wilder surroundings of Alger; but if one goes farther west 
into Oran, new elements are found in the fauna, forms which 
either have come from Spain via Morocco and have not reached 
the Central and Eastern parts of the Tell, or have extended 
their range from the interior northward. To Entomologists 
who wish to collect in the Tell, Hammam Meskoutine in the 
East, Hammam Rirha in the Centre and Sidi-bel-Abbés in 
the West can be recommended. Though the individual 
aspect of these places is very different, they have much in 
common: deep gullies with almost impenetrable brushwood, 
the arable land tilled or turned into vineyards, the rocky 
hillsides a paradise of plants and animals, and the mountains 
covered with woods. Higher altitudes in the Tell are most 
easily reached from Les Glaciéres de Blida, which consists of 
a small hotel at about 4000 ft., quite first-rate for a collector 
who can dispense with the paraphernalia of large establish- 
ments. The hotel stands on a small plateau on the steep 
hillside, surrounded by oak woods where millions of larvae 
of Catocala may be seen in May and June and where many 
good species of moths will come to the lamp, such as 
Apantesis oberthuri, Pergesa porcellus colossus and Notolophus 
splendidus. Above Les Glaciéres is a fine cedar forest with a 
profusion of Viola munbyana, on which feeds the larva of the 
beautiful Argynnis pandora, at times quite abundant here, 
and above the forests there is a large expanse of grassland 
to the top of the mountain, which reaches a height of nearly 
5400 ft. It is a fine collecting ground if the weather is favour- 
able. But being directly above the plain of the Metidja and 
facing the sea, the place is very often in the clouds even when 
there is brilliant sunshine below. 
Though the tourist may not be aware of it—and if he is, 
he need not trouble much about it—the fastnesses of the 
northern Atlas are the haunts of some large mammals. The 
leopard, striped hyaena, caracal lynx and jackal are still to 
be found, but they have become very shy. The lion used to 
be quite common in the Tell and in Eastern Algeria as far 
south as the Aurés Mountains, and it seems quite strange that 
one now can walk about with a butterfly net as the only 
weapon in places which less than forty years ago were still
