In the appendix to the " Europaischen Heiniptera," p. 394, Fieber 

 describes an insect as a variety of Conostethus roseus, Fall., to which 

 the present bears a great resemblance in many respects, but its stature 

 (nearly one-third larger), rounder head, and different colour of the 

 elytra (the two former characters not referred to by Fieber) render it 

 very conspicuous when placed alongside C. roseus.
