ABSTRACT
The most familiar Lygaeidae, large species of Oncopeltus Stal, Lygaeus Fabricius, and related genera, are usually bright red or orange marked with black, white, or occasionally yellow. Members of other subfamilies are more somber, ranging from pale straw yellow through various browns to black. Many species have black, brown, or white markings, and a few have tinges of red. The wings, while usually fully developed, are often reduced in flightless morphs. Wing polymorphism is unrelated to sex in the Lygaeidae. Keys to genera of several subfamilies and tribes of Lygaeidae and to species of many genera are available; these are cited in the body of the catalog and listed in the references. The least obvious modification is termed sub-macroptery: the apparently normal heme-lytron is actually shorter than those of macropterous individuals. The bibliography lists all references cited in the catalog itself, and all references known to us to the Lygaeidae of America north of Mexico from 1964 through 1986.
