Mentum incised for two-thirds of the length, outer part attenuate 

 obhquely towards the tip which is sharp ; basal joint of labial palpi 

 very broad, sub-ovoid but more inflated inwardly, second one hardly 

 more than one-half the length of the basal one, and only half its 

 width, arcuate inwardly, obliquely truncate outwardly at tip, third 

 joint very slender and rod-like, about 2 mm. long, and planted at 

 the base of the outer truncate part of the second ; maxillary palpi 

 long, slender, basal one longer than the second which has the 

 shape of a very elongate cone very slender at base, apical one longer 

 than the first, slender, straight outwardly and rounded inwardly, 

 maxillas long, robust, upper lobe moderately short, antennae nine- 

 jointed, club tri-foliate, first joint of club concave, glabrous and 

 shining, the other two opaque and briefly pubescent ; head large 

 but a little longer than broad ; eyes large, showing nearly as much 

 on the upper as on the lower side, and divided briefly in front by 

 the canthus of the genge, the latter are broadly lanceolate or a little 

 ampliate at base, and often dentate at apex ; clj^peus more or less 

 deeply bi-sinuate laterally, obtuse or emarginate, and sometimes 

 dentate in front ; prothorax broad, convex, retuse in front, more or 

 less deeply excavate laterally in the male ; elytra ample, convex, 

 sometimes nearly tectiform {H. gigas), suture raised, they have 

 on each side seven striae the outer one of which is edged by a very 

 distinct carina reaching from the shoulder to the rounding of the 

 apical part, and another fine one beginning at some distance from 

 the base and reaching the apex, this last carina is really the outer 

 margin which is quite obliterated in the anterior lateral part, while 

 the fold of the epipleura has been increased in proportion, and may 

 be taken in the anterior part as the margin proper; pygidium 

 triangular, rounded at apex, hardly convex ; metasternum narrowed 

 in the median part, deeply impressed at base, and having a not very
