This species differs from II. nubilus in respect chiefly ot 

 characters that do not lend themselves very readily to a tabu- 

 lar statement. It is notably larger and not nearly so dark in 

 colour, and its dorsal surface is distinctly more coarsely punc- 

 tulate. It can be readily separated, however, by the very 

 different sculpture of its labrum (mentioned in the tabulated 

 statement above) .

I have seen numerous specimens of this insect, and find 

 the colour of the dorsal surface black in all of them. Tho&e
