860 Recent Literature. [ August, 
our entomological readers. Beginning with the transformations 
and anatomy of a single genus, the author in the second part 
extended his studies to the anatomy of other Diptera, until the 
work promises, from what has already appeared, to be a worthy 
successor of those of Straus-Diirckheim, Lyonnet, Newport and 
Weismann. 
Part first appeared in 1875, and received the grand prize of the 
physical sciences given by the French Academy of Sciences. It 
treats of the habits, tegumentary system and its development, 
and the muscular system and its development of Volucella. 
Only the atlas of the second part has as yet been published; it 
comprises Plates x11-xxvi. The more notable figures are those 
illustrating the nervous system of various Diptera, the longitu- 
inal sections of the adult Volucella, with three enlarged views, 
representing in one the heart, etc., in another the trachee and 
air-sacs, and in a third figure the digestive and nervous systems. 
The enlarged longitudinal section of the head and proboscis of 
Volucella is especially valuable and noteworthy. There are also 
numerous figures of microscopical sections. The plates have 
been mostly engraved on steel by Lebrun
