The subfamily Museinse, however, embracing the house-flies, andother species equally obnoxious, forces itself more upon our consider-ation. The house-fly(Musca domestica) isknown by every onethe world over. It isa highly sociable in-sect, and clings tomankind with a te-nacity more to berepudiated than ad-mired. Its breedingplaces are aroundstables, and a femalewill lay from 120 to1B0 eggs.

Severebites, and sometimes poisonous ones, are inflicted by this insect, forwhich the house-fly gets the blame. The horn-fly (Hsematobia serrata) is another dipterous pest ofcattle. The screw-worm (Compsomyia macellaria), to which we have beforealluded, belongs also in this subfamily; as does the blowfly {Caliphoravomitoria), the largest of the common species, with a deep blue, almostblack body, always coming in swarms when there is an odor of cookingcabbage or decomposing meat.
