Forty-three species of the Tortricid genus Peronea are dealt with, comprising all the species known to occur in Canada at the present time and including practically all of the North American ones. Characters found in both the male and female genital organs have been used as a means of specific differentiation and there are eight sets of figures illustrating these organs. The range of variation in color and pattern of the individual species is briefly discussed and records of distribution and larval food-plants are given as far as present knowledge permits. Seven species new to science are described.

The excellent results obtained by a study of both male and female genital organs when determining specimens of this difficult genus in connection nith my paper on the “Lepidoptera of Seton Lake, B. C.” have led me to continue this work with a view to clearing up the numerous synonymical tangles in our Canadian species. The variability within the limits of a single species, the poor condition of much of the type material, and the failure of authors such as Taylor, Pearsall and Swett not only to recognize each other's species, but to realize the wide-spread distributiion of the individual species, hare all contributed to produce a muddle of specific names which has been almost impossible to unravel by a mere study of external characters.

Since the appearance of the article on the difficult truncata-citrata group of this genus by Swett (1917, Can. Ent., XLIX,, 64) and by Barnes and McDunnough (1917, Contr., III, (4), 227, Pls. XXI, XXX; 1918, Contri., IV, (2), 137) little has been published concerning the North American representatives with the exception of the addition of a couple of new form-names by Wright and Blackmore. In the European literature several important papers, however, dealing with the Palaearctic species of the genus, have appeared; chief among these is the very comprehensive Monograph of the Palaearctic Species by Dr. P. Heydemann (1929, Mitt. Munch. Ent. Gesells., 207-292, Pls. I-XV) copiously illustrated with figures of the adults and of the genitalia, both male and female.

AbstractThe late-instar larvae of about 185 species of the North American Olethreutidae are described and most of them illustrated. Included in these are many pests, such as Grapholitha molesta, Carpocapsa pomonella, and Spilonota ocellana on fruit trees, Paralobesia viteana on grapes, Ancylis comptana fragariae on strawberries, Laspeyresia nigricana in pea pods, Laspeyresia caryana in hickory and pecan nuts, Taniva albolineana in spruce needles, and species of Rhyacionia and Petrova on pines. Keys to species groups and to individual species are provided. Of the diagnostic and specialized characters listed, the most useful include the setae, the spinneret, and the shape of the larva, especially of its head and anal shield. The main characters are given for the postulated ancestral larva and for the highly developed larva. Most of the species groups are arranged according to the suggested phylogenetic relationship of their larvae, emphasizing the necessity of a revision of the family. Larvae of some genera previously difficult to classify, such as Pseudogalleria and Hystricophora, indicate the relationship of those genera to other groups; conversely, lack of relationship is clearly shown in other instances, e.g., between Carpocapsa pomonella and Carpocapsa saltitans, and between the two species Epiblema culminana and E. suffusana and other members of the genus Epiblema.

Abstract Canonical correlation analysis (CCA)-based statistical corrections are applied to seasonal mean precipitation and temperature hindcasts of the individual models from the North American Multimodel Ensemble project to correct biases in the positions and amplitudes of the predicted large-scale anomaly patterns. Corrections are applied in 15 individual regions and then merged into globally corrected forecasts. The CCA correction dramatically improves the RMS error skill score, demonstrating that model predictions contain correctable systematic biases in mean and amplitude. However, the corrections do not materially improve the anomaly correlation skills of the individual models for most regions, seasons, and lead times, with the exception of October–December precipitation in Indonesia and eastern Africa. Models with lower uncorrected correlation skill tend to benefit more from the correction, suggesting that their lower skills may be due to correctable systematic errors. Unexpectedly, corrections for the globe as a single region tend to improve the anomaly correlation at least as much as the merged corrections to the individual regions for temperature, and more so for precipitation, perhaps due to better noise filtering. The lack of overall improvement in correlation may imply relatively mild errors in large-scale anomaly patterns. Alternatively, there may be such errors, but the period of record is too short to identify them effectively but long enough to find local biases in mean and amplitude. Therefore, statistical correction methods treating individual locations (e.g., multiple regression or principal component regression) may be recommended for today’s coupled climate model forecasts. The findings highlight that the performance of statistical postprocessing can be grossly overestimated without thorough cross validation or evaluation on independent data.

Holorusia Loew, 1863 (Diptera: Tipulidae) is a relatively large crane fly genus with a wide distribution in the Afrotropic, Australasian–Oceanian, Eastern Palearctic, Oriental and Nearctic Regions. Although the genus is well known to include the largest crane fly species, the immature stages are, thus far, only described for the larva and pupa of the North American Holorusia hesperea Arnaud & Byers, 1990. In this study, we describe for the first time the egg, larva and pupae of the Japanese Holorusia mikado (Westwood, 1876). Larvae were collected from semi-aquatic habitats, from slow flowing areas of streams and small waterfalls where leaf litter accumulates; the larvae are detritivores and feed on wet, decomposing leaves. The larvae were reared to adults in the laboratory. Morphological characters of immature stages discussed with comparison with the North American H. hespera. Male and female genitalia are illustrated and described in detail for the first time.

Abstract The Euro-Siberian Scarce Fritillary Euphydryas maturna is considered a vulnerable species in the European Union and is listed in Annexes II and IV of the Habitats Directive. The butterfly shows a complex pattern of larval plant use throughout its range. In central Europe females oviposit on some trees and bushes, especially Fraxinus spp., on which hatched larvae spend their pre-diapause phase of development feeding gregariously in conspicuous webs. However, some herbal plants are also reported in the north and east. During a study performed in the Natura 2000 area “Dolina Biebrzy” (Biebrza Valley) in NE Poland we recorded populations showing a unique mixture of ecological characteristics. Both Fraxinus excelsior and Veronica longifolia were used as larval food plants before hibernation, and some local populations seemed to be completely dependent on the latter plant. Moreover, in the spring, at one site, we observed larvae feeding on Salix rosmarinifolia - the first host record for this plant species. The importance of our findings for conservation, as well as for the monitoring of the butterfly, is discussed.

Kribiodorum Kieffer, an otherwise North American and African genus of Chironomini (Diptera: Chironomidae), extends to the Oriental region through two new species. An adult male and female of Kribiodorum malicky sp. n. is newly described from Thailand, and from Brunei (Borneo) a pharate male and the pupa of Kribiodorum belalong sp. n. is described. Additionally, from Namibia (s.w. Africa) a 'manuscript' taxon is described formally with co-authorship of the late Arthur Harrison as Kribiodorum kunene sp. n. Males of the new species and the sole new pupa conform substantially to generic diagnoses based on the North American Kribiodorum perpulchrum (Mitchell). Examination of specimens of African Kribiodorum pulchrum Kieffer and N. American K. perpulchrum confirms their morphological similarity and reaffirms the junior synonymy of Stelechomyia Reiss designated for the North American species. Kribiodorum expands the number of genera of Chironomidae with African and Asian representatives, although unusual in its absence from Australia yet presence in the Nearctic.

The European Union since the 1990s has been engaged in a unique project of reducing mobility controls between members while strengthening the external borders and then shifting control outward. The individual pieces of the remote control strategies themselves are common, with the exception of the Frontex external border control coordinating agency, which does not have parallels in the North American or Australian cases. Europeanization has cross-cutting effects on remote control. The ubiquity of policies rooted in law, regulations, or formal agreements with other states—around readmission, visas, carrier sanctions, safe third countries, and safe countries of origin—is a result of Europeanization. However, Europeanization also includes built-in constraints derived from its supranational courts and institutions.

AbstractThe noctuid subfamily Heliothidinae, which is represented in North America by 158 species, is redefined, largely on the basis of male genitalic characters. Of genera included in the subfamily in McDunnough's 1938 check list, only four are recognized as valid, these being Heliothis Ochs., Schinia Hbn., Heliolonche Grt., and Melaporphyria Grt. Helicoverpa Hdwk., which was described subsequent to the appearance of McDunnough's list, and Protoschinia which is described as new here, are also included. Grotella Harv., Hemigrotella B. & McD., and Neogrotella B. & B. are not considered heliothidine genera and are removed to the Stiriinae.Eight genera, which have been assigned to the Amphipyrinae because they lack the mid and hind tibial setae characteristic of other heliothidine components, have also been incorporated in the Heliothidinae; these genera are Microhelia Hamp., Heliothodes Hamp., Baptarma Sm., Eutricopis Morr., Derrima Wlk., Erythroecia Hamp., Rhodoecia Hamp., and Pyrrhia Hbn. Because of the close similarity in structure and habits between these genera and those previously mentioned, the two groups are considered to constitute a monophyletic assemblage within the Noctuidae, despite the discrepancy with respect to mid and hind tibial setae.A key to the 14 North American genera of the Heliothidinae is presented. Descriptions of genera and figures of the male and female genitalia of the type species of all valid genera and of many genera in synonymy are provided. Canthylidia Butl. and Timora Wlk. are newly synonymized to Heliothis, and Heliosea Grt. to Heliolonche Grt. A check list of the North American Heliothidinae is appended to the text.The possible phylogenetic relationship of the Heliothidinae to the Stiriinae is discussed. The latter group is raised from tribal rank in the Amphypyrinae to subfamily rank; a number of genera are added to it, and a provisional redefinition of the subfamily is presented.
