from the region of the Straits of Gibraltar. 381 



are much larger and finer than EngHsh examples ; they 

 expand 2 in. 9 lin. (=:69'6 mm.). 



A. casta, E. — I found only one example of this beautiful 

 little tiger-moth, at rest on the ground near San Roque, 

 on April 12th, 1888. 



Phragmatohia fiiliginosa, L. — Only observed in Ma- 

 rocco, at Esmir, and in the marshes near Tetuan, where 

 the cocoons are to be found not uncommonly in the 

 winter, spun up on the rushes. The specimens bred 

 from these are remarkably large and brightly coloured, 

 on an average measuring 1 in. 6|- lin. (= 39 mm.) in 

 expanse. 



Orgi/ia Josephime, Oberth. ('Etudes d'Entomologie, 

 Lep. d'Algerie,' vol. 6, div. iii., p. 77, and plate ii., fig. 5, 

 (?). — This very beautiful and interesting species was 

 described by M. Oberthiir from specimens obtained at 

 Lake Sebgha, in Algeria, by M. Austaut, in April, 1880. 

 I found it at Esmir under the same circumstances as the 

 preceding species, but only bred two males from a good 

 many cocoons collected ; the wingless females, which 

 are covered with ashy-grey woolly hairs, appear to be 

 much more numerous. 



0. trigotephras, Bdv. — Common on the Rock of Gib- 

 raltar, at Tangier, and Benzus Bay, in June. In its 

 habits it exactly resembles 0. antiqua, flying actively 

 by day. 



Ocneria dispar, L. — Not common on the Rock of 

 Gibraltar, and in the cork-woods of Almoraima, but 

 observed in all its stages in most astonishing profusion 

 at Monte de la Torre, about four miles from Algec^iras, 

 on June 28th, 1888 {vide Entom. Monthly Mag., vol. xxv., 

 p. 65). 



0. atlantica, Ramb. — One female of this interesting 

 species was found at rest on a stone wall at Gibraltar, 

 July 5th, 1887. 



Porthesia aurifliia, L. — Not uncommon at Gibraltar 

 and San Roque in June. The black dots on the pri- 

 maries, occasionally developed in English examples, are 

 very conspicuous in these specimens. 



Cossus ligniperda, L. — Not common. The larva 

 observed in elm and poplar trees at Campamento. 



Zcuzera asculi, L. — Found once on the Rock of 

 Gibraltar, June 11th, 1887. A large and well-marked 

 female specimen.
