catch sight of swishing bushes and some gray-bi'own fur as some 

 animal dived into a cavern in the cliff face. It may have been a wolf, 

 as the man said, but I could not swear to it. 



Of snakes, I am thankful to say, I saw none. The only reptilian 

 met with which interested me was the fine big green lizard (Lacerta 

 ririilis), which we came across everywhere. 



Trout are common in the river, but they are mostly small, and a 

 small crayfish is also abundant. When alarmed, the latter darts 

 rapidly backwards, and is lost to sight in the cloud of mud disturbed 

 by its motion. 



Mr. Sheldon has described some of the most interesting plants of 

 the neighbourhood, one of which is certainly the glorious blue Lininu 

 which is to be met with everywhere on the limestone rocks. The 

 Savin Tree, which is frequent on the same formation, interested me 

 very much. The adult tree strongly suggests a cypress, and it is only 

 when ones comes across a sapling that the characteristic juniper 

 foliage is noticed. A magnificent wild rose with huge, rich yellow 

 blossoms was discovered in one locality near the town. The big 

 asphodels were very common on the hillside, but I do not think they 

 are of the same species as that which I find so abundant in Southern 

 Italy. The root of the latter is a huge bulb like an onion, whereas the 

 Albarracin asphodel has a root consisting of a mass of tubers something 

 like that of our garden plant lucan-illm delaroj/i. Oleanders do not 

 occur so high up in the sierra as Albarracin ; but we saw masses of 

 them in full bloom in dry river-beds between Valencia and Barcelona. 



It only remains for me to place on record our indebtedness to Seuor 

 Don Mariano Rabinad,the Secretary to the Ayuntamiento of Albarracin, 

 to whose kindness much of the success of our expedition was due. It 

 was a matter of great regret to us that during the greater part of our 

 stay Sefior Rabinad was obliged, by official duties, to remain at 

 ]\Iadrid. 



Dysstroma concinnata, Steph. [Witli tln-ec platefi.) 



By E. A. COCKAYNE, M.A., M.D., F.E.S. 



In a paper read before the City of London Entomological Society, 

 Mr. Prout gave his reasons for believing Diisstrania concinnata to be a 

 species distinct frqm 7>. tnincata and /). citrata [iwnianata). These 

 were based on the external appearances and genitalia of the imago, and 

 on differences in habits, time of appearance and distribution. All 

 these species inhabit the Island of Arran, a fact which proves that 

 these differences are not dependent on local climate or isolation. I 

 will summarise the points which Mr, Prout brings out so clearly. 



Dj/sstniina tnincata on Arran is double-brooded, appearing in May 

 and June and again in August and September; D. concinnata is single- 

 brooded, appearing in July or August or even occasionally at the end 

 of June ; />. tnnicata inhabits the low ground, and the larva is a 

 general feeder; l>. concinnata is confined to the high ground and the 

 larva feeds on heather, Valhina ruhiaris. It must be admitted that 

 larvae of both the other species are sometimes seen feeding- on heather, 

 but in my experience they prefer other plants, even on the open moors. 

 TK citrata passes the winter as an egg, D. tnincata as a larva ; the 

 hibernating stage of P, concinnata is unknown. P. concinnata rests on
