 succeeded by another smaller triangular one on the 

 elytron. Abdomen dark brown, with a tendency to 

 fulvous at the edges and tip of the tail. Whole insect, 

 except the abdomen, punctured with black, except on 

 the white parts of the elytra. Legs reddish. Elytra 

 pale fulvous, with broad irregular brown bars enclosing 

 pale spaces. Elytral nervures brown. Wings blackish 

 grey, with dark nervures. Under-side pale umber.

 these insects is not restricted to the alder tree. They 

 may be taken often on the long grasses underneath 

 these bushes.
