I know of no obser- vations, however, to establish such a means for tlieir distribution. In depositing its eggs it selects some wound or decaying matter and lays a mass of eggs at once; at least three or four hun- dred may be deposited by a single female within a space of a very few moments, and the same fly may oviposit at dift'erent times and in different places hundreds or even tlnmsands of eggs. The eggs are cylindrical, like those of other flies, about 1 mm. in length, white. 'Tmler the microscope the eggs show a prominent ridge on one side.'' (Weed.) The eggs hatch within a few lumrs. Francis says:. r I Flo. 05.—C inaecl- laria: lieail, side V i (• \v—ciilarguil (after Francis). My present opinion is tlint if tbo ejigs are laid in ii luniHt place and on a warm day it requires less than one. hour; whereas if laid in a dry place they Heeni to dry up and lose their vitality. Weed considers the time required for hatching about nine hours. The idea that they may be deposited in living condition is combated by all careful observations. The larva, or maggot, is a whitish footless grub, rather slender and (luite active, burrowing into the tissues of the aflected animal or into the mass of putrid flesh or decaying matter that furnishes it food. They grow rapidly and mature in Ave or six days (Weed) or about a week (Francis). When mature they escape from tlie wound they have infested or wriggle away from the mas
