  This 
  species 
  is 
  very 
  distinct 
  from 
  any 
  other 
  known 
  to 
  me, 
  and 
  reminds 
  

   one 
  strongly 
  of 
  Paroxya.

  COLLINUS 
  SERIES. 
  

  

  This 
  is 
  a 
  tolerably 
  homogeneous 
  group, 
  in 
  which 
  the 
  pvozona 
  of 
  the 
  

   male 
  is 
  quadrate 
  or 
  nearly 
  so, 
  varying 
  from 
  a 
  little 
  longitudinal 
  (in 
  one 
  

   species 
  distinctly 
  longitudinal) 
  to 
  a 
  little 
  transverse, 
  and 
  the 
  interspace 
  

   between 
  the 
  mesosternal 
  lobes 
  in 
  the 
  same 
  sex 
  ranges 
  from 
  a 
  little 
  

   longer 
  than 
  broad 
  to 
  twice 
  as 
  long 
  as 
  broad. 
  The 
  tegmina 
  are 
  always 
  

   fully 
  developed, 
  rarely 
  do 
  not 
  surpass 
  the 
  hind 
  femora, 
  and 
  are
