spend a large part of the time in water, they are obliged to come 
to the surface at intervals for a supply of fresh air. There are, 
however, a few Lepidopterous larve that are truly aquatic. One 
was described by Baron de Geer more than one hundred years ago.' 
This is the European Paraponyz stratiotalis. Another was described 
in 1884 by Wilh. Miiller-Blumenau.? This is a Brazilian insect, 
Cataclysta pyropalis, which, like the preceding, belongs to the 
family Pyralide. 
We have just received an account of a third species, which is 
described by J. Wood-Mason in a small pamphlet, entitled Report 
on the Paraponyx oryzalis, an Insect-pest of the Rice-Plant in 
Burma, This pamphlet was published in Calcutta in 1885. The 
insect described in it is supposed to be a congener of the European 
species referred to above, although only the larva and pupa have 
been described. The caterpillar is about seven millimetres in 
length and is abundantly supplied with tracheal gills. These are 
in the form of filaments, arranged in little bundles or tufts. There 
are four longitudinal rows of these tufts, extending nearly from one 
end of the body to the other; that is, two rows on each side of the 
ody —one above the spiracles, the other below them. 
: THE ORTHOPTERA oF New ENGLAND.—Professor Fernald has 
Just published a manual of the Orthoptera of New England, in 
which all the species found in that section are carefully described. 
Analytical keys are given for the determination of families, sub- 
families, and genera, and, wherever necessary, there are tables of 
Species. The work is an important addition to the series of hand- 
books prepared by this author. It will do much towards popular- 
izing a knowledge of this very important order of insects.
