LEPIDOPTERA AT ALBARRACIN IN MAY AND 



JUNE, 1913. 



By W. G. Sheldon, F.E.S. 



(Plate XII.) 



(Continued from p. 289.) 



The number of species of Rhopalocera met with was seventy- 

 three, as follows : — 



Papilio podalirius var. feisthamelii. — Generally distributed but 

 not common ; first seen on May 25th. 



P. machaon. — A few specimens only seen in the neighbourhood 

 of Santa Croche. 



Thais rumina. — Zapater says " this species is very scarce " ; it 

 certainly is not so now, for it was to be seen everywhere on the dry 

 hillsides, especially at and near Santa Croche, where its foodplant 

 Aristolochia pistalochia grew abundantly. The specimens are of full 

 size, but are pale and do not show any tendency towards var. 

 cantaneri. The front wings are well blotched with red. 



Aporia crataegi. — Not uncommon and generally distributed ; first 

 seen on May 31st. 



Pieris brassicae and P. rapae. — Generally common. 



Pontia daplidice — The first brood of this species, var. bellidice, 

 was flying at the commencement of our stay, and a second brood was 

 very abundant in the middle of June. These latter were very fine 

 examples of var. raphani. 



Anthocaris belia. — Was seen flying rapidly over cornfields in 

 May, and an ovum I found on a yellow crucifer produced the summer 

 form var. ausonia, after my return to England. 



Euchloe cardamines. — Common in May. 



E. euphenoides. — Abundant everywhere, it was the first butterfly 

 I saw on arrival at Albarracin, and it continued in good condition 

 until the middle of June ; the males have the orange patch with 

 strongly margined black border to the edge nearest the base of the 

 wings, and in some instances the veins in this patch are covered 

 with black scales also. Some of the females have the apical patch 

 light orange as in Riviera specimens, others are the usual Spanish 

 form, with the orange patch thickly covered with dark scales. 



Zegris eupheme var. meridionalis. — This beautiful species occurred 

 everywhere in cornfields, but was not by any means abundant, or 

 easy to catch, especially the males, which flew very rapidly ; conse- 

 quently our bag was a small one. By working for it one could get 

 three or four specimens in a day, but we usually contented ourselves
