A Monograph of Egyptian Diptera. 



si>ecies new to Egypt, as wcU as to correct certain errors in tlic 

 literature concerning tlie previously kiiowii forms. 



In conclusion sonie référence slionld hc niailc to wiiat is incant 

 hy the term «Egyptian" in tliis work, as in the past spccics liave 

 l)een vaguely iv^corded as coniing tfoin Egypt without any clear idea 

 of the geograpliical boundaries of tlie country. It is vcry difficult 

 to adopt tiie i)resent polit ical boundaries for thcy are liablc to be 

 changed and, nioreover, thcy include at least four distinct l'aunas. 

 We hâve, therefore, adopted Storey's (1) suggestion ofl restricting 

 the terni Egyptian to species coming from a more circumscribed 

 area including the Nile Valley froni Assouan to the Mediterranean, 

 bounded on the East by the Suez Canal and a linc running South 

 from i\hi)\\\. Suez, and on the West by a line running South from 

 Mersa Matiadi, so as to include the oases of Dakhla and Siwa. 

 Fractically ail the species described in tliis volume occur in the Nile 

 Valley itself, and in those few instances where they occur outside 

 tliis area, spécial attention will be drawn to them, in order to 

 prevent their being loosely classified as "Egyptian."
