 domestica), III, C. G. Hewitt (Quart. Jour. Micros. Sci. [London], n. ser., 54 

 (1909), No. 215, pp. 3.'f7-41'h P'- i)- — This is the concluding paper of the series

The author shows the distribution of this fly to be world-wide. Nine species of 

 flies occurring as coinhabitants of houses with M. domestica or as visitants are 

 noted. Under the heading of physiology, the influence of food, temperature, 

 and light, hibernation, flight, and regeneration of lost pax'ts are discussed. The 

 natural enemies and occasional parasites considered are Cherncs nodosus, mites, 

 and Empusa musece. The true parasites include 2 flagellates (Herpetomonas 

 muscce-domesticw and Crithidia miiscw-domesticw) and a nematode (Habronema 

 musece. Mention is also made of the transmission of eggs of Twnia and Ascaris 

 sp. The pathogenic organisms disseminated by M. domestica and its nonblood- 

 sucking allies considered are those of typhoid fever, anthrax, cholera, tubercu- 

 losis, ophthalmia, plague, etc., a table being given which shows the source of 

 bacteria from flies. The larvje of M. domestica and its allies are shown to be 

 frequently the cause of intestinal myiasis and diarrhea in children. 



A list is given of 99 titles of the more important references and an account 

 of the breeding of J/, domestica during the winter is appended.
