428 Mrs. M. De la B. Nicholl on the 
from east to west, and six or seven from north to south, 
a beautiful wild country, well watered, well wooded, and 
well pastured. Albarracin itself is built on a precipitous 
lias rock, overhanging the Guadalaviar, which flows 
for many miles through las gorges—which we found 
very good ground for insects. 
Arriving at Cuenca with Mr. EK. Witty, of Barcelona, 
on the 14th of June, we presented our introductions to 
Sefior Don Ventura Prosper, Professor at the Cuenca 
University, and were most kindly received by him. He 
gave us much useful information, and also an introduc- 
tion to Canon Zapater, of Albarracin, which afterwards 
proved most valuable to us, as the Canon is a well known 
entomologist, and the original discoverer of Hrebia zapatert 
and Satyrus prieurt and uhagoni. We stayed at 
Cuenca for a week, but were unfortunately too late for 
Zegris eupheme, which must have been just over. It is 
common at Cuenca in May, and is taken more or less 
abundantly throughout the Albarracin country. We then 
made an excursion of two days to Lago d’Una, a charm- 
ing little Jake about eighteen miles up the Jucar valley, 
and a good place for butterflies. We got Thecla roboris 
there, A. hecate, A. ino, and many other insects. Return- 
ing to Cuenca, we started thence on mules for Albarracin, 
first following the Jucar right to its source, then crossing 
the Upper ‘agus valley, and striking the source of the 
Guadalaviar, we descended that river to Ajbarracin, 
where we arrived on June 30th, after four days of most 
enjoyable travelling. We took, on our way, P. apollo, 
just out; Mrebia evias, in very bad order; Lycena 
aiion, scarce and in bad order; Melanargia ‘ines, 
M. iapygia, and M. lachesis, just out, and Cenonympha 
iphioides, flying’ over a wet field in the Tagus valley, in 
some numbers. ‘This was described by Dr. Staudinger 
as a variety of CO. iphis, W.V. (= amyntas, Poda, which 
is the older name) ; it differs, however, from CO. amyntas 
in having the ocelli on the underside of the hindwing 
evenly disposed, whilst in that species the ocellus above 
vein 3 is displaced inwards; also there are no white 
blotches on the inner side of the series of ocelli; these 
differences seem perfectly constant, and there can be little 
doubt that it is a distinct species. It is also closely 
allied to C. leander, Esp., from Russia and Hungary, but 
differs from it in having an orange terminal line on the 
underside of the forewing, and in having a silvery line on
