These insects make very unsatisfactory looking specimens at 
best. Some methods of preparation are much better than others. 
Collect them dry, pin with good black pins, hold the head thorax 
and elytra in position until dry, and dry quickly. All of the smaller 
species should be mounted on paper triangles. A little alcoholic 
sol. of carbolic acid or corrosive sublimate injected into the soft 
abdominal parts is good.
