New and Little-Known Agromyzidae from Michigan (Diptera: Acalyptratae)

The latest major work on North American Agromyzidae, The Agromyzidae of Canada and Alaska (Spencer, 1969), lists 290 regional species. Of that number, half (147) are new species and 23 are previously described species newly recorded for the continent. It is thus evident that the North American Agromyzid fauna is still poorly known. Among material recently determined for the collection of Michigan State University, East Lansing, were the 5 additional new species herein described. A male allotype for Melanagromyza inornata Spencer (1969), described from the female only, is also described, and more detailed figures of the male postabdomen of Melanagromyza lauta Spencer (1969) are presented. Unfortunately all of the material is from random collecting and no host plants for the species are known. Types are retained in the collections of the United States National Museum of Natural History (USNM) and paratypes are returned to the Michigan State University collections (MSC)

A Review of the North American Species of the Genus Otites Latreille, with Descriptions of Two New Species (Diptera: Otitidae)

Excerpt: In 1961 (Steyskal, 1961), I placed the genus Otites in a key to the North American genera of Otitidae and indicated the synonymy of the genus Ortalimyia. Bibliography and synonymy of the hitherto known species of our area will be found in the Catalog of the Diptera of America North of Mexico (Stone et al., 1965). The only previously published key to our species was by Hendel (1911, as Ortalis), wherein were included Cevoxys latiusculus (Loew) and the four species now known as Otites bimaculahs (Hendel), 0. evythvocephala (Hendel), 0. pyvvhocephala (Loew), and O. stigma (Hendel). The present treat- ment excludes Cevoxys but includes O. snowi (Cresson) and two new species here described as O. evythvosceles and O. michiganus, making a total of seven species. The species form two rather distinct groups based on the width of the fronto-orbital pruinosity and the nature of the closure of the anal cell of the wing, as set forth in the following key. However, O. stigma (Hendel), while referable to the second group, shows characters indicating rapprochement to the first group. The generic name, although not found in large Greek lexicons, is of a form that corresponds to a rather large class of Greek nouns ending in -ites. As these words are all of masculine gender, it seems reasonable, in the absence of other decisive evidence, to treat Otites as masculine

The Flies of Western North America. F.R. Cole, with the collaboration of Evert I. Schlinger. Berkeley and Los Angeles: University of California Press, 1969. xi, 693 pp. $25.00.

Excerpt: Knowing of the excellence of the author\u27s work especially as an artist of Diptera, entomologists have been waiting for this much-needed volume since the completion of the first manuscript in 1932. The work deals with two-winged flies (Diptera) of North America west of the 104th meridian, south of the 70th parallel and north of Mexico, but including Baja California

Towards Querying in Decentralized Environments with Privacy-Preserving Aggregation

The Web is a ubiquitous economic, educational, and collaborative space. However, it also serves as a haven for personal information harvesting. Existing decentralised Web-based ecosystems, such as Solid, aim to combat personal data exploitation on the Web by enabling individuals to manage their data in the personal data store of their choice. Since personal data in these decentralised ecosystems are distributed across many sources, there is a need for techniques to support efficient privacy-preserving query execution over personal data stores. Towards this end, in this position paper we present a framework for efficient privacy preserving federated querying, and highlight open research challenges and opportunities. The overarching goal being to provide a means to position future research into privacy-preserving querying within decentralised environments
