  tinctly 
  sinuate, 
  the 
  lateral 
  angles 
  a 
  little 
  prominent; 
  scu- 
  

   tellum

  The 
  structure 
  of 
  the 
  scutellum 
  is 
  the 
  most 
  distinguishing 
  

   character 
  of 
  this 
  Southern 
  Neotropical 
  genus 
  from 
  the 
  

   Palaearctic 
  genus 
  Jalla. 
  It 
  is 
  also 
  quite 
  distinct 
  from 
  the 
  

   Australian 
  genus 
  Jalloides, 
  in 
  which 
  Schouteden, 
  following 
  

   Stal, 
  but 
  with 
  doubt 
  and 
  hesitation, 
  placed 
  the 
  typical 
  species.

   The

  Head 
  about 
  as 
  long 
  or 
  only 
  slightly 
  longer 
  than 
  breadth 
  

   at 
  base, 
  the 
  lateral 
  lobes 
  distinctly 
  longer 
  than 
  the 
  central 
  

   lobe, 
  passing 
  but 
  not 
  meeting 
  beyond 
  it, 
  the 
  apex 
  being 
  thus 
  

   distinctly 
  cleft 
  ; 
  antennas 
  five-jointed, 
  first 
  joint 
  not 
  reaching 
  

   apex 
  of 
  head, 
  second 
  very 
  slightly 
  shorter 
  than 
  third, 
  fourth 
  

   and 
  fifth 
  longest, 
  subequal 
  in 
  length 
  ; 
  pronotum 
  more 
  than 
  

   twice 
  broader 
  between 
  the 
  lateral 
  angles 
  than 
  long, 
  the 
  

   lateral 
  angles 
  longly 
  broadly 
  produced, 
  the 
  lateral 
  margins 
  

   serrate, 
  finely 
  near 
  apex, 
  longly 
  towards 
  the 
  produced 
  angles, 
  

   anterior 
  margin 
  moderately 
  concave, 
  posterior 
  margin 
  trun- 
  

   cate 
  in 
  front 
  of 
  scutellum, 
  the 
  lateral 
  margins 
  before 
  the 
  

   produced 
  angles 
  almost 
  oblique 
  and 
  the 
  disk 
  from 
  the 
  same 
  

   area 
  sharply 
  obliquely 
  depressed 
  to 
  head 
  ; 
  scutellum 
  about 
  

   as 
  long 
  as 
  broad 
  at 
  base, 
  the 
  lateral 
  margins 
  moderately 
  

   oblique 
  for 
  about 
  half 
  their 
  length 
  from 
  base 
  and 
  then 
  more 
  

   longitudinally 
  narrowing 
  to 
  apex, 
  which 
  is 
  subangulate 
  ; 
  

   corium 
  slightly 
  longer 
  than 
  pronotum, 
  the 
  inner 
  apical 
  angle 
  

   rounded 
  ; 
  membrane 
  passing 
  the 
  abdominal 
  apex, 
  the 
  veins 
  

   mostly 
  longitudinal 
  ; 
  rostrum 
  reaching 
  the 
  posterior 
  coxae, 
  

   first 
  joint 
  reaching 
  base 
  of 
  head 
  ; 
  basal 
  abdominal 
  spine 
  

   reaching 
  the 
  anterior 
  margins 
  of 
  the 
  posterior 
  coxa? 
  ; 
  tarsal 
  

   joints 
  two 
  in 
  number. 
  

  

  Allied 
  to 
  Bcbmis, 
  Dall., 
  in 
  general 
  appearance 
  and 
  struc- 
  

   ture 
  of 
  head 
  and 
  lateral 
  pronotal 
  angles 
  ; 
  but 
  lateral 
  pronotal 
  

   margins 
  strongly 
  serrate, 
  ventral 
  spine 
  only 
  slightly 
  passing 
  

   posterior 
  coxae, 
  joints 
  of 
  antennas 
  different, 
  &c.
