  of 
  the 
  lateral 
  cariiiae 
  of 
  the 
  proiiotnm 
  in 
  his 
  figure 
  as 
  arcuate 
  in 
  au 
  

   opposite 
  sense 
  to 
  that 
  here 
  described; 
  but 
  his 
  description 
  agrees 
  so 
  

   perfectly 
  with 
  the 
  other 
  characteristics 
  of 
  the 
  specimens 
  before 
  me 
  that 
  

   I 
  regard 
  this 
  as 
  an 
  accident. 
  Nevertheless, 
  I 
  append 
  hereto 
  the 
  descrip- 
  

   tion 
  furnished 
  by 
  him, 
  with 
  the 
  sketch 
  sent 
  me, 
  which 
  he 
  kindly 
  permits 
  

   me 
  to 
  publish 
  (see 
  Plate 
  IX,

  ijilose. 
  liead 
  moderately, 
  rarely 
  not 
  

   at 
  all, 
  prominent, 
  generally 
  but 
  little 
  if 
  any 
  longer 
  than

   unless 
  the 
  latter 
  (as 
  rarely) 
  is 
  distinctly 
  transverse; 
  face 
  almost 
  verti- 
  

   cal

  margin 
  subtruncate 
  or 
  feebly 
  

   convex, 
  separated 
  above 
  rather 
  or 
  very 
  narrowly, 
  at 
  most 
  but 
  little 
  

   farther 
  apart 
  than 
  the 
  width 
  of 
  the 
  equal 
  or 
  subequal 
  frontal 
  costa; 
  

   fastigium 
  more

  costa, 
  always 
  more 
  or 
  less 
  sulcate 
  or 
  with 
  elevated 
  lateral 
  

   margins,

  pos- 
  

   teriorly. 
  Pronotum 
  generally 
  subcompressed, 
  rarely 
  or 
  never 
  twice 
  as 
  

   long 
  as 
  the 
  average 
  breadth, 
  generally 
  only 
  half 
  as 
  long 
  again 
  as 
  the 
  

   average 
  breadth 
  even 
  in 
  the 
  male, 
  the 
  metazona 
  generally 
  more 
  or
