REPORT of the COUNCIL. During the Session 1918-19 there have been seven ordinary evening meetings. The field meeting, arranged for June 28th, had to be abandoned as a visit to Hilbre Island, in the weather then prevailing, was quite impossible. On the invitation of Dr. Clubb a visit to the Museum was substituted. The communications made to the Society at the ordinary meetings have been representative of many branches of Biology, and the various exhibitions and demonstrations thereon have been of great interest. The meeting on Feb. 14th was held in conjunction with the Students' Branch and Prof. Herdman gave a lecture on " The Iguanodons of Bernissart." Owing to the difficulties created by the war it was impossible to secure a visiting lecturer, but the President filled the gap with a most interesting paper on " Vitamines in our Food." The Library continues to make satisfactory progress, and additional important exchanges have been arranged. The Treasurer's statement and balance sheet are appended. The members at present on the roll are as follows : Ordinary members 44 Associate members ... 13 Student members, including Students' Section, about 30 Total 87 ; SUMMARY OF PROCEEDINGS AT MEETINGS.

Information about the scientific collections is made available more and more often. The digitisation of such resources allows us to verify their value and share these records with other scientists – and they are usually rich in taxa and unique in the world. Moreover, such information significantly enriches local and global knowledge about biodiversi- ty. The digitisation of the resources of the Zoology Research Group, University of Silesia in Katowice (Poland) allowed presenting a substantial collection of scale insects (Hemiptera: Coccomorpha). The collection counts 9369 slide-mounted specimens, about 200 alcohol-preserved samples, close to 2500 dry specimens stored in glass vials and 1319 amber inclu- sions representing 343 taxa (289 identified to species level), 158 genera and 36 families (29 extant and seven extinct).

MALUMPHY &J.S.BADMIN 1The Food and Environment Research Agency, Sand Hutton, York YO41 1LZ, UK Email: [email protected] 2Coppice Place, Perry Wood, Selling, nr Faversham, Kent ME13 9RP ABSTRACT An annotated list of 79 species of Coccoidea (37 native, 16 naturalised introductions, 17 introduced species established on indoor plantings and 9 non- established introductions on growing plants), and 17 species of Aleyrodoidea (five native, six naturalised introductions, two introduced species established on indoor plantings and four non-established introductions on growing plants), recorded from Watsonian Kent is presented. The mealybug Balanococcus kwoni Pellizzari & Danzig, an Asian pest of bamboo, is recorded from Britain for the first time. Eleven species of scale insect and seven species of whitefly are recorded outdoors from Watsonian Kent for the first time. A third of all scale insect species and half the whitefly species found outdoors in Watsonian Kent are non-native introductions. None of the introduced species, however, appear to have any serious negative impact on native biodiversity, ecosystems, forestry or crops, although they do have an economic and aesthetic impact on ornamental plants in urban areas. Diaspidiotus pyri (Lichtenstein) has been recorded as an occasional, minor pest of apple; and the presence of non-native scales on ornamental plants has prevented the issuing of plant-passports for export. Naturalised non-native scale insect species are more abundant and frequently more damaging to ornamental plants in urban areas than native scale species.

  • Essay on the Prehistory of the Scale Insects ( Homoptera , Coccinea)
    POLSKA AKADEMIA NAUK INSTYTUT ZOOLOGII ANNALES ZOOLOGICI Tom 38 Warszawa, 30 V 1985 Nr 15 J a n K o t e j a Essay on the prehistory of the scale insects ( Homoptera, Coccinea ) Abstract. Coccids remained in the primary habitat — the forest litter — and retain­ ed the primary, seiniparasitic feeding behaviour much longer than any other Homoptera. Specialization to this habitat caused modifications of leg (one claw), wing shedding and lar- valization in female, dipterism, polymorphism and degeneration of male, and origin of resting stages in male ontogeny. Main radiation occurred also in this time. With the appearance of angiosperms, coccids became true parasites. Apterism in female directed their evolu­ tion towards sedentary life behaviour and development of protective systems. Fragility of male brought about diverse and elaborated chromosome systems. The combination of adaptation to soil habitat with specialization to parasitic life behaviour made the scale insects peculiar with respect to morphology and biology. The appearance of main radiations before acquisition of parasitic life habit resulted in morphological diversity, heterogenity of endosymbiotic systems and convergency of protecting devices. Various aspects of this hypothesis are discussed in the paper. CONTENTS I.

    BR. J. ENT. NAT. HIST., 23: 2010 243 SCALE INSECTS AND WHITEFLIES (HEMIPTERA: COCCOIDEA AND ALEYRODOIDEA) OF BEDFORDSHIRE C. MALUMPHY The Food and Environment Research Agency, Sand Hutton, York YO41 1LZ, UK [email protected] ABSTRACT This is the first account of the scale insects and whiteflies (Hemiptera: Coccoidea and Aleyrodoidea) of Bedfordshire, based primarily on samples collected by the author and records obtained from the Royal Horticultural Society. Collection details for 34 species of scale insect (27 native and naturalised species, seven introduced species established on indoor plantings) and eight species of whitefly (six native and naturalized, two introduced species established on indoor plantings) are provided. INTRODUCTION National and regional checklists are essential as baseline data from which faunistic changes due to factors such as climate change and international trade can be monitored and accurately assessed. The purpose of this communication is to record the scale insects and whiteflies (Hemiptera: Coccoidea and Aleyrodoidea) found in Bedfordshire (Watsonian Vice County 30), based primarily on samples collected by the author and unpublished records obtained from the Royal Horticultural Society (RHS). The latter records are mostly based on samples submitted by RHS members to the RHS Advisory Services for identification. A small number of samples were collected by the Plant Health and Seeds Inspectorate (PHSI) of Defra during statutory plant health inspections at commercial nurseries, and a few records were received in response to an illustrated article on the scale insects of Bedfordshire posted on the Bedfordshire Natural History Society (BHNS) website in June 2009 (http://www.bnhs.org.uk/).

A zoogeographical analysis of the scale insect (Hemiptera, Coccoidea) fauna of Fennoscandia and Denmark. Norwegian Journal of Entomology 60, 81–89. This paper presents the results of a zoogeographical analysis of the scale insects from the following countries: Sweden, Denmark, Norway and Finland. The number of species collected so far is 92 in 49 genera. The fauna is divided into the following zoogeographical groups: Palearctic, 56.5%, Holarctic, 18.5%, species from 2–3 zoogeographic regions, 10.9%. and Cosmopolitan, 14.1%. The connections between adjacent countries are also discussed. Key words: Scale insects, Coccoidea, zoogeography, Fennoscandia, Denmark. Carl-Axel Gertsson, Murarevägen 13, SE-227 30 Lund, Sweden. E-mail:[email protected] Introduction Studies in zoogeography have never been presented. In other parts of the world, however, According to the Database of the Scale Insects zoogeographical investigations of scale-insects of the World ScaleNet (Ben-Dov et al. 2012), have been studied by several authors. Data there are approximately 8000 described spec- covering the whole of the Palearctic region ies of scale insects worldwide. The scale was given by Bodenheimer (1934), Kozár & insects include all members of the superfamily Drosdják (1986), Kozár (1995b), Ben-Dov Coccoidea (Hemiptera: Sternorrhyncha), which (1990), the Middle-East, Ben-Dov (2011-2012), consists of 49 families (Ben-Dov et al. 2012).

    AMERICAN MUSEUM NOVITATES Number 3812, 36 pp. August 29, 2014 Morphology of the males of seven species of Ortheziidae (Hemiptera: Coccoidea) ISABELLE M. VEA1 ABSTRACT Because adult male Coccoidea rarely live more than three or four days, they are seldom collected and their morphology has been little studied. Therefore, the systematics of the Coc- coidea is dependent on the morphology of the paedomorphic adult female. A good example is the family Ortheziidae, in which the males of only four extant and three fossil taxa are known among more than 200 species. The present work provides descriptions of the male morphology of seven further species: Graminorthezia graminis (Tinsley), Insignorthezia insig- nis (Browne), Newsteadia americana Morrison, Orthezia annae Cockerell, O. newcomeri Mor- rison, and Praelongorthezia praelonga (Douglas), as well as another belonging to an undetermined genus. The males of three additional genera are added to the previous litera- ture on male Ortheziidae, providing significantly better sampling of male morphological variation within this family. Variation among genera confirms the latest classification of Kozár, in which Graminorthezia, Insignorthezia, and Praelongorthezia are separated from Orthezia. The use of confocal microscopy for the study of uncleared slide preparations is discussed as it allowed better visibility of macrostructures, although minute structures such as pores could not be thoroughly observed. An identification key to the species of known male Ortheziidae is included. INTRodUCTioN The Ortheziidae or ensign scale insects are a relatively small family within the scale insects (Hemiptera: Coccoidea) with 206 species (Miller et al., 2013) that are found pri- 1 Richard Gilder Graduate School, Division of Invertebrate Zoology, American Museum of Natural History, New York.
