occasion, being- elaborately adorned with models and carvings of 

 animals in shellwork, with which material the walls and roof were 

 most beautifully ornamented. 



The business of the Zoological Section, of which Dr. Froriep was 

 the chairman, and Dr. Goldfuss secretary, was opened by a commu- 

 nication from the President of the Entomological Society of France, 

 presented by M. Audouin, relative to the views of that Society. 



A memoir was read by Dr. Hammerschmidt of Vienna, relative to 

 Spermatozoa observed in insects. 



Dr. Berendt, of Dantzig, communicated some observations upon 

 insects found in amber, accompanied by figures of a species of Cer- 

 matia found therein : this memoir led to a considerable discussion, 

 in which the president and secretary, and Messrs. Audouin, Van 

 Heyden, and others, took part. 



Mr. Westwood presented his address upon the recent progress and 

 present state of Entomology, and exhibited a small and interesting 

 collection of exotic insects. 



At this and subsequent meetings of this section, M. Audouin made 

 the following communications and exhibitions : 



Observations upon the genus Serolis of Fabricius, of which 

 M. Audouin has ascertained the existence of two distinct species, 

 from the sea near Chili ; they differ considerably from each other, as 

 appeared by the illustrations of the species exhibited by M. Audouin, 

 as well as from the genus Brongniartia of Eights, established upon a 

 Patagonian species, which also belongs to the same group, and which 

 is especially interesting as being apparently analogous to the extinct 

 tribe of Trilobites. 



Memoir upon an East Indian species of ants, Formica Smaragdina, 

 the sexes of which are very different in their colours, the male being 

 brown : the nest is very interesting, being foimed of a very thin silk- 

 like tissue, which is found to be doubled. 



He exhibited a beautiful cocoon of some unknown Lepidopterous 

 insect from China, which is composed of wide open network, very 

 regularly arranged, with square spaces, leaving the interior visible, 

 and somewhat similar to the cocoons of some of the Hyperce. Also a 



leaf of a shrub from Madagascar {Eugenia ?) having a series of 



large oval eggs placed obliquely side by side along one edge of the 

 leaf, between the epidermis and the body of the leaf. Also the 

 singular crustaceous genus Prosopistoma of Lalreille, from Madagas- 

 car, which exactly resembles a Gyrinus. Also specimens of minute 

 larvae resembling those obtained from the eggs of Meloe, hatched from 

 eggs deposited by Sitaris hvmeralis. Also a small collection of sin- 

 gular exotic insects, from the collection at the Jardin des Plantes, in-
