  ex- 
  

   hibited 
  specimens 
  (3 
  c^c? 
  and 
  2 
  $9) 
  of 
  a 
  sawfly 
  hitherto 
  recorded 
  

   only 
  from 
  Germany 
  and 
  Holland, 
  Lygaeonematus 
  wesmaeli, 
  

   Tischb. 
  (= 
  solea 
  v. 
  Vollenh.), 
  and 
  stated 
  to 
  be 
  attached 
  in 
  both 
  

   countries 
  to 
  the 
  Larch 
  {Larix 
  decidua), 
  but 
  not 
  to 
  be 
  generally 
  

   common 
  in 
  either, 
  so 
  that 
  it 
  is 
  scarcely 
  reckoned 
  as 
  a 
  serious 
  

   pest 
  by 
  Continental 
  foresters. 
  

  

  The 
  larvae, 
  however, 
  from 
  which 
  these 
  specimens 
  were 
  bred 
  

   in 
  the 
  Pathological 
  Laboratory 
  at 
  Kew 
  Gardens 
  by 
  Mr. 
  Fryer, 
  

   F.E.S., 
  of 
  the 
  Board 
  of 
  Agriculture, 
  appeared 
  last 
  year 
  on 
  an 
  

   estate 
  in 
  Yorkshire 
  in 
  such 
  numbers 
  as 
  to 
  do 
  considerable 
  

   damage 
  to 
  a 
  fourteen-year-old 
  plantation 
  of 
  Larches. 
  They 
  

   were 
  supposed, 
  at 
  first, 
  to 
  belong 
  to 
  the 
  better 
  known 
  species 
  

   of 
  the 
  same 
  genus, 
  L. 
  lands, 
  Hartig 
  ; 
  but 
  the 
  imagines 
  reared 
  

   from 
  them 
  differ 
  from 
  those 
  of 
  lands 
  both 
  in 
  structure 
  and 
  

   colour, 
  the 
  vmderside 
  of 
  the 
  whole 
  body 
  being 
  entirely 
  pale, 
  

   whereas 
  in 
  laricis 
  it 
  is 
  practically 
  black 
  throughout. 
  (For 
  

   this 
  reason 
  v. 
  Vollenhoven 
  called 
  the 
  species 
  solea, 
  fancifully 
  

   comparing 
  its 
  style 
  of 
  coloration 
  with 
  that 
  of 
  the 
  fish 
  so 
  named.) 
  

   ti 
  this 
  respect, 
  and 
  also 
  in 
  the 
  form 
  of 
  the 
  ? 
  saw-sheath, 
  

   L. 
  wesmaeli 
  more 
  resembles 
  certain 
  of 
  its 
  congeners 
  which 
  

   feed 
  on 
  Pinus 
  (e. 
  g. 
  L. 
  saxeseni), 
  but 
  it 
  differs 
  from 
  these 
  in 
  

   several 
  points 
  of 
  structure, 
  the 
  saw 
  being 
  shorter 
  and 
  some- 
  

   what 
  less 
  abruptly 
  truncate, 
  and 
  the 
  abdomen 
  much 
  less 
  

   compressed 
  laterally 
  towards 
  its 
  apex. 
  Viewed 
  from 
  above 
  

   the 
  insect 
  has 
  so 
  much 
  the 
  appearance 
  of 
  laricis, 
  that 
  it 
  

   might 
  easily 
  be 
  mistaken 
  for 
  it, 
  and 
  it 
  is 
  quite 
  possible 
  that 
  

   collectors 
  may 
  find 
  the 
  two 
  forms 
  mixed 
  under 
  the 
  latter 
  

   name 
  in 
  their 
  collections. 
  

  

  Mr. 
  Fryer 
  has 
  kindly 
  given 
  a 
  pair 
  of 
  his 
  specimens 
  to 
  the 
  

   PROC.
