identical in both species, and it is quite possible the specimen 

 before me really is a variety of B. venosus, Mg., bearing about 

 the same relation to it as B. obscitripennis does to B. marci ; the 

 only suggested differences in my species from B. venosus being 

 the grey instead of clear wings, and the pale yellow instead of 

 whitish colour of the abdominal pubescence.

This species has considerable resemblance to B. johannis $ , 

 but the distinctly yellowish thorax, with well-defined black dorsum, 

 at once distinguish it from the European species, in which the 

 whole thorax is black or blackish brown.
