  and 
  the 
  other 
  distal, 
  laminate, 
  which 
  thins 
  out 
  at 
  its 
  apex 
  and 
  ends 
  in 
  a 
  small 
  tooth- 
  

   like 
  spike 
  ; 
  fourth 
  joint 
  twice 
  (or 
  a 
  little 
  less) 
  its 
  distal 
  width 
  ; 
  fifth 
  joint 
  about 
  as 
  

   long 
  as 
  the 
  fourth 
  and 
  as 
  long 
  as 
  broad 
  ; 
  sixth, 
  seventh, 
  and 
  eighth 
  equal, 
  but 
  

   increasing 
  slightly 
  in 
  width 
  ; 
  the 
  sixth 
  exactly 
  as 
  long 
  as 
  wide, 
  the 
  eighth 
  wider 
  than 
  

   long 
  ; 
  all 
  these 
  three 
  distinctly 
  larger 
  than 
  the 
  fifth 
  ; 
  the 
  ninth 
  and 
  the 
  tenth 
  just 
  

   transverse 
  and 
  as 
  wide 
  as 
  the 
  eighth 
  ; 
  the 
  eleventh 
  longer 
  than 
  broad 
  and 
  somewhat 
  

   spindle-shaped. 
  All 
  the 
  joints 
  from 
  the 
  fifth 
  to 
  the 
  tenth 
  have, 
  besides 
  various 
  rather 
  

   long 
  and 
  strong 
  bristles, 
  a 
  certain 
  number 
  of 
  large 
  and 
  long 
  sensoria, 
  which 
  are 
  almost 
  

   as 
  long 
  as 
  the 
  joints 
  themselves 
  and 
  project 
  rather 
  conspicuously 
  beyond 
  their 
  distal 
  

   extremities. 
  Mandibles 
  (fig. 
  2, 
  4) 
  bidentate, 
  with 
  the 
  apical 
  tooth 
  projecting 
  and 
  

   acute 
  ; 
  ventral 
  surface 
  with 
  about 
  a 
  dozen 
  ridges, 
  transversely 
  obliquely 
  arranged. 
  

   The 
  proximal 
  process 
  about 
  as 
  long 
  as 
  the 
  mandible, 
  with 
  eleven 
  transverse 
  raised 
  

   laminae 
  ; 
  the 
  first 
  (proximal) 
  has 
  a 
  tooth-like 
  appearance 
  ; 
  bristles 
  as 
  in 
  figure.
