Dr. Leconte informs us that his com-panions were not aware of the time Mhen the eggs of the larvae,obtained by him, were deposited in their bodies. He also statesthat the presence of the larva gave rise to comparatively littleuneasiness. According to Krefft a species of Batrachomyia is parasiticupon four species of Australian frogs. The larvae are foundbetween the skin and the flesh behind the tympanum ; they areof a yellow color and may be squeezed through a small open-ing that exists over them. When they quit the frog the latter. MUSCID^. 407 dies. The change to the pupa state is usually effected on thelowei- surface of a piece of rock in some damp locality.

The antenna are three-jointed, the terminaljoint being flattened and with a plumose bristle in the typicalspecies. The proboscis ends in a fleshy lobe, with porrectsingle-jointed maxillary palpi. The four longitudinal veins ofthe wing are simple ; the first of the two veins on the hinderedge often approaching that on the apex of the wing; the tarsihave two pulvilli, and the abdomen is five-jointed.
