Oblongo-ovata, depressa, nigra, nitida ; fronte bistriata ; pronoto 

 lateribus obsolete punctata, stria marginali antice anguste cana- 

 liculata ; elytris striis dorsalibus baud appendiculatis ; pygidio 

 fere laevi. 



L. 7 mill, (absque mandibulis). 



Oblong-oval, very flat, black and shining; the head smooth, 

 with two short bent frontal strife, labrum very small and 

 bilobed, $ mentum smooth and not carinate; the thorax 

 somewhat transverse, scarcely rounded off at the base, but 

 distinctly so at the anterior angles, lateral stria complete and 

 anteriorly narrowly canaliculate, within it there is an obscure 

 narrow line of punctures, base feebly bisinuous; the elytra, 

 striae, 1 dorsal short, basal, but well marked, 2 very short, 

 there is no apical appendage ; the propygidium has a few 

 lateral punctures, but they do not extend to the apex ; the 

 pygidium is seemingly smooth, but there is a fine and thinly 

 spread punctuation seen under the microscope ; the pro- 

 sternum, keel wide at both ends, but somewhat constricted in 

 the middle ; the anterior tibiae 4-dentate. 



The species may be placed near H. pygolissa, Mars., but 

 the thorax is not so much rounded off behind and the thoracic 

 lateral stria resembles that of Lioderma vicinum, Lee.
