  A 
  female 
  specimen 
  in 
  the 
  British 
  Museum 
  was 
  taken 
  at 
  

   Antongil 
  Bay, 
  and 
  Dr. 
  Sicard 
  has 
  found 
  both 
  sexes 
  at 
  

   Vohe"mar. 
  The 
  female 
  specimens 
  from 
  both 
  localities 
  are 
  

   completely 
  opaque 
  above, 
  but 
  the 
  single 
  male, 
  although 
  less 
  

   glossy 
  than 
  the 
  other 
  species 
  of 
  the 
  genus, 
  is 
  not 
  opaque. 
  

   Whether 
  the 
  difference 
  is 
  accidental 
  or 
  characteristic 
  we 
  

   must 
  await 
  further 
  observation 
  to 
  determine. 
  The 
  clypeus 
  

   is 
  rather 
  short, 
  very 
  little 
  attenuated 
  in 
  front, 
  feebly 
  im- 
  

   pressed, 
  but 
  not 
  toothed 
  at 
  its 
  apex. 
  The 
  pronotum 
  is 
  almost 
  

   devoid 
  of 
  punctures 
  at 
  the 
  lateral 
  margins, 
  except 
  the 
  front 
  

   angles, 
  and 
  at 
  the 
  middle 
  of 
  the 
  base. 
  The 
  punctures 
  of 
  the 
  

   elytra 
  are 
  not 
  very 
  large 
  and 
  not 
  arranged 
  in 
  distinct 
  rows,
