 Gteniopus sulp)hureus, L. — I have never taken this species in the Fen

 passes its early stages in the stems of this plant. When full-grown, 

 about the end of July or beginning of August, it bores a hole through 

 the stem, and comes out on to the plant. When the plant is shaken, 

 it immediately drops, and alights on the water with its legs expanded. 

 Great care should be taken in capturing, killing and mounting this 

 insect, as it is covered with a sulphur-yellow dust which is easily 

 rubbed off. This dust or powder, it has the power of renewing 

 during life, in common with other members of the family. It occurs 

 plentifully in one part of the Fen. Orchestes rusci, Herbst.— By
