  EMPOASCA 
  ALBOLINEA, 
  new 
  species. 
  

  

  Color 
  yellowish, 
  more 
  or 
  less 
  tinged 
  with 
  green, 
  a 
  pale 
  line 
  along 
  the 
  

   claval 
  suture 
  of 
  the 
  elytra, 
  length 
  3.5 
  mm. 
  

  

  Face 
  yellowish, 
  shading 
  into 
  greenish 
  below, 
  a 
  median 
  white 
  line 
  

   extending 
  to 
  the 
  clypeus, 
  a 
  white 
  spot 
  at 
  the 
  upper 
  end 
  of 
  each 
  of 
  the 
  

   lorae 
  and 
  two 
  oblique 
  white 
  dashes 
  just 
  below 
  the 
  crest 
  of 
  the 
  front, 
  

   diverging 
  toward 
  the 
  antennae. 
  In 
  some 
  specimens 
  these 
  white 
  mark- 
  

   ings 
  are 
  jjartly 
  lacking. 
  The 
  length 
  of 
  the 
  face 
  equals 
  the 
  breadth; 
  

   the 
  clypeus 
  exceeds 
  the 
  genae 
  but 
  little 
  and 
  is 
  rounded 
  below. 
  Vertex 
  

   yellow, 
  in 
  some 
  specimens 
  distinctly 
  tinged 
  with 
  green, 
  with 
  a 
  narrow 
  

   median 
  and 
  two 
  oblique 
  pale 
  lines 
  or 
  dashes 
  plainly 
  showing 
  in 
  the 
  

   best-marked 
  specimens, 
  but 
  wanting 
  in 
  others; 
  but 
  very 
  little 
  ])roduced 
  

   in 
  front, 
  its 
  length 
  contained 
  in 
  the 
  length 
  of 
  the 
  pronotum 
  almost 
  

   exactly 
  twice, 
  and 
  in 
  the 
  width 
  of 
  the 
  head 
  nearly 
  four 
  times. 
  Prono- 
  

   tum 
  yellow 
  with 
  a 
  median 
  stripe 
  and 
  the 
  hind 
  margin 
  pale; 
  there 
  is 
  

   also 
  a 
  distinct 
  white 
  spot 
  on 
  the 
  middle 
  of 
  the 
  anterior 
  margin, 
  and 
  

   another 
  on 
  either 
  side 
  back 
  of 
  the 
  compound 
  eye. 
  These 
  last 
  spots 
  are 
  

   quite 
  small 
  in 
  some 
  si)ecimens, 
  but 
  they 
  are 
  i)resent 
  in 
  all; 
  the 
  width 
  

   is 
  hardly 
  equal 
  to 
  that 
  of 
  the 
  head, 
  and 
  is 
  considerably 
  less 
  than 
  twice 
  

   the 
  length. 
  Scutellum 
  yellow, 
  slightly 
  green 
  toward 
  the 
  apex, 
  and 
  in 
  

   some 
  speciniens 
  there 
  is 
  a 
  pale 
  stripe 
  through 
  the 
  middle. 
  Elytra 
  pale 
  

   yellow 
  to 
  the 
  tip 
  of 
  the 
  abdomen; 
  hyaline 
  beyond, 
  and 
  with 
  a 
  conspic- 
  

   uous 
  whitish 
  line 
  along 
  the 
  claval 
  suture. 
  Abdomen 
  yellowish 
  or 
  

   greenish 
  yellow 
  above 
  and 
  below, 
  the 
  last 
  ventral 
  segment 
  of 
  the
