a native originally of the East Indies, is found in the Archipelago 
of the Canaries, as well as at Madeira and Porto Santo. It 
abounds on the volcanic slopes of the Brena, in the island of Pahna ; 
at Teneriffe, some aged specimens are found in the valley of Ora- 
tava, and in the Ravin de 1'Enfer ; adorning the basaltic pinnacles 
of the eastern slopes. 
Pistachus lentiscus, and Olea Europea are profusely distributed 
over the great Canary, but in Teneriffe and Palma, they have given 
way to the culture of the vine, though the names, still existing in 
the hills and valleys, shew that they were once abundant. 
There are many other remarks and observations which might be 
taken from this department, but in noticing them all, we should 
have in reality to transcribe the chapter. We unhesitatingly recom- 
mend the work for perusal to botanists ; they will find much informa- 
tion and much useful criticism upon the histories of Huinboldt and 
Von Buch, &c., which have the additional merit of being candidly 
and modestly expressed, do full justice to the labours of these dis- 
tinguished individuals, and we feel convinced will be read by them 
with pleasure, and without any of that feeling of asperity which 
the remarks of one traveller upon the works of his predecessors so 
frequently calls forth.

Hymenopterorum Ichneumonibus affinium monographic?, Genera 
Europcea et Species lUustranles. Scripsit C. G. NEES AB ESEN- 
BECK. 2 vols. 8vo. 
This work, though one of importance, is known to be merely an 
extract from a much more voluminous one, still in MS., consisting 
of ten volumes in quarto. It is preserved in the museum of Bonn, 
to which the author was formerly attached, prior to his settlement 
at Breslaw. He had there formed a collection of 25,000 insects, 
among which are contained all the Hymenoptera described in the 
work above named. M. Nees d'Esenbeck is a noted botanist, and 
successfully combines the study of two departments of natural his- 
tory, the practical pursuit of each of which so well accords with the 
other. This work may be regarded as a supplement to or rather a 
completion of M. Gravenhorst's Ickneutnonologia Europcea., publish- 
ed in three very thick volumes in 1829. These authors worked 
with a mutual understanding of each others labours, and while the 
latter undertook and completed the Ichneumones, properly so called,
