37. Zygaena carniolica lahayei Oberth. 



Zygaena orana lahayei Oberthiir, ? ! ? ? J 



I have been quite unable to make out where Jlr. Oberthiir first published the 

 name lahayei. It would be of the utmost use to entomologists and save an infinity 

 of trouble if when writing about species or varieties, whether of their owti creation 

 or those of others, all entomologists made it a rule, as we now do at the Tring 

 Museum, to quote the original description as well as the name. 



It was supposed by Mr. Oberthiir that c. lahayei was confined to the Gery- 

 ville district, but Faroult sent it to me from the neighbourhood of Djelfa.

The Tring series is small, only 42 specimens. There are 3 specimens in the 

 British Museum, Geryville, Leech coll. 



38. Zygaena camiolica maroccana subsp. nov. 



?. I should under ordinary circumstances strongly deprecate describing 

 subspecies from a single specimen, especially as Zygaenas are so variable ; but 

 in this instance the differences are too palpable for error. 



The specimen came in a small collection from Mogador, the whole of which 

 was sold to me by Messrs. Staudinger and Bang-Haas. 



This specimen differs at first from all Mauretanian forms of carniolica by 

 its large size. It equals in size the S? of the fine Syrian race described and 

 figured by Mr. Oberthiir as carniolica praestans (Etud. Lipid. Covip. Fasc. IV. 

 p. 637 (1910) (Akbes) ; Etud. Entom. liv. xx. pi. 7. ff. 115, 116 (1896)). 



It differs from c. praestans in having less white round the first five red spots of 

 the forewing, but the most striking difference is the very enlarged almost quadrate 

 sixth spot, which is entirely without any white ring.

39. Zygaena theryi Joann. 



Zygaena theryi de Joannis, Bull. Soc. ErUom. France. 1908. p. 203 (Environs de Philippeville). 



My description of this fine Zygaena appeared just a few weeks later than that 

 of the Abbe de Joannis, so that my name of nisseni has to give way to that of 

 theryi. I described it as a subspecies of lavandulae, but Mr. Oberthiir considers 

 it to be a distinct species, forming the transition from Zygaena to Arichalca 

 Wallengren. 



It will require a careful morphological c9mparison to prove the truth or
