MEMOIR OF LATREILLPl 
As the names of Swammerdam, Linneeus, and Fa- 
bricius, have been respectively used to indicate 
particular epochs in the earlier stages of Entomo- 
logy, so may that of Latreille be employed to sig- 
nalize the most flourishing period of the science in 
more recent times. Almost from the date of his 
first publication till his death, his superiority in 
this department of Natural History seems to have 
been admitted by the general consent of all compe- 
tent judges ; every student was accustomed to look 
to him as a guide and instructor; and the most 
skilful, as well as the most inexperienced, have 
every where united in doing him homage as the 
*' facile princeps entomologorum." 
It is much to be regretted that no detailed bio- 
graphy of an individual so celebrated for his attain- 
ments in the branch of study to which he devoted 
himself, has yet been laid before the public. M. 
Audouin, an eminent student in the same depart- 
ment of science, has promised a historical notice
