  Allied 
  to 
  A. 
  alternatus, 
  Dall., 
  by 
  the 
  apparently 
  shorter 
  

   and 
  distinctly 
  much 
  more 
  curved 
  posterior 
  tibiae, 
  different 
  

   colour 
  of 
  the 
  abdomen 
  above, 
  &c. 
  

  

  Some 
  difficulty 
  occurs 
  with 
  the 
  species 
  described 
  as 
  

   A. 
  planus, 
  Walk., 
  and 
  which, 
  as 
  I 
  pointed 
  out 
  in 
  1900 
  (Ann. 
  

   & 
  Mag. 
  Nat. 
  Hist. 
  (7) 
  vi. 
  p. 
  376), 
  is 
  a 
  synonym 
  of 
  A. 
  alter- 
  

   natus, 
  Dall. 
  This 
  applies 
  to 
  the 
  female, 
  which 
  he 
  first 
  

   described 
  ; 
  he 
  then 
  added 
  a 
  description 
  of 
  a 
  male 
  specimen, 
  

   which 
  is 
  another 
  species 
  altogether, 
  and 
  forms 
  the 
  type 
  of 
  

   the 
  above. 
  

  

  Tambourina, 
  gen. 
  nov. 
  

  

  Head 
  subquadrate, 
  about 
  as 
  long 
  as 
  breadth 
  between 
  eyes 
  ; 
  

   lobes 
  about 
  equal 
  in 
  length, 
  but 
  central 
  lobe 
  slightly 
  promi- 
  

   nent 
  and 
  a 
  little 
  apically 
  deflected 
  ; 
  ocelli 
  at 
  a 
  short 
  distance 
  

   from 
  base, 
  almost 
  as 
  near 
  each 
  other 
  as 
  to 
  eyes 
  ; 
  antennae 
  

   four-jointed, 
  first, 
  second, 
  and 
  fourth 
  joints 
  longest 
  and 
  

   about 
  subequal 
  in 
  length, 
  third 
  a 
  little 
  shortest 
  ; 
  pronotum 
  

   with 
  the 
  breadth 
  at 
  base 
  less 
  than 
  twice 
  its 
  length, 
  mode- 
  

   rately 
  deflected 
  on 
  anterior 
  area, 
  lateral 
  margins 
  sinuate, 
  

   lateral 
  angles 
  distinctly 
  roundly 
  prominent, 
  a 
  slightly 
  promi- 
  

   nent 
  subbasal 
  trausverse 
  ridge, 
  the 
  lateral 
  margins 
  at 
  anterior 
  

   area 
  obsoletely 
  crenulate 
  ; 
  scutellum 
  about 
  as 
  broad 
  at 
  base 
  

   as 
  long 
  ; 
  corium 
  subequal 
  in 
  length 
  to 
  head, 
  pronotum, 
  and 
  

   scutellum 
  together 
  ; 
  membrane 
  closely, 
  somewhat 
  reticu- 
  

   lately 
  veined 
  ; 
  rostrum 
  passing 
  the 
  anterior 
  coxae, 
  first 
  joint 
  

   not 
  reaching 
  base 
  of 
  head, 
  third 
  shortest 
  and 
  reaching 
  ante- 
  

   rior 
  coxae 
  ; 
  pro- 
  and 
  mesosterna 
  distinctly, 
  centrally, 
  longi- 
  

   tudinally 
  sulcate, 
  the 
  sulcation 
  of 
  the 
  latter 
  confined 
  to 
  its 
  

   anterior 
  area, 
  which 
  is 
  a 
  little 
  angularly 
  produced 
  between 
  

   the 
  anterior 
  coxae; 
  abdomen 
  beneath 
  in 
  male 
  with 
  a 
  distinct, 
  

   central, 
  broad 
  callosity 
  on 
  second 
  segment 
  ; 
  anterior 
  and 
  

   intermediate 
  femora 
  with 
  a 
  distinct 
  spine 
  beneath 
  near 
  apex, 
  

   posterior 
  femora 
  somewhat 
  strongly 
  incrassated, 
  spined 
  

   beneath 
  on 
  apical 
  third, 
  shortly 
  sparingly 
  tuberculate 
  near 
  

   upper 
  surface 
  ; 
  posterior 
  tibiae 
  distinctly 
  dilated 
  on 
  each 
  side, 
  

   roundly 
  above, 
  angularly 
  beneath, 
  the 
  dilatation 
  gradually 
  

   increasing 
  from 
  base 
  and 
  terminating 
  a 
  little 
  beyond 
  middle 
  ; 
  

   posterior 
  tarsi 
  three-jointed, 
  basal 
  joint 
  shortest. 
  

  

  Allied 
  to 
  Amorbus, 
  from 
  which 
  it 
  differs 
  by 
  the 
  relatively 
  

   shorter 
  and 
  broader 
  pronotum, 
  the 
  posterior 
  tibiae 
  dilated 
  on 
  

   each 
  side,
