Lipolexis

description: Lipolexis Förster, 1862
Lipolexis Förster, 1862: 249. Type species: Lipolexis gracilis Förster, 1862, by original designation.
Gynocryptus Quilis, 1931: 28. Type species: Gynocryptus pieltaini Quilis, 1930, by original designation and monotypy.
Type species. Lipolexis gracilis Förster, 1862, by original designation.
Type information. Holotype female, ZMHB. Country of type locality: Germany.
Diagnosis. Lipolexis gracilis has a petiole with central bifurcating carinae, a feature that positions it within the ‘ gracilis ’ species-group. It possesses maxillary palps with four palpomeres, labial palps with one palpomere (as in L. pelopsi). However, it differs from the latter by a less pubescent body and elongated petiole (proportions between length and maximum width of petiole at spiracles, 3.0– 3.6 in L. gracili s (2.4–2.6 in L. pelopsi )).
Biology. Lipolexis are solitary koinobiont endoparasitoids of aphids (Aphididae).
Molecular data. There are 495 DNA-barcode compliant sequences of Lipolexis in BOLD representing 28 different BINs, five species are also represented by seven other gene fragments (12S, 16S, 18S, 28S, 5.8S, ATPASE 6, and NADH), and one species, L. gracilis, by 2590 UCE loci (276.6 million bases) in the NCBI (https://www.ncbi. nlm.nih.gov/) sequence read archive (SRA).
Note. This genus appears to have its origins in the Oriental and Palaearctic regions (Kocić et al., 2020), and records from Australasia, the Nearctic, and Neotropics are due to deliberate introductions.

description: Angle-resolved photoemission spectra of a monolayer of Yb on W(110) reveal energy splittings and dispersion of the Yb 4f states that are obviously due to their hybridization with W-derived valence bands. These effects occur at well defined points of the surface Brillouin zone although a smearing over reciprocal space is expected from the structural incoherence of the Yb and W lattices. We conclude therefore that dispersion is not related to the periodic arrangement of the $4f$ states but reflects the k-dependent interaction of a single Yb 4f impurity with W bands.

Conversion from Conventional to Biological Dairy Farming: Sustainability Aspects from a Farm Modelling Perspective

description: In this paper the central issue is to quantify economic and environmental consequences for dairy farms when converting to biological dairy farming. A linear programming model is used to model a typical extensive and intensive dairy farm in The Netherlands. From the results it appears that extensive farms benefit from conversion while intensive farms lose income. Environmental consequences are quite diverse. The nitrogen surplus after conversion is much lower than before while ammonia emission is higher after conversion due to a higher number of animals. On the extensive farm the phosphate surplus is much higher after conversion due to the fact that a shortage of nitrogen in the biological situation can only be made up by applying animal manure (slurry) from other farms with consequential overfertilization of phosphate. When environmental legislation is introduced, biological farms appear to lose more income than conventional farms.

Low-Mass and Metal-Poor Gamma-Ray Burst Host Galaxies
Creators: name: Savaglio, Sandra

Subjects: subject: Astrophysics (astro-ph)

description: Gamma-ray bursts (GRBs) are cosmologically distributed, very energetic and very transient sources detected in the gamma-ray domain. The identification of their x-ray and optical afterglows allowed so far the redshift measurement of 150 events, from z = 0.01 to z = 6.29. For about half of them, we have some knowledge of the properties of the parent galaxy. At high redshift (z > 2), absorption lines in the afterglow spectra give information on the cold interstellar medium in the host. At low redshift (z < 1.0) multi-band optical-NIR photometry and integrated spectroscopy reveal the GRB host general properties. A redshift evolution of metallicity is not noticeable in the whole sample. The typical value is a few times lower than solar. The mean host stellar mass is similar to that of the Large Magellanic Cloud, but the mean star formation rate is five times higher. GRBs are discovered with gamma-ray, not optical or NIR, instruments. Their hosts do not suffer from the same selection biases of typical galaxy surveys. Therefore, they might represent a fair sample of the most common galaxies that existed in the past history of the universe, and can be used to better understand galaxy formation and evolution.

description: A ground-breaking initiativefor planning and action across borders of provincial legislature is operating in the arid Lake Eyre Basin of central Australia. The basin, which covers 16% of Australia’s land area, was considered for World Heritage listing by the A ustralian government in the early nineties because of its unique inland river systems and wetlands. Strong opposition to World Heritage listing from pastoralists and other stakeholders catalysed an alternate voluntary and community based initiative aimed at changing to more sustainable use of natural resources, a catchment management framework. Natural resource management and planning based on river catchments takes into consideration all environmental and production values. Activities of the groupfeature training of group members, initiation of on-ground projects through partnerships, coordination of research and the preparation of common maps and data sets. Sustainability will be achieved by building knowledge, better decision-making, changed management practices and building a sense of community across borders. Key success characteristics include the involvement of all interest groups (stakeholders) from the beginning of the process and initiation of the process by the community as opposed to the government. Other factors were the employment of an effective coordinator, a skills-based coordinating group drawn from all stakeholders, delegation offunding and power to catchment committees, strong support from the private sector, and significant funding from the Australian government.

description: The perturbative effective potential V in the massless $λϕ^4$ model with a global O(N) symmetry is uniquely determined to all orders by the renormalization group functions alone when the Coleman-Weinberg renormalization condition $\frac{d^4V}{dϕ^4}|_{ϕ= μ} = λ$ is used, where $μ$ represents the renormalization scale. Systematic methods are developed to express the n-loop effective potential in the Coleman-Weinberg scheme in terms of the known n-loop minimal subtraction (MS) renormalization-group functions. Moreover, it also proves possible to sum the leading- and subsequent-to-leading-logarithm contributions to V. An essential element of this analysis is a conversion of the renormalization group functions in the Coleman-Weinberg scheme to the renormalization group functions in the MS scheme. As an example, the explicit five-loop effective potential is obtained from the known five-loop MS renormalization group functions and we explicitly sum the leading logarithm (LL), next-to-leading (NLL), and further subleading-logarithm contributions to V. Extensions of these results to massless scalar QED are also presented. Because massless scalar QED has two couplings, conversion of the RG functions from the MS scheme to the CW scheme requires the use of multi-scale renormalization group methods.

Lyman alpha Radiative Transfer in Cosmological Simulations using Adaptive Mesh Refinement

description: A numerical code for solving various Lyman alpha (Lya) radiative transfer (RT) problems is presented. The code is suitable for an arbitrary, three-dimensional distribution of Lya emissivity, gas temperature, density, and velocity field. Capable of handling Lya RT in an adaptively refined grid-based structure, it enables detailed investigation of the effects of clumpiness of the interstellar (or intergalactic) medium. The code is tested against various geometrically and physically idealized configurations for which analytical solutions exist, and subsequently applied to three "Lyman-break galaxies", extracted from high-resolution cosmological simulations at redshift z = 3.6. Proper treatment of the Lya scattering reveals a diversity of surface brightness (SB) and line profiles. Specifically, for a given galaxy the maximum observed SB can vary by an order of magnitude, and the total flux by a factor of 3 - 6, depending on the viewing angle. This may provide an explanation for differences in observed properties of high-redshift galaxies, and in particular a possible physical link between Lyman-break galaxies and regular Lya emitters.

description: The bacterial flagellum and the related virulence-associated injectisome system of pathogenic bacteria utilize a type III secretion system (T3SS) to export substrate proteins across the inner membrane in a proton motive force-dependent manner. The T3SS is composed of an export gate (FliPQR/FlhA/FlhB) located in the flagellar basal body and an associated soluble ATPase complex in the cytoplasm (FliHIJ). Here, we summarise recent insights into the structure, assembly and protein secretion mechanisms of the T3SS with a focus on energy transduction and protein transport across the cytoplasmic membrane.

description: We explore the pulsationally driven orbital mass ejection mechanism for Be star disc formation using isothermal, 3D magnetohydrodynamic (MHD) and hydrodynamic simulations. Non-radial pulsations are added to a star rotating at 95\% of critical as an inner boundary condition that feeds gas into the domain. In MHD, the initial magnetic field within the star is weak. The hydrodynamics simulation has limited angular momentum transport, resulting in repeating cycles of mass accumulation into a rotationally-supported disc at small radii followed by fall-back onto the star. The MHD simulation, conversely, has efficient (Maxwell $α_{\rm M}$ $\sim$ 0.04) angular momentum transport provided by both of turbulent and coherent magnetic fields; a slowly decreting midplane driven by the magnetorotational instability and a supersonic wind on the surface of the disc driven by global magnetic torques. The angle and time-averaged properties near the midplane agree reasonably well with a 1D viscous decretion disc model with a modified $\tildeα=0.5$, in which the gas transitions from a subsonic thin disc to a supersonic spherical wind at the critical point. 1D models, however, cannot capture the multi-phase decretion/angular structure seen in our simulations. Our results demonstrate that, at least under certain conditions, non-radial pulsations on the surface of a rapidly rotating, weakly magnetized star can drive a Keplerian disc with the basic properties of the viscous decretion disc paradigm, albeit coupled to a laminar wind away from the midplane. Future modeling of Be star discs should consider the possible existence of such a surface wind.

description: The paper focuses on Pier Paolo Pasolini's pictorial practice and its continuity with the cinematographic image. Particular importance is given to the pictorial nucleus preserved at the Centro Studi in Casarsa della Delizia consisting of nineteen paintings made between 1941 and 1947 when Pasolini was a student of Roberto Longhi. Observing them reveals the artist's tendency to leave faces incomplete while giving them strong expressiveness. Thus, in his pictorial practice, Pasolini also confirms his search for balance between documentation and self-expression. keywords | Pasolini’s painting; self portrait; unfinished; facial expression; photography.

description: A series of numerical simulations on magnetorotational core-collapse supernovae are carried out. Dipole-like configurations which are offset northward are assumed for the initially strong magnetic fields together with rapid differential rotations. Aims of our study are to investigate effects of the offset magnetic field on magnetar kicks and on supernova dynamics. Note that we study a regime where the proto-neutron star formed after collapse has a large magnetic field strength approaching that of a ``magnetar'', a highly magnetized slowly rotating neutron star. As a result, equatorially-asymmetric explosions occur with a formation of the bipolar jets. Resultant magnetar's kick velocities are $\sim 300-1000$ km s$^{-1}$. We find that the acceleration is mainly due to the magnetic pressure while the somewhat weaker magnetic tension works toward the opposite direction, which is due to stronger magnetic field in the northern hemisphere. Noted that observations of magnetar's proper motions are very scarce, our results supply a prediction for future observations. Namely, magnetars possibly have large kick velocities, several hundred km s$^{-1}$, as ordinary neutron stars do, and in an extreme case they could have those up to 1000 km s$^{-1}$.

description: The Property Management Planning (PMP) campaign in Australia is a major government initiative, aimed at improving the financial and resource management sustainability of agriculture, that has been running since 1992. The basis of the campaign since 1995 has been the provision of an integrated, whole-of-system, eight workshop series to groups of five to ten participating families. This paper reports on an evaluation of the outcomes of the program in the slate of Queensland, where the program has the generic title of'FutureProfit. The evaluation study was based on individual, semi-structured interviews with 46 participants from 23 families in the first four groups to complete the program, in southern and central Queensland. All families and individuals believed they had benefited from the program, through enhanced sensitivity to natural resource management issues, improvements to their business management knowledge, analysis, and planning skills, and through exposure to experts infields such as accounting, banking, and law. Many also reported social benefits including improved communication within families, and between families within groups. Realisation of commonality of problems was leading to group approaches to solutions, such as shared input-purchase and labour-hire schemes. Success of the program is attributed at least partly to the adult education principles it incorporates. The PMP/FutureProfit program is making a positive contribution to sustainable farming in Queensland, because it is able to address, through its holistic approach, ecological, economic, and social dimensions of sustainability.

The evolution of an artist’s life and work, being a personal and reflective journal
Creators: name: Stanbridge, Harry Andrew
Publisher: name: University of British Columbia
Year: 2010

description: This personal and reflective journal concerns itself with the evolution of an artist's life and work specifically as it relates to those forces that determine the individual's philosophic perspective, as well as shape the form and content of his art. Three distinct yet related aspects of the artist's life were analyzed by using slides of the artist's paintings that were produced in the relevant periods. Christian conversion and its subsequent effect on the artist's life and philosophy were the first consideration. An analysis is done of the work leading to the conversion showing the effect on the artist of influential local and international artists. As well, the role of literary ideas as a stimulus for visual expression is touched upon. The nature of form and content, as it manifests itself in the paintings done during the conversion period and afterward, is examined in an attempt to show a resolution of style in the artist's work. The second area of reflective inquiry was the role of the artist as a teacher of art at the secondary level. Teaching and working in different mediums in the classroom situation were looked at to see what influence, if any, they had on the artist's attitude to form and content in his own work. The general demands of teaching, apart from the discipline of art, are considered as they relate to the pressures of time and their importance in the production of the artist's work. The third area relates to the first as it parallels and evolves out of the philosophic perceptions of the artist and their relationships to his public. Throughout the journal and in the analysis of the slides, close attention is paid to style, that is, the form the content takes and whether or not the artist's intent has been realized, in making his art visually accessible. The text is an exegetical account of the slides and it is recommended that it be read in conjunction with the projected slide images of the author's work.
Modelling the Relationships Between Farmers' Objectives and the Decisions Related to the Stocking Rate in Beef Production Systems of Central Brazil

description: In Central Brazil, the sustainability of beef cattle systems is under threat. More than half the 50 million ha of sown pastures are suffering from degradation. Overgrazing is one of the main causes, and therefore choice of the stocking rate is a crucial decision taken by the farmers. Hypotheses to explain the overgrazing paradox have been explored by a model where 'cattle ownership' and ‘economic returns' were optimized individually and then simultaneously, using Multi-period Linear Programming and Compromise Programming techniques. Different scenarios based on farmers' attitudes towards overgrazing, pasture costs and capital availability were analysed. In some cases, benefits from holding more cattle can compensate for the increasing costs of maintaining pastures - an observation that undermines the hypothesis that farmers practise overgrazing because they are unaware or uncaring about overgrazing costs. An appropriate approach to the problem of pasture degradation requires information on the economy of a wide range of pasture recovery and maintenance methods, accepting that some level of overgrazing could be rational.

D-brane instantons and the effective field theory of flux compactifications
Creators: name: Uranga, Angel M.

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We provide a description of the effects of fluxes on euclidean D-brane instantons purely in terms of the 4d effective action. The effect corresponds to the dressing of the effective non-perturbative 4d effective vertex with 4d flux superpotential interactions, generated when the moduli fields made massive by the flux are integrated out. The description in terms of effective field theory allows a unified description of non-perturbative effects in all flux compactifications of a given underlying fluxless model, globally in the moduli space of the latter. It also allows us to describe explicitly the effects on D-brane instantons of fluxes with no microscopic description, like non-geometric fluxes. At the more formal level, the description has interesting connections with the bulk-boundary map of open-closed two-dimensional topological string theory, and with the $\NN=1$ special geometry.

description: Norwegian farmers have in recent years established many different types of small-scale cooperation. The author of this paper has been working on a project called “Rural Cooperation at the Turn of the Century”, which received support from the Norwegian Ministry of Agriculture. The project’s goal was to increase farmers’ and advisers’ competence, and inspire them to increased cooperation. This presentation shortly describes the various forms of cooperation which at present are most common in Norwegian agriculture. Some advantages and disadvantages of cooperative measures will also be discussed. Many of the disadvantages of cooperation can be reduced by thorough planning andformalization of the planned cooperation. Various organizational forms will be discussed. It is also important to develop an advisory system that can assist in the establishment of new meastires, and follow up existing ones. Often, networking of similar cooperation schemes can be useful.

description: The forward fitting of solar flare observations with radiation-hydrodynamic simulations is a common technique for learning about energy deposition and atmospheric evolution during these explosive events. A frequent spectral line choice for this process is Ca II 854.2 nm due to its formation in the chromosphere and substantial variability. It is important to ensure that this line is accurately modeled to obtain the correct interpretation of observations. Here we investigate the importance of photoionisation of Ca II to Ca III by the hydrogen Lyman transitions; whilst the Lyman continuum is typically considered in this context in simulations, the associated bound-bound transitions are not. This investigation uses two RADYN flare simulations and reprocesses the radiative transfer using the Lightweaver framework which accounts for the overlapping of all active transitions. The Ca II 854.2 nm line profiles are found to vary significantly due to photoionisation by the Lyman lines, showing notably different shapes and even reversed asymmetries. Finally, we investigate to what extent these effects modify the energy balance of the simulation and the implications on future radiation-hydrodynamic simulations. There is found to be a 10-15% change in detailed optically thick radiative losses from considering these photoionisation effects on the calcium lines in the two simulations presented, demonstrating the importance of considering these effects in a self-consistent way.

description: The Sao Paulo State Watershed Program was drawn with multiple objectives to be optimized through planning of sustainable agricultural activities. Important dimensions that must be considered in implementing this program are farmer’s specific objectives and farm restrictions. This work presents a method for planning land use in a sustainable way, using Lexicographic Goal Programming to plan the mix of activities for each farm. These objectives are: minimization of runoff effects, pesticide use, seasonal income variability, and seasonal demand for labor; and maximization of farm gross margin, basic staple production, and resident labor use. The optimization process pointed to activities that affected the farm system (crop layout, labor, machinery, and pesticides use, gross margins, staple production, and soil conservation) in different ways. More acceptable solutions to farmers ’ multiple objectives were suggested through the planning land use.

New record for Vietnam.
Ecology
Collected in rubber plantations, at elevations from 175 to 896 m.
Comments
This record in southern Vietnam is the second in the Indochinese Peninsula, besides its recent collection in Singapore (Wang et al. 2022). Given the widespread distribution of this Afrotropical tramp species across almost all biogeographic realms, and its presence from India to Japan in the north, and from Indonesia (Lesser Sunda Islands) to the Solomon Islands in the south, this new record is not surprising. It also indicates the possibility of its presence in nearby countries such as Laos, Cambodia, Thailand and Myanmar, and Guangxi and Hainan provinces of mainland China.

description: Possible deviations from linearity of the LMC Cepheid PL and PLC relations are investigated. Two datasets are studied, respectively from the OGLE and MACHO projects. A nonparametric test, based on linear regression residuals, suggests that neither PL relation is linear. If colour dependence is allowed for then the MACHO PL relation is found to deviate more significantly from the linear, while the OGLE PL relation is consistent with linearity. These finding are confirmed by fitting "Generalised Additive Models" (nonparametric regression functions) to the two datasets. Colour dependence is shown to be nonlinear in both datasets, distinctly so in the case of the MACHO Cepheids. It is also shown that there is interaction between the period and colour functions in the MACHO data.

description: We discuss the prospects for identifying nearest isolated black holes (IBHs) in our Galaxy. IBHs accreting gas from the interstellar medium (ISM) likely form magnetically arrested disks (MADs). We show that thermal electrons in the MADs emit optical signals through the thermal synchrotron process while non-thermal electrons accelerated via magnetic reconnections emit a flat-spectrum synchrotron radiation in the X-ray to MeV gamma-ray ranges. The Gaia catalog will include at most a thousand of IBHs within $\lesssim 1$ kpc that are distributed on and around the cooling sequence of white dwarfs (WDs) in the Hertzsprung-Russell diagram. These IBH candidates should also be detected by eROSITA, with which they can be distinguished from isolated WDs and neutron stars. Followup observations with hard X-ray and MeV gamma-ray satellites will be useful to unambiguously identify IBHs.

description: I examine some properties of the overlap operator in the Schroedinger functional formulated by Luescher at perturbative level. By investigating spectra of the free operator and one-loop coefficient of the Schroedinger functional coupling, I confirm the universality at tree and one-loop level. Furthermore, I address cutoff effects of the step scaling function and it turns out that the lattice artifacts for the overlap operator are comparable with those of the clover actions.

Sustainable Agriculture Initiatives in New Zealand

Year: 1999
Subjects: Environmental Economics and Policy

description: The promotion of sustainable land management practices by central and regional government and through local community group approaches in New Zealand is summarised in this paper. There are constraints to farm level adoption of new sustainable technologies and management practices in NZ pastoral agriculture. Sustainable systems by definition should be environmentally safe, economically viable and socially and culturally acceptable. The lack of farm profitability, the lack of co-ordination of technology transfer providing information for decision making and the withdrawal of rural services were identified as constraints to the uptake of '‘sustainable systems”. For a period of 3-5 years a family owned farm received community and scientific input on how best to implement management and land use changes that will enhance sustainability. Both scientist and community group members raised their awareness of environmental, economic and social sustainability and the linkages between each aspect.

A public recreation planning model based on current recreation theory
Creators: name: Nichols, Thomas Matthew
Publisher: name: University of British Columbia
Year: 2010

description: The basic question facing recreation planners is: how much and what kinds of recreation opportunities should public agencies provide? This thesis attempts to answer this question by examining recreation theory in order to determine just what it is that public recreation is expected to accomplish. Early recreation theories, while they provided an answer in the form of nationwide standards, were found to be too simplistic. More recent theories, particularly those based on humanistic philosophy or "recreational need", are too open ended to give any qualitative or quantitative guidance to the public recreation planner. In order for it to be worthwhile for society generally to provide recreation opportunities, society generally must benefit. For this reason, theories based on the individual (humanistic theories) are unsatisfactory as a sole basis for recreation planning. It appears that it is not possible to take a purely positivistic approach to recreation planning at the present time because too little is known about what recreation (or its absence) does to an individual to be able to determine how much is enough. It is concluded that until such time as the necessary information on the effects of recreation is forthcoming, normative approaches employing community values will be necessary. In the first part of the thesis a recreation planning model is developed. The model begins with community values, as expressed through public participation, in the form of goals. The goals are then converted via objectives into facilities and programs. The recreation opportunities thus provided produce personal satisfactions and social benefits. The latter are compared with the original goals to determine the effectiveness of the recreation program (program evaluation). In Part II the Planning Model is compared with current recreation planning practice, as exemplified by the Vancouver (B.C.) Master Plan for Parks and Recreation. The following significant differences are noted: 1) the model is devoted to fulfilling long-term goals while the Master Plan emphasizes meeting demand for facilities and programs 2) the model relies on citizen input for direction while the Master Plan places greater emphasis on professional judgment 3) The Model requires a commitment to program evaluation and ongoing planing while the Master Planning process is oriented toward the production of a single end product. These differences imply that implementation of the Planning Model will require a significant amount of effort on the part of the community in terms of choosing the right planning techniques, committing sufficient resources, and developing the necessary political will power. It is hoped that recreation planners will find the Model sufficiently compelling Intellectually to go to the effort that its implementation will entail.
Asymmetric invasion in anisotropic porous media

description: We report and discuss, by means of pore-scale numerical simulations, the possibility of achieving a directional-dependent two-phase flow behaviour during the process of invasion of a viscous fluid into anisotropic porous media with controlled design. By customising the pore-scale morphology and heterogeneities with the adoption of anisotropic triangular pillars distributed with quenched disorder, we observe a substantially different invasion dynamics according to the direction of fluid injection relative to the medium orientation, that is depending if the triangular pillars have their apex oriented (flow-aligned) or opposed (flow-opposing) to the main flow direction. Three flow regimes can be observed: (i) for low values of the ratio between the macroscopic pressure drop and the characteristic pore-scale capillary threshold, i.e. for p0/pc < 1, the fluid invasion dynamics is strongly impeded and the viscous fluid is unable to reach the outlet of the medium, irrespective of the direction of injection; (ii) for intermediate values, 1 < p0/pc < 2, the viscous fluid reaches the outlet only when the triangular pillars are flow-opposing oriented; (iii) for larger values, i.e for p0/pc > 2, the outlet is again reached irrespective of the direction of injection. The porous medium anisotropy induces a lower effective resistance when the pillars are flow-opposing oriented, suppressing front roughening and capillary fingering. We thus argue that the invasion process occurs as long as the pressure drop is larger then the macroscopic capillary pressure determined by the front roughness, which in the case of flow-opposing pillars is halved.

 Syntype
KENYA • ♀; “Maü escarpment, á Molo, altitude de 2.420 m., 2 décembre 1911, st. no 19” (Kieffer 1913b: 13); MNHN EY25359, EY22427, EY22428.  Distribution
Afrotropical.  Comments
 Kieffer (1913) described Ceraphron alticola from a female specimen or specimens, though this is the only type known for this species to date. At this point, we consider this specimen to be a syntype. There are no original locality or type labels with the specimen, though there is a note reading “ Ceraphron alticola || Type 19 K.”. The same type number appears on the label for Aphanogmus fumipennis (vial MNHN EY25361), originally the type of Kieffer’s Ceraphron oriphilus.
Dessart dissected this specimen in 1966 and made two microscope preparations (prép. no. 6505/183), one of the right antenna (MNHN EY22427) and one of the right forewing (MNHN EY22428). The specimens are circled in black to indicate their position on the slides. The rest of the female specimen is in ethanol (vial MNHN EY25359).
