We first captured a specimen of this species in 1909 on our journey to El 

 Oued ; and in 1912 Dr. Hartert got four specimens on his expedition to In-Salah, 

 and he captured the species again on the Oued N9a in 1914.

 (1912) (Geryville). 



We found a larva at Boghari which unfortunately died, but I was able to 

 preserve it, and it is a fine specimen. It differs from the two larvae sent by Faroult 

 and also from the figure of Mr. Oberthiir by having the hair thicker and much 

 more grey ; but one of Faroult's larvae is intermediate between it and the figure, 

 while the second larva is exactly like the figure.
