334 NOVITATES ZOOLOOICAE XXIV. 1917. 



are not at all like this, while I have 2 favonia from Batna which have the ground- 

 colour exactly lilce aurata Blachier. My 5 from Mogaclor are not like auraUi, 

 but very dark, similar in colour to sarpedon ab. vernetensis Oberth. ; aurata 

 Blach. and a form almost like typical favonia were got by Mr. Meade- Waldo 

 about 12,000 feet on Tizi Gourza in July 1901, where they were very abundant. 

 It would therefore appear that two races of favonia occur in Morocco : first, 

 the high mountain form, which, however unfortunately, must stand as Z. 

 favonia aurata Blach. ; second, the Atlantic Coast form, which requires a new 

 name.] 



18. Zygaena zuleima Pierret. 



Zygaena zuleima Pierret, Ann. Soc. Entom. France, vol. vi. p. 22. tab. 1. f. 8 (1837) (B6ne). 



We found this insect very scarce and local, and it was only on our sixth 

 visit to Algeria in 1914that we dropped across it accidentally in the Arab cemetery 

 at Souk Ahras, where it positively swarmed.

Zygaena loijaelis Oberthiir, Etud. Entom. liv. i. p. 34. t. 4. f. 4 (1876) (Lambesaa). 



Although we collected Zygaenas in considerable numbers in several districts 

 where loyselis occurs, we never caught a specimen ; though after Mr. A. Nelva 

 showed me how to look for them, I found several larvae at Batna.
