﻿A 
  NEW 
  HISPID 
  BEETLE.

  Larva 
  (fig. 
  2). 
  The 
  full-fed 
  larva 
  is 
  flattish, 
  creamy 
  white, 
  and 
  measures 
  about 
  

   five 
  millimeters 
  in 
  length 
  (dried 
  specimen 
  mounted 
  on 
  card). 
  The 
  abdomen 
  has 
  

   ten 
  segments, 
  including 
  the 
  last, 
  on 
  the 
  underside 
  of 
  which 
  the 
  anus 
  is 
  situated 
  ; 
  

   the 
  thorax 
  is 
  three-segmented, 
  so 
  that 
  with 
  the 
  head 
  the 
  larva 
  is 
  composed 
  of 
  14 
  

   segments. 
  There 
  are 
  altogether 
  nine 
  pairs 
  of 
  spiracles 
  : 
  one 
  pair 
  on 
  the 
  mesothorax, 
  

   and 
  a 
  pair 
  on 
  each 
  of 
  the 
  first 
  eight 
  abdominal 
  segments, 
  each 
  spiracle 
  being 
  placed 
  

   on 
  the 
  side 
  of 
  the 
  dorsal 
  surface, 
  except 
  that 
  on 
  the 
  mesothorax, 
  which 
  is 
  ventral. 
  

   The 
  prothoracic 
  segment 
  is 
  considerably 
  expanded 
  laterally, 
  the 
  expansions 
  bein^ 
  

   rounded, 
  and 
  is 
  deeply 
  emarginate 
  in 
  the 
  middle 
  for 
  the 
  reception 
  of 
  the 
  head.

  meso-and 
  metathorax 
  are 
  not 
  expanded 
  laterally. 
  Each 
  abdominal 
  segment 
  has 
  

   a 
  slight 
  rounded 
  expansion 
  on 
  each 
  side 
  bearing 
  two 
  fine 
  hairs 
  at 
  the 
  edge 
  in 
  the 
  

   middle, 
  which 
  are 
  homologous 
  with 
  the 
  well 
  developed 
  projections 
  from 
  the 
  sides 
  

   of 
  the 
  segments 
  of 
  other 
  Hispid 
  larvae. 
  The 
  larva 
  has 
  no 
  legs. 
  

  

  Morphology 
  of 
  the 
  Larval 
  Mouth. 
  

   The 
  head 
  is 
  supported 
  in 
  the 
  prothorax 
  by 
  means 
  of 
  two 
  large 
  elongate-oval 
  

   structures 
  with 
  strongly 
  chitinised 
  edges 
  and 
  chitinised 
  supports 
  in 
  the 
  middle, 
  which 
  

   are 
  inclined 
  to 
  each 
  other 
  at 
  an 
  angle, 
  meeting 
  anteriorly 
  at 
  the 
  mandibles, 
  and 
  

   having 
  nearly 
  half 
  their 
  length 
  inside 
  the 
  prothorax. 
  Compared 
  with 
  the 
  size 
  of 
  

   these 
  structures, 
  the 
  mandibles, 
  which 
  form 
  their 
  apical 
  part, 
  are 
  minute.
