Victor Faroiilt sent 1 S and 1 ? bred specimens, evidently starved, dated 

 September 23, and 1 caught specimen, September 10, J913. 



317. Cymbalophora powelli Oberth. 



Cyiiihalophora pnwcUi Oberthiir, BitU. Soc. Eiilum. France p. 333 (1910) (Geryville). 



Dr. Nissen and Victor Faronlt both found this species abnndant in September 

 and October 1912 and 1913. Faroult sent in a large series of both Si and ¥ ?. 



318. Cymbalophora haroldi Oberth. 



Cymhiihipliora haroldi Oberthiir, Etml. Lep. Comji. Fasc. v. pt. 2 p. 123 (1911) (Aflou). 



In Gnelt-es-Stel this species appears to be extremely rare, while at Aflou 

 Harold Powell found it to be a fearful pest. 



Victor Faroult sent 1 perfect S dated September 22, 11)13, which agrees 

 absolutely with the figure 1U46 in J'Jtiid. Lejj. Comp. Fasc. vi. pi. cxi,x. (1912). 



319. Utetheisa pulchella (Linn.). 



Tinea 2ndchella Linnaeus, Sysl. Nat. ed. x. vol. i. p. 534. No. 238 (1758). 



5G specimens were collected by Victor Faroult dnring the months of April 

 May, June, and July 1913. 



ZYGAEITIDAE. 



Zygaeuiuae. 



320. Zygaena loyselis Oberth. 



Zygaena loyselis Obertlii'ir, Elud. Entoiit. i. p. 34. pi. 4. fig. 4. (1876) (Daya ; Lambessa). 



This species appears to be rare at Gnelt-es-Stel, as Faroult only sent in 

 18 specimens collected end of May 1913. They are nearly all in poor condition. 



321. Zygaena thevestis Stdgr. 



Zygaena thevestis Staudinger, Berl. Ent. Zeitsch. vol. .\x.xi. p. 33 (1887) (Tebessa). 



Dr. Seitz in the Grossschmetterlintfe der Erde, vol. ii.,has united as aberrations 

 under Zygaena J'atonia the following forms : titrina Stdgr., staudingen Aust., 

 logseUs Oberth., confluens Dziurz., valentini Bruand., and tJtevent/x Stdgr. Since 

 this was published in 19U9, however, Monsieur A. Nelva of Batna has succeeded in 

 breeding all these forms, with the exception of thevestis, and he has proved that 

 loyselis, vitrina, and favonia are three distinct sisecies with different larvae and 

 habits. 



Z.fatonia has a pale green larva with pink head and very few if any black 

 spots ; it feeds on Eryngium campestre, and skeletonises the upper mature leaves. 



Z. loyselis has a darker green larva with black head and a number of dark 

 spots, and feeds also on Eryngium campesfri', but ^bores into and feeds in the 

 central stem of the plant where it enters the ground ; the cocoon of loyselis is boat- 

 shaped and comparatively smooth, while tliat cX favonia has three or four strongly 

 protruding longitudinal ribs.
