This species was obtained by Heuglin on the Abyssinian 

 coast, along the Mareb river on the borders of Kassala, and 

 in Kordofan. After that it was lost sight of in Africa until 

 met with by Zedlitz near Keren in Eritrea (J. f . O. l&l i 

 p. 37). It is in all probability a^ migrant from western 

 Asia, where it ranges to Persia.
