which obscures them, and dis-colours the Amber. This is 
especially the case in some of the Prussian Amber, but has 
not been noticed in the Pomeranian, which is always bright 
and clear. Dr. Burmeister states, that with respect to the 
families, genera, and species of insects found in Amber, they 
present a conformity in the majority of instances, with 
existing forms and even an identity of species. No new forms 
have been observed, and existing genera are readily recog- 
nised, nor do they belong to our latitudes, though many forms 
perfectly agree in this respect. This may especially be 
affirmed of the smaller flies and gnats, but particularly in the 
cockroaches, many beetles, and the majority of the Hymenop- 
tera, the resemblance to exotic forms is still greater. Many 
different species occur as in the present day, but only those 
families are preserved in this fossil resin which are found in 
woods or on trees, and scarcely ever water beetles. In the 
order Coleoptera, among the Carabidz is a small Dromius, 
and Germar has described another, which he calls Lebina 
resinata. Of the Elateride is a genus very similar to Elater 
cylindricus, and many smaller species. |Deperditores, two 
species resembling Anobium, Atractocerus, and a Cantharis. 
Heteromera, a small Opatrum allied to sabulosum. Also 
a Mordella) The leg of a Capricorn beetle. The 
Chrysomelide are more numerous, viz: a small, purple 
shining Haltica, several Crioceris, and a few Gallerucide. 
The Bostrychode are very numerous, viz:—a species of 
Platypus, several Bostrychi and Opatra. The Curculionide 
too, are tolerably abundant, particularly species of the genera 
Phyllobius, Polydrusus, Thylacites, and some forms allied to 
exotic groups. The Hymenoptera are very abundant, and 
amongst them several Ichneumonide, a Sphex of the genus 
Pepsis, resembling the American, and particularly the African 
species. There is also a small Bee, which appears to belong
