from the region of the Straits of Gibraltar. 377 



in tone than British examples, but not otherwise 

 different. 



P. cegeria, L. — As plentiful as the last species, and 

 found everywhere throughout the year. Always of the 

 dark type-form, which I have also taken at Ferrol, on 

 the north coast of Spain. 



Ejmiephile janira, L., var. hispulla, Hiibn. — Abundant 

 everywhere in the open country from May 7th to the end 

 of August. The type-form not met with. 



E. ida, E. — One of the commonest butterflies, fre- 

 quenting open bushy places throughout the region. First 

 observed May 12th, 1887, and I have seen the females 

 in good condition in the middle of September. 



E. pasipJiae, E. — Also very common and generally dis- 

 tributed, and found in the same situations as the last ; it 

 abounds on the slopes of the Eock of Gibraltar (where I 

 have observed it on April 25th) at San Roque, Malaga, 

 Tangier, and Benziis Bay. Unlike E. ida, it lasts but a 

 short time, being quite over by the middle of June. 



Coenonympha arcanioides, Pierret. — Found only in 

 Marocco, where it is common throughout the summer 

 in dry bushy situations. At Tangier I have taken it as 

 early as March 10th ; it also occurs at Esmir and Benziis 

 Bay. 



6'. dorus, E. — Locally common on the downs beyond 

 San Pioque, and on open hill-sides in the cork-woods ; 

 also at Benziis Bay, but apparently rare there. June 

 24th to the end of July. 



C. pamphilus, L. — Quite a rarity ; found on the Rock 

 of Gibraltar in May, 1887, and near Tetuan on June 20th, 

 1888. Both these specimens are richly marked, and the 

 Tetuan example has well-defined dark borders to all 

 the wings above, but they do not exceed English examples 

 in size. 



Spilothyrus alccce, E. — Rare. Taken near Cabrita 

 Point, May 16th, and at San Roque on June 18th, 1887. 



>S'. althacs, Hubn. — Common everywhere almost all the 

 year. Taken on the glacis of the fortifications at 

 Gibraltar on March 14th, 1888, and as late as November 

 20th at San Roque. 



Syrichthus ^woto, E. — Very common and generally 

 distributed. There appear to be two broods, the first 

 appearing in May (10th), the second, which is more 

 numerous, in July, and continuing on the wing until the
