4__P. machaon, L. Common throughoi^t the ro<?ion from February to 

 Oetolu>i-. Specimens bred from lai'vtv fonnd on fennel at Gibraltar 

 and Konda. 



II,— Thais rumina, L. The first example of this beautiful species I observed 

 and captured on February 11th (11)10). It is not so abundant on the 

 Rock as formerly, but is widely distributed throughout the district, 

 and I have taken it in good condition as late as May 21st (1910). 



4i,.—Pieris hrassica', L. Common tliroughout the region during the whole 

 year. 



48.— P. rapw, L. Also common all the year throughout the region. 



57. — P. daplidice, L. This I have found to be more plentiful throughout the 

 region than the two preceding. There appears to be three distinct 

 broods during the year. The spring brood (var. hellidice, O.) occurs in 

 the Cork Woods about the third week in February. The summer 

 brood appears about the middle of April and remains good until the 

 end of July : these are slightly larger, and have less green on the 

 underside of hind wing than var. hellidice. The aiitiunn brood appears 

 during the first week in August and lasts until November : these are 

 generally a good deal smaller, and the vinderside of the wings have 

 miich less, paler, and more yellowish-green than the summer brood. 

 (Probably var. raphani, Esp.). 



60. — Euchloe helemia, Esp. Common throughout the region, and one of the 

 earliest butterflies on the wing. I have observed it in the Alameda 

 Grardens early in Janizary, but my first capture in the season was 

 February 22nd (1912). The ab. glauce, Hb., appears about the third 

 week in April, and I have taken it in good condition at Tarifa, as late 

 as June 12th (1911). 



62. — E. belia, Cr. I took a fine specimen of this species at Tangier on 

 March 24th, 1912, but it is apparently very rare in this region, except 

 at Granada, where it occurred commonly in May, 1911. The var. 

 ausonia, Hb., was common at Granada in the middle of June, 1911. 



63. — E. tagis, Hb. I found this insect common on the Rock of Gibraltar, on 

 March 3rd, 1912, at a spot where I had previously taken two specimens 

 on April 16th, 1910, and several others between April 2nd and 30th, 

 1911. The locality is about 500 feet above sea-level, near the Jews' 

 Cemetery, at the south end of the Rock. The species appears to be 

 well established in this restricted locality . I have searched for, but 

 have not met with it, in any otlior part of the region, but Mr. G. O. 

 Sloper took 15 good specimens in the Cork Woods on April 8th, 1911. 



69. — E. carda^nines, L. I took two males of this species in the Cork Woods on 

 April 7th, 1912, and one male on April 21st, 1912. This insect appears 

 to be scarce in the district. 



72. — E. eupheno, L. This species occiu's only on the African side. On 

 March 22nd, 1912, I met with it near Tangier, and on this and the two
