Muscina stabulans is re- garded by Portschinsky (1913) as responsible for many of the cases of intesti- nal myasis attributed to other species. He records the case of a peasant who suffered from pains in the lower part of the breast and intestines, and whose stools were mixed with blood. From November until March he had felt particu- larly ill, being troubled with nausea and vomiting in addi- tion to the pain in his intestines. In March, his physician prescribed injections of a concentrated solution of tannin, which resulted in the expulsion of fifty living larvse of Muscina stabulans. Thereafter the patient felt much better, although he suffered from intestinal catarrh in a less severe form. Calliphorinse—Closely related to the Sarcophagidas are the CalliphorincB. to which group belong many of the so-called "blue bottle" flies. Their larvEe feed upon dead animals, and upon fresh and cooked meat. Those of Pro- tocalliphora, already mentioned, are ectoparasitic on living nestling birds. Larvae of Lucilia, we have taken fromtimiors on living turtles. To this sub-family belongs also Aucheromyia luteola, the Congo floor maggot. Some of thesey and at least the last mentioned, are confirmed, rather than faculat- tive parasites. Various species of Calliphorinas are occassionally met with as facultative parasites of man. Chrysomyia macellaria, the screw worm fly (fig. 107), is the fly which is responsible for the most serious cases of human myasis in the United States. It is widely distributed in the United States. 103. Lucilia cassar. (x3).
