This is a muscid of grewsome habits, which has a wide distribution throughout Africa.
In many of the muscid they form nearly a semicircle, or rather, perhaps, the quadrant of a sphere.
Distiproboscis: the outer third of the proboscis in muscid flies, bearing the labella.
In many flies (muscid) a vertical frontal cavity receives the antenn, which point downwards during repose.
The largest of the muscid found in Europe is Echinomyria grossa, which measures about three-quarters of an inch in length.
The larv described in Farres case, not being setose, must be referred to one or other of the muscid proper.
Basi-proboscis: basal third of the flexed proboscis of muscid flies.
Mediproboscis: the middle third of the flexed proboscis of muscid flies.
The larva or maggots (fig. 110) have the typical shape and actions of most maggots of the muscid group.
