A FEW weeks' ENTOMOLOftlSING IN SPAIN. 89 



wing. The Canon told us this was the first walk he had taken for 

 some two years, and we felt honoured accordingly. He has many 

 interesting recollections of his entomological researches here and else- 

 where, but he does not now do any serious collecting. He has a very 

 extensive library, including some rare entomological books ; it shows 

 that, until his retirement to Albarracin, where he has resided for 

 twelve or fifteen years, he must have had very active interest 

 not only in many literary and theological subjects, but in many 

 branches of science. We saw him several times afterwards, and his 

 kindness and courtesy made a strong impression upon us. At 

 Albarracin we collected chiefly in two localities or districts. These 

 were probably the most profitable and interesting, but there were 

 others time did not permit of our examining, and doubtless others 

 of which we were in absolute ignorance. One of these was down the 

 stream of the Guadalaviar some four miles, where a large affluent, 

 absolutely dry during our stay, joins it from the left bank. The basin 

 of this little stream seemed to possess more abundantly the species that 

 attected a large area of similar country round about. It is a dry, 

 stony, undiilating region, in which the limestone rocks are very close 

 to the surface. It grows savin trees of considerable size, up to perhaps 

 2oft. high. The Kiihedra nehrndemis, a shrub rarely reaching 4ft. 

 high, belonging to the Gnetacnae or joint-firs, but excessively woody, 

 was also commonest here. Many spiny shrubs of much smaller 

 size, papilionaceous chiefly, were also common. Here the splendid 

 Ihfpn'Htia saiti/ttinta (see Champion, Tranti. Ent. Soc. London, 1901, p. 

 879), was frequent on the KpJiedra, and on the same plant, we took 

 larvct, apparently those of Albarraciiia korhi as well as larvte of a 

 Ccrostoina not yet determined. Here also were apparently the head- 

 quarters of ■Satyrns pricKri, whilst S. semele, S. fidia, S. alci/one, 

 S. actaca, S. brueis, S. circe and S. statiliniis were (except S. actaea) 

 more or less common, Poh/onDnatns corydon var. Iiispana, was common 

 here, as well as An/i/jmis cldontdippe. In the valley of the Guadalaviar 

 itself, all these and other butterflies occurred, S. fidia and 6'. circe 

 being especially common, but iS. prieuri was rare. In going down to 

 this point along the Guadalaviar river we noticed the opposite bank to 

 be clothed to a considerable height with a thick wood, chiefly of small 

 oak trees. We much regretted that no opportunity of ramliling in 

 this occurred, since it was of a character so distinct from that of any 

 other ground we collected in. 



Our other excursions from x\lbarracin, were up a valley opening to 

 the south, with a small trickle of water fed by springs, and leading 

 onwards to Puerto de la Losillo, which we thrice visited. In this 

 direction, one leaves, after a mile or two, the limestone, and gets 

 amongst hills of a dark red sandstone, one also reaches a region in 

 which pine forest still comes to within a few miles of Albarracin. 

 The iiumediate neighbourhood of Albarracin, like Cuenca, is bare of 

 trees, one supposes by human agency. Many species of butterflies are 

 frequent in this region, Sati/nis /irietiri in the lower portions, and, on 

 the higher ground near the Puerto de la Losillo, Krehia zapateri occu)'s. 

 At one spot at least on the way up we found both species together ; 

 no doubt here the sandstone and limestone run side by side. 



On the ord of August we went by cart to Noguera, where we 

 lunched. The journey occupied nearly four hours, very nnich the
