FAMILY MUSCIDAE 



323 



the house fly, Musca domestica, L., and the tsetse fly, Gloss ina palpalis, 

 R-D. ; the former insect, in addition to causing great annoyance, is 

 able to contaminate food with pathogenic bacteria, and it has followed 

 man in his migrations all over the globe ; the latter transmits the 

 parasite of Sleeping Sickness, but is fortunately localized in its distribu- 

 tion. The Muscidae also include several veritable pests of the domesti- 

 cated animals, some of which carry dangerous parasites. Any one 

 who has observed a horse or a cow being attacked by hundreds of blood- 

 sucking muscids, such as Stomoxys, Lyperosia and Philaematomyia, will 

 realize the extent to which these animals are worried by such insects. 



Although man is not usually troubled by these smaller blood-sucking 

 muscids, there are others, the Calliphorinae, which have the habit of 

 depositing their eggs or larvae in his subcutaneous tissues or nostrils. 



The Muscidae which concern the worker may be grouped as follows ; it 

 should be understood, however, that this table is not meant to define 

 their exact genealogy, but rather to indicate their probable relationships.
