Archive image from page 344 of Diptera Danica genera and species Diptera Danica: genera and species of flies hitherto found in Denmark dipteradanicage02lund Year: 1907 Dolichopodidae. 337 angulary lobe and a well developed inner part, the fringes of both of almost the same length. The developmental stages are not known. The species of Scellus are rather characteristic flies; they seem to be somewhat different with regard to occurrence; they may be found on commons at the shore in grass and low herbage at water pools, but also quite inland and on dry fields, as remarked under notatus. Aldrich says with regard to the American species (Entom. News, 1907, 133) that they are never seen at water, but are found on bark of trees, on the ground, or in grass, and he adds, '(exceptio- nally perhaps on stones)'. This does not hold good with regard to the European species, at all events not as far as concerns notatus, and Zetterstedt says about spinimanus 'in pratis humidis', and also gallicanus Beck, is by the author recorded to occur: 'am Rande mooriger Stellen'. It is however rather curious that 1 have taken notatus in so very different localities, and it seems to show that they are not bound to humid places. Of the genus 4 species are known from the palsearctic region; one occurs in Denmark. 1. S. notatus Fabr. 1781. Fabr. Spec. Ins. II, 448, 65 {Musca), et 1805. Syst. Antl. 269, 10 (Dolichopus). — 1824.
