Structurally near the preceding (H. infirmus), but very 

 distinct from it by the sharp well-defined 3rd (uppermost) 

 external tooth of its front tibise, by the much finer and non- 

 rugulose puncturation of its frons, by its clypeus projecting 

 outward on either side distinctly beyond the contour of the 

 eyes, by its pronotum much less closely punctulate in the 

 lateral parts, by its elytra non-rugulose and less closely punc- 

 tured, by the basal joint of its hind tarsi much shorter in 

 proportion to the second joint, etc. The trilobed outline of 

 the head resembles that of infirmus, but with the middle lobe 

 less prominent and scarcely so wide.
