deposits its eggs in vessels containing vinous liquors, belongs 
to thissubgenus. We formerly referred it to Mosillus(1). 
* The Muscides of the three following divisions have an oblong 
body; the wings are incumbent and nonvibratile; the head, either 
rounded or almost spherical, or nearly pyramidal, or bordering on 
an oval, is plane above, prolonged and narrowed into a point, usually 
truncated or obtuse at its anterior superior extremity; and the face 
is covered with a white membrane, furrowed longitudinally on each 
side. The head is frequently compressed below the antenne, and 
its inferior or oral extremity projects in the manner of a truncated 
snout; in others, the face forms a strongly inclined plane, which is 
not (or almost not) turned up inferiorly. The antennz are inserted on 
the top of the front and sometimes even received in fossulx, but 
they most commonly project, are straight and distant, and in several 
as long as the head, or longer. In all the other Muscides, they are 
always shorter than the head. 
The Muscides of the fourth division, that of the ScaromyzipEs, 
as well as those of the fifth, are distinguished from the species of 
the sixth, by the following characters: the head, viewed from above, 
is never longer than it is broad, its form being nearly spherical or 
triangular; the posterior legs are never much longer than the body 
nor very slender, and the body, though sometimes narrow and elon- 
gated, is not filiform. 
Here, the Scatomyzides are distinguished from the Muscides of 
the following division, or the Dolichocera, by their antenne, of which 
the third joint is evidently longer than the preceding one; with the 
exception of a single genus, Loxocera, they are always shorter than 
the head. The anterior and superior extremity of this latter part 
of the body rarely projects beyond the eyes, and when viewed from 
beneath usually appears almost hemispherical, and rather wider 
than it is long. 
Sometimes the posterior legs are large and distant, their thighs 
are thick or compressed, and the joints of their tarsi dilated or 
widened. The antenne are always very short, with the last joint 
lenticular or nearly globular, and furnished with a simple seta. 
The sides of the face are pilose and silky. 
(1) It may perhaps be a Piophyla, Fall., a genus in which is placed the M7. 
casei, L., whose body is very black and glossy; epistoma, front and legs, fulvous; 
anterior legs and posterior thighs with a black ring.
