  The 
  head 
  and 
  thorax 
  do 
  not 
  differ 
  from 
  the 
  same 
  parts 
  

   in 
  D. 
  septentrionalis, 
  the 
  mandibles 
  having 
  a 
  smooth 
  

   longitudinal 
  groove, 
  the 
  epistome 
  4-dentate, 
  with 
  the 
  

   two 
  median 
  teeth 
  very 
  small 
  and 
  approximated, 
  and 
  the 
  

   thorax 
  sinuate-angustate 
  towards 
  the 
  base, 
  dentate 
  at 
  

   the 
  angle, 
  and 
  minutely 
  granulate 
  in 
  the 
  basal 
  de- 
  

   pression 
  ; 
  but 
  the 
  elytra 
  differ 
  greatly 
  in 
  their 
  sharply- 
  

   grooved 
  strige, 
  broader 
  and 
  deeper 
  towards 
  the 
  sides, 
  

   with 
  corresponding 
  convex 
  interstices, 
  stride 
  continuing 
  

   well-marked 
  to 
  the 
  apex, 
  and 
  in 
  the 
  granulated 
  sides 
  and 
  

   apex. 
  The 
  transversely 
  grooved 
  ventral 
  segments 
  bring 
  

   the 
  species 
  within 
  the 
  definition 
  of 
  Dintichtis, 
  but 
  the 
  

   maxillse 
  are 
  not 
  much 
  more 
  obtuse 
  than 
  in 
  Scarites 
  suh- 
  

   terraneiis, 
  the 
  hooked 
  apex 
  being 
  less 
  prolonged 
  and 
  

   acute. 
  The 
  middle 
  tibiae 
  have 
  only 
  one 
  very 
  distinct 
  

   subapical 
  spine, 
  

  

  ScJdzogenius 
  multisetosus.

  The 
  chief 
  difference 
  between 
  this 
  species 
  and 
  S. 
  

   Truquii 
  lies 
  in 
  the 
  short 
  discoidal 
  stria 
  of 
  the 
  thorax, 
  

   which 
  in 
  S. 
  Truquii 
  reaches 
  nearly 
  to 
  the 
  fore 
  margin. 
  

   But 
  to 
  this 
  are 
  added 
  many 
  peculiarities, 
  e.g., 
  the 
  trans- 
  

   verse 
  anterior 
  groove 
  of 
  the 
  thorax 
  is 
  smooth 
  (not 
  punc- 
  

   tured 
  as 
  in 
  S. 
  Truquii) 
  ; 
  the 
  frontal 
  carinaB 
  are 
  not 
  all 
  

   straight, 
  nor 
  do 
  they 
  terminate 
  before 
  reaching 
  the 
  level 
  

   of 
  the 
  hind 
  border 
  of 
  the 
  eyes, 
  nor 
  do 
  the 
  middle 
  pair 
  

   join 
  behind 
  in 
  a 
  curved 
  carina. 
  The 
  7th 
  elytral 
  stria 
  is
