 punctata, subrugulosa. Capul cornu lanceolate oblique ascendente subtus 

 brevicarinato ; frons obliqua plana. Oculi prominuli. Palpi graciles ; 

 articulus 4us 3o longior. Antennae graciles, Ionga3. Prothorax sellatus,

 roughly punctured, slightly rugulose. Head as broad as the prothorax, 

 armed between the eyes with a long lanceolate very acute obliquely 

 ascending horn, which has a deep short keel beneath ; front oblique, flat. 

 Eyes prominent. Palpi slender, truncated obliquely at the tips; fourth 

 joint of the maxillary longer than the second and than the third. Antennas 

 slender, very much longer than the body ; first joint long, very stout ; 

 second stout, about half the length of the first; third long, slender; the

This genus is nearly allied to the preceding one. The specimen 

 characterized has probably not attained its full development, and in that 

 case the description is incomplete.
