and gives generalizations and a classification made from this point of 
view. He states that in the Ilesperidce. a sort of hermaphroditism must 
exist, as he has taken eggs out of the body of a male in two or three 
species. He also gives notes on the relations between Ants and larvae of 
Lyccenidce. Many remarks are made as to synonymy, and several new 
species described.

Finding that at present no generalization is possible as to the produc- 
tion of light by living beings, the author presents this voluminous 
memoir as the first of a proposed series of researches on this subject. It 
is devoted specially to Pyrophorus noctilucus , examples having been 
obtained from the island of Guadeloupe. He gives an extensive biblio- 
graphy and historical resume , and then a chapter on the general charac- 
ters of the Elateridce , with special reference to Pyrophorus. He obtained 
eggs which he found to be luminous ; discusses at. great length (pp. 43-55) 
certain luminous larvae which have been previously (apparently in all 
cases erroneously) supposed to be those of Elateridce ; and (pp. 55-64) 
describes the larva of Pyrophorus noctilucus — it is luminous, and the 
larvae fight furiously, giving off light in a flashing manner while doing so. 
Chapter iii is devoted to the anatomy of the porfect insect : skeleton, 
digestive, circulatory, and respiratory apparatus, nervous system, and 
reproductive organs. Chapter iv is given to the anatomy and histology
