are aspecies of Diptera of the genus Bibio or Cecidomya, several spe- 
cies of Tipularie, large Curculionites allied to the Otiorhynchus, larvee or 
nymphs of Libellule, Blatte, Ichneumonide, Formicide and Arach- 
nida. All these fossils belong to extinct species, but their genera, 
which still exist, do not occur in Europe. 
«‘ The diurnal lepidopterous insect belongs to one of those genera 
the species of which are not numerous, and are at present confined to 
the islands of the Indian Archipelago or the warmest countries of the 
Asiatic continent. According to M. Blum of Leyden, they hover 
around the palm-trees, on which perhaps they feed in the state of 
caterpillars. The individual which has been named sepulta, to recall 
its antediluvian origin, belongs to the genus Cy/lo, and is allied to 
the Rohria, Camnus, and other neighbouring species ; but it cannot 
be referred to any of those known at the present day. 
“‘ The outline and form of this insect are so well-preserved, that one 
might imagine it lithographed on a schist: only the right side is 
alone preserved, which is perfectly untouched, with a portion of the 
thorax and a slight impression of the abdomen. The upper wing is 
in great part hidden by the under one, and it is impossible to say 
whether it presents other delineations than an apical ocellus sur- 
mounted by a white point; the other, the whole surface of which is 
seen, is of a brownish gray colour, as in the allied species, with a 
white costal spot, a sinuated, median transverse band, of the same 
colour, followed by two black ocelli bordered in white, connected 
exteriorly with two white spots. The extremity of this same wing 
is rather paler, almost whitish, and divided, as in most of the living 
species, by two parallel brown marginal lines. The caudal appendix 
is rather longer than in the Rofria, but situated in the same manner. 
The preservation of the specimen admits of distinguishing the out- 
line, and probably the true colour of the butterfly as it was before 
its incrustation.” 
I am not sufficiently acquainted with the species of exotic frogs 
to be able to compare them with the Rana aquensis, but I can assert 
that it differs entirely from those which exist in Europe. 1 await a 
favourable opportunity to allow me to describe and publish the fossil 
insects which for the last ten years I have collected in the gypsiferous 
beds of Aix; the number of the species I possess at the present time 
amounts to more than sixty.— Bulletin de la Société Géologique de

‘“‘T was engaged in describing for the Cryptogamic flora of Chili 
a new genus allied to Weissia, and in consequence was desirous of 
ascertaining the form and structure of the spores in the species which 
I had before me. What was my surprise to find, instead of spores 
in every capsule which ] opened, a kind of gemmz analogous to those 
which occur in the cups of Marchantia! They have not indeed the
