the middle legs. When removed from the case, they move 
about with quick, jerky movements, actually jumping, like a 
flea, at times. They feed on grass and various water plants. 
Length of a larva, probably nearly full-grown, 6 mm. 
Case: A small, slender cylinder of long bits of reed, straw, 
sticks, ete., placed lengthwise. Usually one straw about twice 
the length of the case is attached to it dorsally, or two very 
long ones, laterally. Occasionally, a part of the case is 
constructed of grains of sand and tiny bits of miscellaneous 
material. 
Eggs: not observed.

154, the head of Eurynannus is unique in the Pentatomidae in
