. The question asked by Dr. Hagen in the June number concerning the name of this insect, is more easy to answer than to arrive at a definite conclusion. Stal, in his monograph, did not recognise many of the genera into which Chrysomela had been divided; among them were Doryphora and Leptinotarsa. Finding that Olivier in 1807 had described a D. scalaris, and the Maj. LeConte in 1824 a Chrys. scalaris, Stal superseded the latter name by multiguttis. Recent authors are in accord in adopting many of the genera rejected by Stal, and the name originally given our species becomes valid and has been adopted by Jacoby (Biol. Cent. Am., vi, pt. i., p. 197, pl. xi., fig. 6). That the name should remain in future Calligrapha scalaris is fortunate, since we have lately received from Arizona a specimen of Calligrapha multiguttata Stal (in cab. Lec.), which is well figured in the work above cited, pl. x., fig. 5.

After a journey of ten miles over snow and snowbanks from four to eight feet deep, I arrived in the latter part of June, on my summer and fall collecting ground on the Fuloumne Meadows, which lie on the edge of the area wherein the high Sierra species of Lepidoptera are most numerous. The Paranassius was one of the first I began to collect, as the butterflies had just commenced to issue, and were flying in the grassy and shaded timber-covered portions of a rocky side hill slope.

The fact that the petiole of the nest of P. annularis is thickened from time to time as the weight of the nest increases shows that the wasps can adapt their behavior to the needs of the day, even though their chain of work is interrupted. The first part of the nest to be made is the petiole; this is made by the queen long before the first workers emerge.

Fore wings pale carneous brown shaded with dusky; terminal space more blackish. Median lines fine, black, approximate, angulate. A curved sub-basal shade on internal margin. Reniform narrow, outwardly curved or oblique, white and contrasting, set in a dark suffusion of the disc. Subterminal line even, with a costal angulation. A fine dark terminal line at base of concolorous fringes. Hind wings pale, shining with traces of median shades and the fringes slightly carneous ; abdomen concolorous with hind wings.

On 15 November 1971, during collection of galled balsam fir needles from two experimental plots in Edinburg, Maine, damaged galls were noted. The galls had obviously been torn open (Fig. 1). Since this was not recorded in the literature and damaged galls were numerous, the situation was evaluated.
