Ixxi 



the entomological proceedings at the Gesellschaft deutscher Natur- 

 forscher und Aertze, or meeting of German Naturalists, held at Bonn 

 from the 18th to the 26th of September, 1835. 



The proximity of Bonn to those portions of the Rhine scenery 

 which are renowned for their grandeur and beauty induced a large 

 concourse of naturalists and others to attend this meeting. Not 

 fewer than four hundred members of the Association dined together on 

 the first day of the meeting, and their numbers received daily addi- 

 tions. Of the celebrated men present, Berzelius, Carus, Treviranus, 

 Goldfuss, Brongniart, father and son, Audouin, Dumortier, Bons- 

 dorff, Soemmerring, the Prince Von Wied, Jussieu, were amongst the 

 most distinguished, whilst Buckland, Lyell, Greenough, and Horner, 

 were the most celebrated amongst the many English who were 

 present. 



The Natural History Museum of Bonn is, in proportion to the 

 size of the University, of very considerable extent, and is kept in 

 the Palace of PopplesdoriF, a fine quadrangular building with a centre 

 court, about a quarter of a mile from the town. The lower part of 

 the building is prepared for the reception of the Museum and the 

 upper part is devoted to the residences of the Professors ; and from 

 the windows of their apartments, looking over the Botanical Garden, 

 the eye glancing past the Castle of Godesberg rests upon the distant 

 Siebenberg, or Seven Mountains, of which the Drachenfels is the 

 most renowned. 



This museum being under the direction of the celebrated geologist 

 Dr. Goldfuss, it is not surprising that the geological portion of the 

 collection should be of the greatest value : the number of fossil re- 

 mains and the beauty of the specimens is particularly striking. 



In entomology the museum contains two collections, one of con- 

 siderable extent arranged in glass cases upon show tables, and ex- 

 posed to view (being guarded from the light only by sheets of paste- 

 board fitted to the glass), and the other, of smaller extent, being the 

 collection of Dr. Nees Von Esenbeck, which was purchased by the 

 University when that professor quitted Bonn. In this collection 

 therefore, which is accompanied by an elaborately drawn up ma- 

 nuscript catalogue, are contained the insects described in Dr. Esen- 

 beck's recently published work upon the minute families of Hymeno- 

 ptera. It also contains a new species oiDiopsis ; a figure and descrip- 

 tion of which have been given in an additional memoir upon this genus 

 since read before the Linnsean Society by Mr. Westwood. 



It was in some of the splendid apartments of this palace that the 

 Geological, Botanical, and Zoological Sections held their sittings. 

 The apartment of the Zoological Section was quite adapted for the
