ever have been separated therefrom as a distinct order. It seems to 
us, however, that the authors have to a certain extent been in error 
in placing the Dulichiide among the aberrant Amphipoda, their 
true alliance being evidently to the typical section, with which they 
are described as agreeing in every respect, except in having the last 
two segments of the ‘‘ pereion’’ fused into one, and the last segment 
of the ‘pleon’’ absent. In all other characters, such as especially the 
full development of the tail, the absence of rudimentary feet, and the 
separation of the coxee from the segments on which they stand, the 
Dulichiide agree with the higher Amphipoda, and differ in the same 
proportion from the aberrant forms, whether we take the spectral 
Caprelle or the louse-like Cyami as typical of the second group. 
This, however, is an objection easily got over; and we can only ex- 
press a hope that the renewed publication of the book may now pro- 
ceed regularly, and that it will find as many purchasers as its careful 
elaboration and the beauty of its printing and illustration certamly 
entitle its publisher to expect. 
dA Catalogue of Phytophaga (Coleoptera, Pseudotetramera). By 
the Rev. Hamuer Ciarx. Part I. With an Appendix, con- 
taining Descriptions of new Species, by H. W. Bares and the 
Rev. Hamuer Cuark. 8vo. London: Williams and Norgate, 
1866. 
During the eighteen years that have elapsed since the completion 
of Lacordaire’s classical Monograph of the Phytophaga, entomolo- 
gists have been most industrious in describing new genera and spe- 
cies of this most attractive group of beetles. The result of this 
industry is the accumulation of a vast mass of more or less scattered 
descriptions of newly discovered forms, which renders it exceedingly 
difficult for an entomologist not making a special study of the group 
to arrive at anything like a clear notion of the number of species and 
genera already known. The Rev. Hamlet Clark (the author of the 
Catalogue now before us) and Mr. J. 8. Baly may be noted as among 
the most active cultivators of this particular department of entomo- 
logy, the latter especially exhibiting a power of production which 
has already rendered his publications very voluminous. It is a ques- 
tion, indeed, how far he may be regarded as doing good service to 
science by the publication of such an infinity of detached notices ; 
but it is quite clear that, until he begins to devote his energies to 
some other group of insects, that monographiec revision of the Phyto- 
phaga which has already become almost an absolute necessity, and 
which will undoubtedly bring about the suppression of a host of 
modern so-called genera, had better be postponed. 
In the meanwhile entomologists will be thankful to the Rev. Hamlet 
Clark for the catalogue with which he proposes to furnish them, and 
of which the first part, including the four Crioceride groups, Sagridee, 
Donacide, Crioceridz, and Megalopidze, is now before us. In this 
catalogue we find the generic and specific synonymy of the insects 
belonging to these groups concisely but clearly set forth, with full
