!Maris fronte cornu erecto sat gracili subtiliter punctulato ’ 
instructa ; prothorace ut B. trituber culati. 
Femina ut D. trituhercvJati. 
Less robust in appearance tban most of its congeners, and not 
dilated behind the middle of the elytra ; apart from this difference 
of form, and the totally different shape of the frontal horn in the 
male, I do not see any good character to distinguish this species 
from D. trituhercvJatus. The female before me has two round 
fovese on either side of the prothorax some distance within the 
lateral margin — one near the front, the other behind the middle — 
but it is doubtful whether this can be relied on as a constant 
character. 
The mentum of the male is smoothly tuberculate on either side, 
the cavity between the tubercles very deep and narrow (almost as 
in D. major ) ; that of the female is veiy rugose and extremely 
deeply and widely convex almost from the apex. The superior 
lolje of the maxillie is strongly dentate.
