A COLLECTING TRIP TO THE CAMARGUE, ETC. 113 



overgrown spots near the river a few miles below Albarracin 

 they existed in great numbers. They were given to occasional 

 long soaring flights, beautiful manifestations of activity and life. 

 When on the wing they were by no means easy of capture, but 

 my observant friend, who always seemed to achieve maximum 

 results with a minimum of exertion, found out another way. 

 Settling quietly after a flight, they rest on stems for a brief 

 space with fully outstretched wings. They are then conspicuous 

 and easy to take until the wings are gradually closed over the 

 back, when they become more difficult to see. One large example 

 of A. longicornis was captured in the grip of an Asilid fly. 



The following other Neuroptera were token:— ChrijsojM pra- 

 sina, lineolata, and vulgaris; Hemerohius humidi, H. stigma; one 

 example of Dilai' (taken by Dr. Kis), probably meridionalis ; 

 Macronemurus appendiculatm and Creagris plumbeus. 



Plecoptera were represented by Perla marginata and Chloro- 

 perla grammatica at the Guadalaviar, while a good series of 

 Nemoura falviceps was found at a small stream on the way to 

 Puerto de la Losillo. 



Probably the Guadalaviar produces more species of Tricho- 

 ptera earlier in the season. Hydropsyche lepida and Metalype 

 fragilis were common, and flew to the lights in the Posada. 

 Other species were Hydropsyche instabilis and guttata, and Seri- 

 costoma vittatum, the last-named being common at the small 

 stream above mentioned. The only example of Hydroptilidse 

 taken was unfortunately lost. 



Going over ground that has been so well worked by experi- 

 enced lepidopterists, little that is novel can be expected in the 

 record of our doings amongst the butterflies. No doubt we 

 overlooked much and made some mistakes. Amongst many 

 specimens of Melanargia lachesis, I find but one pair of M. 

 japygia. Of course, the latter may not have been fully out. On 

 the other hand, M. ines was found here and there, mostly in 

 rather chipped condition, it is true, but the species appears to 

 have been missed altogether by most of our predecessors. A 

 single specimen of Coenonympha iphioides occurred in a meadow- 

 like opening in the woods near the Puerto de la Losillo. We 

 appear to have expended a tremendous amount of energy on 

 Satyr us briseis, the result being a long and fine series, while of 

 the much-desired S. prieuri my total catch amounts to only 

 three males, and my colleague reports that his is about the same. 

 On the whole, however, we seem to have met with most of the 

 species that were to be looked for at the time of our visit. 



On our way back from Albarracin we spent part of a day at 

 Narbonne. Neither of us was particularly fit, and it began to 

 dawn upon us that there might be something in the remarks 

 that we had been hearing about the heat ! We had practically 

 no collecting, but it was interesting to see Sympetrum fons-
