to examine the botany ; but who devoted his leisure hours to what has been 
called its sister science. This person having been carried off by fever while 
prosecuting his researches, M. Faldermann was employed to render his ento- 
mological discoveries available to the public. While engaged in this undertak- 
ing, another collector, named Menetries, returned from the Asiatic provinces 
with numerous acquisitions, and it was deemed advisable that the discoveries of 
both should appear together. The result is the highly important addition to the 
number of known species mentioned above. Most of them have been referred 
to already existing genera, but in four instances, M. Faldermann found it neces- 
sary to establish new genera. These he has named Platynomerus, Microderes, 
Tanyproctus, and Pachymerus. The former of these is nearly allied to Pristo- 
nychus, the second to Platymetopodis of De Jean ; the third contains two la- 
in ellicorn insects, and its station is indicated between Melolontha and Scarabaeus ; 
the fourth likewise belongs to the lamellicorn section, and has considerable affi- 
nity to Amphicoma. Several of the species are of considerable size and brilliant 
colours. Such especially is the Carabus Humboldtii, which is equal in size to 
any of our native species, and has the elytra finely glossed with coppery-red. 
Thirteen new Cetonias are described and figured, and many of them partake of 
the lustre and rich colouring which distinguish that beautiful tribe. The 
brachelytrous species amount to 16. Among the malacodermata, a new spe- 
cies of Lampyris (L. orientalis pi. 6, fig. 6, 7), is introduced, so closely resem- 
bling our native glow-worm that it might readily be taken for a variety. The 
eastern insect, however, is distinguishable by being broader, by having the elytra 
darker and more dilated behind, while there are three distinct ridges along the 
surface of each. Cicindela has received an accession of five species ; Cychrus 
1, Carabus 12, Harpalus 11, Cantharis 11, Silpha 6, Onthophagus 12. This 
paper does not advance beyond the section Heteromera, but the remaining tribes 
have to appear in a subsequent fasciculus. The plates, it may be added, are in 
general well executed, but in no instance are dissections given. Magnified re- 
presentations of the oral organs when new genera are proposed, as in this case, 
should be regarded as quite indispensable. II. Description de quelques Co- 
leopteres recueillis dans un voyage au Caucase et dans les provinces transcauca- 
siennes Russes, en 1834 et 1835. Par T. VICTOR. This paper is chiefly occu- 
pied with descriptions of those minute and singularly formed insects composing 
the family Pselaphidce. Many new localities are cited for species previously 
known, and a considerable number described and figured, which are considered 
new. We are likewise made acquainted with a few minute coleoptera belonging 
to other families, which do not appear to have been previously noticed by ento- 
mologists III Lettre sur le genre Xeranthemum. Par F. E. L. FISCHER, et 
C. A. MEYER. The object of this paper is to elucidate the structure and his- 
tory of various species of this interesting tribe of plants. Some new kinds are 
noticed, and useful observations advanced on the synonomy of those formerly 
described. It is accompanied with two lithographic plates, illustrating the struc- 
ture of the flowers and pappus.
