Professor Barnard raised larve living in running water. He con- 
fined them in a glass tube, one end closed by a porous substance, 
the other fastened to a faucet. In this way a steady flow of water 
of any desired strength can be kept up. Dr. Horn stated that, 
in 1874, when working with Dr. Le Conte on the Rhynchophora, 
among all their material only a single specimen of Aramiges fullen 
was contained, and that came from Montana. A year or two 
after, it was received from all parts of the country, and was 
dreaded as one cf the worst hot-house pests. How did this 
species spread so suddenly over so large a territory? Professor 
Lintner had first found the insect in 1876. Professor Dimmock 
found it very troublesome in hot-houses, especially on roses— 
The composition and properties of the light emitted by insects of 
the genus Pyrophorus forms the subject of a paper recently pre- 
sented to the Paris Academy of Sciences by MM. Aubert and 
R. Dubois. The spectrum of the light, examined by the spectro- 
scope, is very beautiful, but destitute of dark bands. When, 
however, the intensity diminishes, the red and orange disappear,
