B. Separate Works. - 
FiGUiEii, L. Les Insectes. 8vo, pp. 616. Paris, 1867. 
This appears to he a well-executed popular treatise on insects; 
and is illustrated by an immense number of woodcuts, generally 
of very good quality. An English translation of it has lately 
appeared, under the title of " The Insect World.^^ 
Girard, Maurice. Les Metamorphoses des Insectes. Paris, 
1867. 
This little work, which the Eecorder has not seen, contains an 
account of the transformations of insects and a description of 
many other points in general entomology. It has been exceed- 
ingly popular in France. 
Goureau, C. Les Insectes nuisibles h PHomme, aux animaux 
• et h Peconomie domestiques. Paris, 1866, pp. 258. 
In this little volume, which appears to be a publication of the 
Society des Sciences de PYonne, Goureau gives a semipopular 
account of the various insects which are to be regarded as inju- 
rious to man himself, to domestic animals, and to manufactured 
articles, whether of animal or vegetable origin. The author 
justly remarks that these insects have received less attention 
than those which affect our cultivated plants ; but this is per- 
fectly natural, because, as a general rule, however troublesome 
they may be, the injury which they do us is of far less impor- 
tance. 
Martens, E. von. Die preussische Expedition nach Ost-Asien. 
Zoologische Abtheilung, Band i. Berlin, 1865, pp. 192. 
This portion of the zoology of the Prussian scientific expedi- 
tion to Eastern Asia contains general remarks on the zoology of 
the countries visited, and is of considerable interest as regards . 
the geographical distribution of animals. The insects occupy a 
comparatively small portion of its contents. 
Moller, L. Die Abh'angigkeit der Insecten von ihrer Umgeb- 
ung. Leipzig, 1867, pp. vi & 107. 
In this little work (an inaugural dissertation read before the 
philosophical Faculty of the University of Leipzig) the author 
brings together a series of valuable observations on the depen- 
dence of insects upon surrounding conditions. He indicates the 
influence of climate upon the distribution of insects, the effects 
of the nature of the soil upon their well-being (both directly as 
furnishing more or less favourable places of residence, or breed- 
ing-localities, and indirectly as favouring or limiting the growth 
of certain plants in particular places), the relations between in- 
sects and plants, and between them and other animals or animal 
products, and, finally, the effects of human traffic or industry 
in modifying the results of natural conditions. In a concluding 
section Moller briefly sketches the part played by insects in the 
1867. [voL. IV.] p
