﻿REPORT 
  OF 
  THE 
  STATE 
  ENTOMOLOGIST 
  295 
  

  

  Both 
  at 
  Boston, 
  Mass., 
  and 
  at 
  Carson 
  City, 
  Ncv., 
  its 
  operations 
  have 
  

   been 
  very 
  injurious 
  to 
  the 
  vitality 
  of 
  the 
  infested 
  elms. 
  The 
  trees 
  in 
  

   Albany 
  and 
  Troy 
  have 
  suffered 
  severely 
  from 
  the 
  combined 
  attacks 
  of 
  

   the 
  elm-leaf 
  beetle 
  and 
  this 
  scale 
  insect. 
  The 
  many 
  trees 
  that 
  have 
  

   recently 
  died, 
  were 
  probably 
  killed 
  mainly 
  by 
  the 
  beetle, 
  but 
  many 
  are 
  

   now 
  suffering 
  severely 
  from 
  the 
  work 
  of 
  Gossyparia. 
  In 
  the 
  early 
  part 
  

   of 
  June 
  the 
  secretion 
  of 
  honey-dew 
  from 
  the 
  insects 
  on 
  a 
  badly 
  infested 
  

   tree 
  was 
  so 
  abundant 
  as 
  to 
  keep 
  the 
  walk 
  beneath 
  constantly 
  wet 
  and 
  in 
  

   almost 
  a 
  slimy 
  condition. 
  One 
  could 
  stand 
  under 
  the 
  trees 
  and 
  see 
  and 
  

   feel 
  the 
  continual 
  shower 
  of 
  the 
  tiny 
  drops. 
  The 
  injurious 
  nature 
  of 
  the 
  

   work 
  of 
  the 
  insect 
  was 
  more 
  plainly 
  evident 
  in 
  September, 
  when 
  its 
  

   presence 
  could 
  be 
  detected 
  at 
  a 
  glance 
  from 
  some 
  distance, 
  by 
  the 
  black- 
  

   ened 
  foliage 
  and 
  limbs 
  of 
  the 
  infested 
  trees 
  — 
  the 
  copious 
  secretion 
  of 
  

   the 
  coccids 
  on 
  the 
  leaf 
  and 
  branch 
  having 
  furnished 
  the 
  proper 
  medium 
  

   for 
  the 
  growth 
  of 
  the 
  blackening 
  fungus, 
  Coniothecium 
  saccharinum 
  Peck. 
  

   Thus 
  the 
  elm-leaf 
  beetle 
  and 
  Gossyparia 
  ^MorYvcig 
  on 
  the 
  same 
  trees, 
  trans- 
  

   formed 
  many 
  from 
  beautiful 
  ornaments 
  to 
  hideous 
  monuments 
  of 
  insect 
  

   devastation. 
  In 
  this 
  City 
  and 
  in 
  Troy, 
  Gossyparia 
  seems 
  to 
  prefer 
  the 
  

   English 
  and 
  Scotch 
  elms, 
  although 
  it 
  occurs 
  in 
  limited 
  numbers 
  on 
  the 
  

   American 
  elm. 
  In 
  both 
  of 
  these 
  cities 
  this 
  pest 
  is 
  so 
  generally 
  distrib- 
  

   uted 
  that 
  it 
  will 
  largely 
  aid 
  the 
  elm-leaf 
  beetle 
  in 
  the 
  destruction 
  

   of 
  our 
  European 
  elms, 
  unless 
  earnest 
  effort 
  be 
  speedily 
  made 
  for 
  the 
  

   preservation 
  of 
  our 
  favorite 
  shade 
  trees. 
  

  

  Description 
  of 
  the 
  Insect. 
  

  

  It 
  is 
  only 
  the 
  adult 
  females 
  that, 
  as 
  a 
  rule, 
  attract 
  the 
  attention 
  of 
  the 
  

   casual 
  observer. 
  They 
  may 
  be 
  seen 
  clustered 
  along 
  the 
  under 
  side 
  of 
  

   the 
  smaller 
  limbs 
  and 
  resembling, 
  in 
  a 
  general 
  way, 
  a 
  growth 
  of 
  lichens. 
  

   The 
  full-grown 
  viviparous 
  females 
  just 
  before 
  giving 
  birth 
  to 
  their 
  young, 
  

   are 
  about 
  o.i 
  inch 
  long, 
  oval 
  in 
  outline, 
  and 
  with 
  ends 
  shghdy 
  pointed. 
  

   They 
  are 
  surrounded 
  with 
  a 
  mass 
  of 
  a 
  white 
  Avoolly 
  secretion 
  which 
  also 
  

   partially 
  indicates 
  the 
  segmentation 
  along 
  their 
  margin 
  (PI. 
  XIV., 
  figs. 
  2, 
  

   5). 
  At 
  this 
  period 
  the 
  females 
  are 
  full 
  of 
  eggs 
  which 
  give 
  a 
  reddish 
  

   stain 
  when 
  crushed. 
  

  

  The 
  young 
  are 
  easily 
  recognized 
  on 
  the 
  infested 
  limbs 
  and 
  leaves 
  as 
  

   dark-eyed 
  yellow 
  specks, 
  being 
  less 
  than 
  0.5 
  mm. 
  or 
  /^ 
  of 
  an 
  inch 
  in 
  length. 
  

   They 
  are 
  of 
  an 
  elongated 
  oval 
  form, 
  rounded 
  anteriorly 
  and 
  tapering 
  

   posteriorly 
  to 
  a 
  pair 
  of 
  pointed 
  processes, 
  each 
  bearing 
  a 
  long 
  and 
  a 
  

   short 
  seta. 
  Each 
  segment 
  of 
  the 
  body 
  is 
  indicated 
  by 
  a 
  lateral 
  spine 
  ; 
  

   there 
  is 
  a 
  row 
  of 
  six 
  around 
  the 
  anterior 
  border 
  of 
  the 
  head, 
  and 
  a
