This group contains a number of species, which can be distin-

 Upper surface subimpunctate, polished. 



Sutural stria present in apical half more or less, either continuously or 

 as a series of punctures. 

 Mesosternal emargination broad and extremely feeble ; size small : front 



with an impressed puncture stygicilS Lee. 



Mesosternal emargination narrower, distinct; size larger ; front flat. 

 Narrowly oval ; pygidium fi__uely, sparsely punctate ; piosternal lobe 



narrowly and evenly rounded illteri'liptlis Beauv.

 Anterior tibise not arcuate, the apical tooth as prominent as the preceding. 

 Fiontal stria distinct, sometimes interrupted in the middle; outer thoracic 

 stria entire. 

 Piopygidium coarsely sparsely and more or less unevenly punctate, the 



interspaces smooth and impunctate ...lUerdai'illS Hoffm. 



Propygidium much more finely evenly and densely punctate, the punc- 

 tures intermingled with others which are minute but deep and dis- 

 tinct. 



Anterior tibije broad, coarsely and strongly 5-dentate plllto n. sp. 



Anterior tibiae narrower, much more finely and closely pluridentate ; 



species much smaller fractifi'OllS n. sp. 



P'lontal stria obsolete, represented only by feeble and unevenly discon- 

 nected traces toward the sides ; outer thoracic stria abbreviated behind 

 the middle IllomiOIl n. sp. 



The above species are all intensely black throughout, the legs 

 sometimes rufescent. 



H. Tirgiliiae. — Broadly oval, highly- polished, the minute punctules 

 extremely feeble and sparse. Head rather more distinctly punctulate, the 

 frontal stria not reentrant, narrowly and more or less completely interrupted 

 in the middle. Prothorax twice as wide as long, the sides strongly convergent,
