Zygaena loyselis ocHdetUalis Oberthiir, Etud. Lepidop. Conip. Faac. XII. p. 208 (1916) (G&yville). 



We never found this insect in the west of Algeria, as we were too early at 

 Oran, Lalla Marnia, and Tlemcen, and at Saida we only caught 2 Zygaenas 

 altogether.

21. Zygaena favonia favonia Frr. 



Zygaena javonia Freyer, Neu. Beitr. Schmett. vol. v. p. 76. t. 428. f. 1 (1845) (Turkey ! !). 



Freyer described favonia from a specimen captured by Dr. Wagner, but 

 evidently not reahsing that Dr. Wagner had also made extensive journeys in 

 Algeria, he gave a wrong locahty. Z. valentini Brd. appears to be the typical 

 foim and javonia only an occasional very dark aberration, but favonia, having 

 been pubhshed two j^ears before, must stand. 



We collected favonia first at Hammam R'ihra in 1908, where most of the 

 specimens had only one pink ring, and we have taken it at ELhenchela, Saida, 

 and Hammam Meskoutine among other places. Through the help of Mr. A. 

 Nelva, I found a few larvae of this species myself at Batna and later at Hammam 

 Meskoutine. The Tring series numbers 587 examples.
