New Distribution Records of the Tiger-Moth Genus \u3ci\u3ePhragmatobia\u3c/i\u3e in North America (Lepidoptera: Arctiidae: Arctiinae)

New distribution records for all three Nearctic species of Phragmatobia include state records (the first records for the states indicated) of P lineata (Maryland, Wisconsin); P fuliginosa rubricosa (Ohio, South Dakota), and P assimilans (Idaho, Montana, Pennsylvania, Wisconsin), all representing southern range extensions at those longitudes except for the Wisconsin records of P lineata, which are northern range extensions. Chelone glabra (Scrophulariaceae) is reported as a larval hostplant of P lineata, and descriptive notes on the larva of this species are included. Midwinter activity of a larva crawling on snow is reported for P fuliginosa rubricosa. The rare original description of Phragmatobia dallii Packard, 1870, is reproduced

The Distribution of Three Broadly Sympatric Species of \u3ci\u3eSymmerista\u3c/i\u3e Moths (Lepidoptera: Notodontidae) in the Great Lakes and Midwest Regions of the United States.

All three superficially inseparable species of Symmerista known to occur in eastern North America are sympatric in, and reach their western limit of distribution in, the southern Great Lakes and Midwest Regions of the United States. In this region two of the species also reach their southern limit of distribution (S. canicosta reaches its southwestern limit in North Dakota, South Dakota, Missouri, Kentucky, and North Carolina; S. leucitys reaches its southwestern limit in North Dakota, Missouri and Kentucky). The third species (S. albifrons) reaches its northwestern limit in Michigan and Wisconsin. All three species are here documented from well beyond their previously reported ranges, and distribution maps are provided for them. Diagnostic male abdominal structures are figured. Larvae of Symmerista are frequently reported as defoliators of oak (Quercus), maple (Acer), and other hardwoods

Geron Calvus (Diptera: Bombyliidae), a Parasite of Solenobia Walshella (Lepidoptera: Psychidae) in Michigan

Excerpt: Very little is known of the biology of bee-flies in the genus Geron; the few available records show that the larvae are parasitic on Lepidoptera larvae. Mik (1896) noted that Geron gibbosus Meigen had been reared from larvae of the pyralid Nephopteryx sublineatella Strg. and the psychid Fumaria crassiorella (Bruand) in Europe, while Maxwell-Lefroy and Howlett (1909) recorded the tortricid Laspeyresia jaculutrix Meyrick as a host of Geron argentifrons Bru. in India. The present paper appears to be the first report on the biology of any North American Geron

Finite rank perturbations and solutions to the operator Riccati equation

We consider an off-diagonal self-adjoint finite rank perturbation of a self-adjoint operator in a complex separable Hilbert space $\mathfrak{H}_0 \oplus \mathfrak{H}_1$, where $\mathfrak{H}_1$ is finite dimensional. We describe the singular spectrum of the perturbed operator and establish a connection with solutions to the operator Riccati equation. In particular, we prove existence results for solutions in the case where the whole Hilbert space is finite dimensional.Comment: 13 pages, added Preliminaries, added more detail

Insects. Ross E. Hutchins. Englewood Cliffs, New Jersey: Prentice- Hall, Inc., 1966. xii, 324 pp. $6.95.

Excerpt: Contemporary entomological writing usually falls into one of two categories: general picture-books designed. for youngsters, and learned monographs and specialized publications that are generally unavailable and incomprehensible to the layman. Insects fills this gap, and interprets modern findings for the advanced amateur, the adult lay public, and even offers insights into aspects of entomology that a professional entomologist, devoted as he is to a specialized field, will find to be new and interesting

Wild Flowers of the United States: Volume 1, The North-Eastern States (in two parts). Harold William Rickett. New York: McGraw-Hill Book Company, 1966. x, 559 pp. $39.50.

Excerpt: Many entomologists are faced with the problem of identifying a plant that an insect has been gathering nectar from, feeding on, or pollinating. Unless he is armed with a working knowledge of botany, and can handle the cumbersome keys in our modern floras, h e must resort to a specialist or a picture book

New Records of Acrolophidae (Lepidoptera) from Kentucky

Excerpt: A recent collection of Kentucky moths submitted for identification contained 28 specimens of Acrolophs, or burrowing webworms. Rudolph A. Scheibner collected the moths in 1966 in Lexington, Fayette Co., and Paintsville, Johnson Co., Kentucky. The specimens are deposited in the insect collections of the University of Kentucky and Michigan State University. The five females in the series, all from Lexington (three collected on 19 June and two collected on 5 July), were not identified. The 23 males, identified according to Hasbrouck (1964), represent four species. Only one of them, A. popeanellus, has previously been recorded from Kentucky

The geography and co-location of European technology-specific co-inventorship networks

This paper contributes with empirical findings to European co-inventorship location and geographical coincidence of co-patenting networks. Based on EPO co-patenting information for the reference period 2000-2004, we analyze the spatial con figuration of 44 technology-specific co-inventorship networks. European co-inventorship (co-patenting) activity is spatially linked to 1259 European NUTS3 units (EU25+CH+NO) and their NUTS1 regions by inventor location. We extract 7.135.117 EPO co-patenting linkages from our own relational database that makes use of the OECD RegPAT (2009) files. The matching between International Patent Classification (IPC) subclasses and 44 technology fields is based on the ISI-SPRU-OST-concordance. We con firm the hypothesis that the 44 co-inventorship networks differ in their overall size (nodes, linkages, self-loops) and that they are dominated by similar groupings of regions. The paper offers statistical evidence for the presence of highly localized European co-inventorship networks for all 44 technology fields, as the majority of linkages between NUTS3 units (counties and districts) are within the same NUTS1 regions. Accordingly, our findings helps to understand general presence of positive spatial autocorrelation in regional patent data. Our analysis explicitly accounts for different network centrality measures (betweenness, degree, eigenvector). Spearman rank correlation coefficients for all 44 technology fields confirm that most co-patenting networks co-locate in those regions that are central in several technology-specific co-patenting networks. These findings support the hypothesis that leading European regions are indeed multi- filed network nodes and that most research collaboration is taking place in dense co-patenting networks. --Co-patenting,co-inventorship,networks,linkages,co-location,RegPAT

Geographic concentration and spatial inequality: Two decades of EPO patenting at the level of European micro regions

This paper contributes with empirical findings to the research on structural inequality and geographic concentration of European inventorship activity at the level of European micro regions. We analyze the spatial structure and dynamics of 43 technology fields (ISI-SPRU-OST concordance) and 6 high-technology fields based on data on EPO patent applications and EPO inventors for the reference period 1977-2004. Based upon OECD RegPAT database (January 2009), we extract EPO patent applications (fractional counting) and inventor IDs (full counting), which are spatially linked to 819 European micro regions (OECD TL3), covering the EU-25, Switzerland and Norway. Besides standard descriptives, we compute Herfindahl-Hirschman indices, location quotients and weighted locational and spatial GINI coefficients. We confirm the hypotheses that (i) the technology fields under analysis differ in their overall size with respect to the stock of EPO patent applications and inventors; (ii) the share of regions with LQ > 1 has decreased compared to the share of regions with at least a single patent application; (iii) the sample of European regions is characterized by highly concentrated and unequally distributed technology fields; (iv) spatial inequality of EPO patenting and inventor location has decreased significantly within the last two decades for most technology fields. In this respect, our quantitative approach clearly depicts dispersion tendencies and decreasing inequality, although structural dynamics differ between technology fields. --geographic concentration,RegPAT,EPO patenting,GINI coefficient,location quotient,inventorship,inequality
