XXXIX. Observations on the Fossil Insects of Aix in 
Provence, with Descriptions and Figures of Three 
Species. By the Rev. F. W. Hops, F.R.S., P.E.S. 
[Read 5th August, 1844.] 
In my late visit to the Continent, besides amassing a rich collection 
of recent insects, my attention was also directed to those which for 
some period or periods have been entombed in a fossil state. The 
major part were obtained at Aix in Provence, and at Sinigaglia in 
Italy. 
It is not my intention at present to describe any of the latter 
formation, and I only at present figure three from the former loca- 
lity, being doubtful if they will interest the Entomological Society 
equally as much as existing and recent species. 
Little I believe has been written on the fossil insects of Aix, 
excepting a memoir by Marcel de Serres* and Mr, Murchison, and 
some notices by Mr. J. Curtis, published in 1831 or 1832. Hein- 
rich Georg Bronn, in his ‘* Lethaa Geognostica,”’ (published in 
1838,) gives in his second volume a catalogue of the genera which 
have been discovered at Aix; and as it is a work little known to 
many of us, I insert the list of names there published, adding the 
letter B to designate those with which he was acquainted, and the 
letter H to particularize those which have fallen under my inspec- 
tion.
