LEPIDOPTERA AT ALBARRACIN. 329 



common at the bottom of hot dry gorges, in company with Melitaea 

 desfontainii and other species. 



The specimens perplexed us a good deal, for they varied in 

 expanse from 23 mm. -31 mm. and also in tint on the upper sides and in 

 spotting on the under sides ; and bearing in mind that Zapater gives 

 the nearly allied C. lorquinii as occurring, one could not be certain 

 that some of the specimens were not that species. Mr. Eayward's 

 careful examination of the genitalia, however, proves them to be all 

 C. sebrus. Nearly all possess the second spot from costa on hind 

 wing underneath, the absence of which is given by Kane as a 

 distinguishing characteristic for G. sebrus. 



Gyaniris semiargus. — Only a few specimens seen, the first on 

 June 7th. Zapater speaks of this species as not being common in the 

 district. 



Nomiades cyllarus. — A very fine form was abundant in the 

 sainfoin fields in May. Expanding up to 37 mm. both sexes have 

 numerous bold ocelli underneath, and the blue at the base of the 

 wings, upper side, in the females is much brighter than is the case 

 in French specimens. 



Polygonia c-album. — One or two specimens were seen by Mr. 

 Jones after I left. Zapater speaks of it as rather scarce. 



Eugonia polychloros. — Larvae were frequent on elm, and the 

 imagos were just coming out on June 20th. 



Aglais urticae. — Larvae were common in May, and the imagos 

 bred therefrom proved to be a very magnificent race, with an average 

 wing expanse of 60 mm., and no doubt this expanse would be 

 considerably increased in the largest captured examples. The chief 

 characteristic of the race, apart from size, is the- richness of the 

 tawny ground colour, which in this respect equals that of the 

 Corsican form var. ichnusa, the width of the band on the hind wings 

 in many examples, and the almost total suppression of the pale 

 patches in the tawny bands, especially the one nearest the anal 

 angle of the superiors. On my previous visit to the district I had 

 noticed the rich coloured examples of this species, but they were not 

 common and were strong on the wing, and I was then not able to 

 secure a specimen for comparison. This form appears to be a well 

 marked geographical race, which approaches in size and character- 

 istics the Chinese form var. chinensis. I propose the name of var. 

 teruelensis, n. var., for it. (See Plate xii., figs. 1, 2.) 

 Pyrantels sardui. — Abundant. 



P. atalanta. — Not common, a few larvae and imagos. 

 Melitaea desfontainii. — This fine Spanish species was first seen on 

 May 24th in the Guadalavier gorge near Santa Croche. Until 

 June 7th we found it very scarce, only capturing one or two examples 

 each day. On this date, however, Mr. Jones, on other species 

 intent, prospected a cross gorge which came down to the main one, 

 and discovered that this species was common in it, and from there 

 we got as many specimens as we required. Afterwards we found it 

 in similar places elsewhere, such as " The Vega," and on June 18th 

 it was abundant at Losilla. 



The males frequent the bottom of hot stony gorges, settling upon 

 the rocks, taking short flights, and when not startled returning to
