Asiatic provinces with numerous acquisitions, and it was deemed ad- 

 visable that the discoveries of both should appear together. The result 

 is the highly important addition to the number of known species men- 

 tioned above. Most of them have been referred to already existing 

 genera, but in four instances, M. Faldermann found it necessary to 

 establish new genera. These he has named Platynomerus, Microderes, 

 Tanyproctus, and Pachymerus. The former of these is nearly allied to 

 Pristonychus, the second to Platymetopodis of De Jean; the third 

 contains two lamellicorn insects, and its station is indicated between 

 Melolontha and Scarabaeus ; the fourth likewise belongs to the lamelli- 

 corn section, and has considerable affinity 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 

 malcodermata, a new species of Lampyris (L. orientalis pi. 6. fig 6, 7), 

 is introduced, so closely resembling our native glow-worm that it might 

 readily be taken for a variety. The eastern insect, however, is distin- 

 guishable 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, Onthopagus 12. 

 This paper does not advance beyond the section Heteromera, but the 

 remaining tribes have to appear in a subsequent faciculus. The plates, 

 it may be added, are in general well executed, but in no instance are 

 dissections given. Magnified representations of the oral organs when 

 new genera are proposed, as in this case, should be regarded as quite 



indispensable. II. — Description de quelques Coleopteres recueillis dans 



un voyage au Caucase et dans les provinces transcaucasiennes Russes en, 1 834 

 etl835. Par T. Victor. This paper is chiefly occupied with descriptions 

 of those minute and singularly formed insects composing the family 

 Pselaphidoe. Many new localities are cited for species previously 

 known, and a considerable number described and figured, which are 

 considered new. We are bkewise made acquainted with a few minute 

 Coleoptera belonging to other families, which do not appear to have 



been previously noticed by entomologists 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 history of various species 

 of this interesting tribe of plants. Some new kinds are noticed, and 

 useful observations advanced on the synonomy of those formerly des- 

 cribed. It is accompanied with lithographic plates, illustrating the 

 structure of the flowers and pappus.
