are inserted far in front of the eyes, and in front of their insertion the head is 
narrowed so as to appear acuminate. In the male the basal joint of the antenne 
is not only elongate but is greatly incrassate, the second joint is short and thick, 
subtriangular, about as long as broad; in the female these two joints are more 
slender, though the basal one is still stout as well as elongate, the club is very 
slightly marked in the male, but is more distinct in the female. The anterior 
thoracic impression is very vague, the lateral ones, though smaller, are more 
definite. The elytra are nearly parallel-sided, are coarsely punctate, and have the 
humeral angles prominent, and a slight basal elevation on each side of the scutellum, 
and in the male there is in addition an obscure longitudinal elevation on the side 
of each elytron. 
In the male of this remarkable species the head is provided with true scrobes, 
visible from beneath as broad, deep depressions extending as far back as the 
under-surface of the eye. 
This was also found in Lanai, at an elevation of about 2000 feet, near a place called Koele, and was 
beaten from dead branches of trees.
