Male. Form subovate. Colour ochreous-yellow, 

 with brown markings ; or otherwise brown, with yellow 

 markings. Point of the vertex with a brown tridental 

 mark, aud three toothed marks at its base. A triangular 

 band across also the pronotum. Scutellum dark brown, 

 with yellow variegations. Elytra short and obtuse, 

 with six or seven diagonal and nearly parallel brown 

 bands, which cause the yellow nervures to appear very 

 broad and marked. Legs ochreous ; hind tibiae dilated, 

 and streaked with a longitudinal brown line. Eyes 

 grey. A black spot on the disc of the frons, and two 

 small ones above. 



Female larger and more ovate. Head and thorax 

 much mottled and variegated with brown. Elytra 

 fulvous-yellow, with all the membrane between the 

 nervures dark brown. Genital valves nearly twice as 

 long as the navicular valve. 



Common on most damp soils. Widely spread all 

 over Europe. Poland, Sweden, and France. 



The males of this species have a considerable re- 

 semblance to A. histrionicus, but the females are unlike 

 that species in several particulars.
