  Body 
  suboblong 
  ; 
  head 
  longer 
  than 
  broad 
  between 
  eyes, 
  

   lateral 
  lobes 
  a 
  little 
  longer 
  than 
  the 
  central 
  lobe, 
  hut 
  not 
  

   meeting 
  beyond 
  it, 
  the 
  lateral 
  margins 
  distinctly 
  reflexed, 
  

   rounded 
  at 
  apices, 
  a 
  distinct 
  curved 
  spine 
  a 
  little 
  outwardly 
  

   directed 
  in 
  front 
  of 
  each 
  eye;

  apex 
  of 
  head 
  ; 
  pronotum 
  about 
  twice 
  as 
  broad 
  at

  as 
  

   long, 
  roundly 
  deflected 
  towards 
  head, 
  lateral 
  margins 
  roundly 
  

   oblique, 
  lateral 
  angles 
  subprominent, 
  very 
  distinctly 
  toothed, 
  

   between 
  them 
  a 
  transverse 
  impression, 
  and 
  a 
  central 
  longi- 
  

   tudinal 
  ridge 
  which 
  neither 
  reaches 
  the 
  anterior 
  nor 
  the 
  

   posterior 
  margin, 
  anterior 
  area 
  irregularly 
  sculptured 
  or 
  

   rugose; 
  scutellum 
  much 
  longer 
  than 
  broad, 
  apparently 
  

   reaching 
  the 
  abdominal 
  apex 
  (abdomen 
  mutilated 
  in 
  type), 
  

   strongly 
  sinuate 
  on 
  each 
  side 
  near 
  base, 
  apex

  trun- 
  

   cate,

  very 
  distinct

  are 
  strongly 
  ridged

  short 
  distance

  This 
  genus 
  is 
  founded 
  on, 
  and 
  intended 
  to 
  elucidate, 
  the 
  

   species 
  described 
  by 
  Walker 
  as 
  Podops 
  asper, 
  the 
  condition 
  

   of 
  the 
  type 
  specimens 
  I 
  considered 
  being 
  too 
  bad 
  for 
  exact 
  

   determination 
  when 
  I 
  referred 
  to 
  them 
  in 
  1899 
  (Ann. 
  & 
  Mag. 
  

   Nat. 
  Hist. 
  (7) 
  iv. 
  p. 
  48). 
  They 
  have 
  recently, 
  by 
  the 
  skilled 
  

   attention 
  of 
  Mr. 
  Ewd. 
  Waterhouse, 
  been 
  thoroughly 
  cleaned 
  

   and 
  reset, 
  and 
  the 
  accompanying 
  figure 
  has 
  been 
  made 
  by
