History.—A species found in America ; most com- mon in southern states. Descriptio7i.—About the size of a honey-bee. Its body is black, covered with fine hair. The thorax is ornamented with longitudinal gray bands. The fe- male is provided with a cone-shaped ovipositor, with which she deposits her eggs, cementing them to the hair. Life Cycle.—The fly deposits its eggs upon the hair in the vicinity of the heel. From this point the larvae are taken into the mouth and become lodged in the mucous membrane of the oesophagus. The eggs are laid in summer ^i^- b-Hypoderma Lineata Larva. and the larvae are found in a, Dorsal view their most fully developed ^' '^^"^'"^^ ^'^^• stage in the oesophagus about November. At this time they are about five-eighths of an inch long. They now leave this locality and wander through the connective tissue to a position mider- neath the skin in the region of the back. Here.
