Hah. : Algeria : Biskra and Hammain-es-Salahiu, © in galls on 

 Tamarix sp., I-IV, excl. 12.IV— 28.VI.1903 {Whm.). Forty-eight 

 specimens. 



The galls made l)y the larvae on the l)ranches of the Tamarisk are not 

 terminal, and are usually somewhat lateral, or larger on one side than 

 on the other; they are at least half -hollow. I found these galls 

 abundant at Biskra, and at Hammam-es-Salahin from January to 

 April, and bred specimens continuously from April to the end of Jime.
