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, etc., 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.

Notes on Australian Pentatomidae (Rhynch.). 



By E. BERGROTH, Turtola, Finland. 

 Stelgidophora pallida V. Duz. 



This insect was described as doubtfully belonging to Dictyo-

 Eurynannus Bergr. It is allied to Eurynannns, but so distinct

 described by me in Proc. Zool. Soc. Lond., 1905, II, pp. 153- 

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