 Black, antennae, tibiae, tarsi, head in front and spot on the forehead ochreous ; 

 thorax punctulate, in front narrowly, at the sides broadly, margined with 

 white, the lateral margin enclosing a black spot; elytra reddish ochreous, a

 thorax with the anterior border tridentate behind, the lateral border produced 

 at the posterior angle, and with a quadrate yellow spot in the middle of the 

 base, elytra alutaceous, rather obsoletely punctulate, with the apex acuminate 

 and produced, orange-yellow, and triangular sutural spot dilated behind the 

 scutellum, a spot on the callus joining the base, and a deeply curved sub-apical

Kansas, Hudson's Bay. (Lecoute, Ulke.) 



The meta-epimera are black, so that it is the representative of H.
