 represented in most tropical and subtropical countries ; 

 one species occurring in the warmer parts of southern 

 Europe. The adults are usually very vicious biters, 

 both by day and night. According to the experiments 

 of the American Commission on Yellow Fever, S. fas- 

 ciata is the agent which spreads the germs of this dis- 

 ease. S. fasciata, Fabricius (1805), a very distinct and 

 common species, easily distinguished by the thoracic 

 ornamentation and by the last hind tarsal joint being 

 white. It is almost cosmopolitan, but does not appear 

 to occur in cold regions. It is one of the most trouble- 

 some and annoying mosquitos ; the bite is very irritat- 

 ing. Both male and female bite. It is the intermediate 

 host of the hematozoon Filaria Bancroftii, which also 

 occurs in Culex fatigans, Widemann, and in Anopheles. 

 The yellow fever parasite is disseminated by this gnat.

 mitting the outflow of the menstrual fluid and prevent- 

 ing the entrance of the spermatozoa. By removing
