310 THE ENTOMOLOGIST. 



by picking up stray ones that came across our path ; the specimens 

 do not differ perceptibly from those I have from Granada. We first 

 saw it on May 17th, on which day I captured two males and one 

 female, and from their condition I should say it had then been 

 out several days. It continued in good order until the end of May 

 and I netted one good male on June 13th. The females absolutely 

 refused to part with a single ova, and a search on the yellow 

 crucifers growing in the cornfields for them was not successful. 



Colias hyale, not very common, first seen on May 26th. 



C. edusa. — Abundant during the whole period of our stay, 

 successive broods continuously appearing. Ab. 'pallida was not 

 uncommon. 



Rhodocera rhamni and R. cleopatra. — Hibernated specimens of 

 both these species were not uncommon amongst Rhamnus in the 

 Guadalavier gorge. 



Thecla spini. — Common on the hilltops around Albarracin, and 

 some larvae I found at Santa Croche, on Rhamnus licyoides, 

 produced this species after my return to England; first seen on 

 June 8th. 



Callophrys rubi. — A few specimens of this species of the var. 

 fervida form occurred generally, my examples are in addition all 

 ab. immaculate/,. 



Chrysophanus alciphron var. gordius. — This species according to 

 Zapater is abundant ; we, however, did not find it so, and, except for 

 a few examples on the hilltops on June 13th, it was not seen. 

 These examples, which are all males, have a much stronger purple 

 flush than Swiss or French specimens, and come near some ab. 

 intermedia from Piedmont, which I have seen. 



G. phloeas. — Not common. 



Lampides baeticus. — Certainly the most abundant Lycasnid we 

 saw at Albarracin, chiefly frequenting sainfoin fields, where it was in 

 great numbers. Some of the examples were of large size — one of 

 mine expands 42 mm. It occurred continuously during the whole of 

 our stay. 



L. telicanus. — Frequenting the same localities as the last, but was 

 not common, usually one or two examples were taken each day ; 

 first seen on May 25th. 



Scolitantides orion. — A rather small race, of which the average 

 expanse is about 28 mm., was not very rare in the Guadalavier gorge 

 near Santa Croche. These examples are mostly var. ornata, one or 

 two are, however, quite black = var. nigra. I also took one specimen 

 at Puerta de la Losilla ; first seen on May 18th. 



S. baton. — Abundant amongst its foodplant Thymus, everywhere 

 on the dry hills at the time of our arrival at Albarracin. The form 

 is entirely var. panoptes, without the slightest indication of the red 

 band underneath, which is found in the type. 



Plebeius arejus = aegon. — A very interesting and beautiful form 

 occurred in small numbers towards the end of our stay, probably it 

 was not even then fully out. Of the named local races it seems to me 

 to come nearest to the var. hypochiona of ftambur. In size the 

 males almost equal var. bejarensis, Chapman, expanding 32 mm. and 

 much resemble that form except that the black border on the upper sides
