Wound infection not rarely complicates the further course. The parasite should be removed by carefully Lifting it out with a dull forceps. FLY LARVAE (Maggots) Ply larvae are occasionally observed as parasites in man. The mother ani- mals belong to the family of oestrides or of the muscides, the actual flies. The clinical picture produced by Larvas is known as myiosis externa or interna 3. intestinalis. In Europe myiosis externa is mostly produced by the Larva of the muscides, more rarely by the Larva of oestrides. For the Latter the larva of the hypo- derma bovis, de Geer, or hypoderma diana, Brauer, are responsible. In the tropics the gadfly boil of man is due to the dermatobia noxialis, Brauer, or the ochromyia anthropophaga. As boob as the eggs of these flies have been depos- ited upon the skin, the Larvas pour forth, bore into the skin, and in the course of a few months cause the affection which is known as the "gadfly boil " of entile, of the Btag and of the roe. In cattle Larvae are taken up by the mouth and finally find their way under the skin: whether the Bame course is followed in man has Qoi vet been proven. Recovery occurs spontaneously, by the egress of the parasites, or by Burgical opening and extraction of the larva« from the carbuncle-like cutaneous swelling. Erautner observed a dipteren larva in an isolated Location. He extracted a larva of the hypoderma bovis from the anterior (handier of the eye.
