METHODS. 
The collecting of large numbers of insects which were 
brought alive from the field to the laboratory was greatly 
facilitated by the use of a net which Professor Woodworth 
invented some time ago. The advantage of this net is that 
insects may be procured by sweeping, even in damp weather, 
without the injuries which are usually the result of such col- 
lecting. The making of this net has been previously des- 
cribed by Mr. E. T. Cresson, Jr., who uses it continually for 
collecting small flies along the sand. Since, however, the net 
is not as widely known as its advantages deserve, another 
description will be in place:— 
A strong piece of iron wire, three feet, eight inches long, is 
bent into a circle with a one foot diameter—the ends are then 
bent at right angles so as to lie adjacent and parallel to each 
other. These ends are inserted into the small end of a six 
inch ferrule and soldered fast. A short two foot handle will 
be found best for sweeping. The net consists of white muslin— 
a conical bag about eighteen inches deep. The tip is cut off 
where the circumference of the bag measures about three 
inches and is replaced by a small cloth bag four by six and a 
half inches. This small bag is sewed to the point at which the 
circumference of the large net is- four inches, thus leaving a 
sleeve which hangs down into the small bag—this small bag will 
just hold a quarter pound paper bag. ‘The sleeve of the large 
net ‘fits into the paper bag. When filled from a minute’s 
sweeping, the paper bag is pinched at the opening, taken out 
of the net and placed in a botanical can. Upon the return to 
the laboratory, the bag is opened at a well lighted window and 
the contents picked over for specimens. 
When insects of one species were found in sufficient number 
to make it desirable to keep a number of them under observa- 
tion as a unit, sets of capsules were bound together in tens as 
devised by Prof. Woodworth for his insecticide experiments. 
A piece of small iron wire two and a half inches long, sharpened 
at one end is thrust through the base of a gelatin quinine capsule 
so that the capsule is on the left of the wire with open end 
upward—a twist is made in the wire to hold the capsule on— 
then on the right side with open end in similar position, another
