Type-locality: Minnesota, Anoka County, Moore's Lake. Moderate size (8 mm); dull yellow and black; frontoclypeus yellow, some specimens with small triangle of pol- len below antennae; frontal callus yellow, darkened above (in one specimen cal- lus wholly dark brown); black median stripes of abdomen joined on second tergite, sublateral stripes do not reach anterior margin of second tergite; wing membrane lightly tinted, pattern pale brown, not covering all of discal cell; hyaline triangle does not quite reach second longitudinal vein (Fig. 57). Male similar to female, but wing membrane, especially in anal area, more heavily tinted; apical spot slighdy broader; tri- angular poUinose area on frontoclypeus reaches halfway to level of frontoclypeal pits. The combination of a tinted wing membrane and brown wing pattern which does not completely cover the discal cell should separate this species from any other likely to be found in Illinois. The larva of this species is unknown. C. luteopennis is a rarely collected species of Chrysops known from only five localities in the north-central states and in southern Ontario (Fig. 133). Eventually it may be found in Illinois near Lake Rg. 133.—Distribution of Chrysops luteopennis in North America. Chrysops macquarti Philip Chrysops macquarti Phihp (1961:161). Type-locality: Maryland, Catonsville. Moderate size ( mm): yellow and black; frontoclypeus shining yellow; frontal callus black or dark brown; thorax greenish gray in ground color; scutellum usually with considerable yellow; abdomen with yellow median stripe between two black stripes of vary- ing width, laterally yellow; apical spot very broad (Fig. 58), extending into second posterior cell; hyaline triangle does not reach second longitudinal vein; crossband broad, covers discal cell, na
