M. Leon Fairmaire has published during the past year seven 
parts of his continuation of Jacquelin du VaFs ^ Genera of Euro- 
pean Coleoptera/ a work which is too well known to need piore 
than a passing notice in this place. 
Mocquerys, E. Recueil de Coleopteres anormaux. No. 7. 8vo. 
Rouen, 1804. (Published by the author.) 
The seventh part of this publication, by M. Moequerys of 
Rouen, on monstrosities occurring in various species of Coleo- 
ptera, contains a title-page of the first volume and a classified 
index of the specimens figured in his six previous livraisons. 
He arranges these abnormal individuals in 4 classes, namely, 
1. Mpnstrosities by including examples of over-developed 
antennse, palpi, and mandibles, elytra, legs, tarsi, and claws, and 
gibbosities ; 2. Monstrosities by deficit in the number of parts ; 
3. Monstrosities without appreciable cause, including some very 
singular malformations of the antennae and limbs ; and, 4, In- 
complete development. The examples of monstrosity are repre- 
sented by outline woodcuts on separate pages, each accompanied 
by a short description. Many of them are exceedingly cin ious, 
especially the malformations by excess of the antennae and 
limbs. 
Mulsant, E. and Rev, Cl. Histoire Naturelle des Coleo- 
pteres de France. Terediles. Paris, 18G4, pp. 391, with 
10 plates. 
The volume of MulsanPs great work on the French Coleo- 
ptera published in 1864 is devoted to the description of the 
species of wood-boring Beetles forming the tribe Terediles of 
Dumeril, the Anobiidae of most authors. Of these insects the 
authors enumerate and describe 87 species, or, excluding two 
species described by Fairmaire {Xyletinus sanguineocinctus and 
Pseudochina bubalus), of the distinctness of which they are 
doubtful, and another, Xylet. pallens (Germ.), of the occurrence 
of which in France they are not sure, 84 species as inhabitants 
of France. Of these, 10 are described as new; and the authors 
also describe four new generic groups. In its execution the 
work corresponds with the previous volumes of the series, and 
tlie descriptions are marked by the same minuteness of detail 
which is characteristic of MulsanPs writings. The plates con- 
tain a good series of outline illustrations of the structural 
characters of the insects.
