  claws 
  long, 
  divergent. 
  Cotyloid 
  surface 
  of 
  the 
  posterior 
  tibiae 
  semi- 
  

   cavernous, 
  having 
  a 
  long 
  outer 
  and 
  a 
  short 
  inner 
  line

  As 
  pointod 
  out 
  by 
  Pierce 
  (1909, 
  p. 
  341) 
  and 
  Van 
  Dyke 
  (1934, 
  p. 
  

   175), 
  Casey 
  was 
  in 
  error 
  in 
  sayin<j; 
  that 
  the 
  ocuhir 
  lolx's 
  were 
  not 
  

   fimbriate. 
  This 
  genus 
  is 
  at 
  once 
  separated 
  from 
  the 
  others 
  of 
  the 
  

   group 
  by 
  the 
  deep, 
  narrow, 
  lateral 
  sulci 
  of 
  the 
  rostnmi, 
  turning 
  al)- 
  

   ruptly 
  outward 
  at 
  the 
  junction 
  of 
  the 
  head 
  and 
  rostrum, 
  and 
  nearly 
  

   attaining 
  the 
  upper 
  basal 
  edge 
  of 
  the 
  scrobe.

  Form 
  more 
  elongate 
  and 
  parallel 
  than 
  most 
  of 
  the 
  others 
  of 
  the 
  

   tribe. 
  Color 
  brown, 
  front 
  of 
  rostrum 
  and 
  three 
  vittae 
  on 
  pronotum 
  

   gray, 
  elytra 
  irregularly 
  mottled 
  with 
  darker 
  brown 
  and 
  irrorate 
  with 
  

   light 
  gray, 
  or 
  black 
  with 
  scattered 
  light 
  gray 
  and 
  darker 
  scales. 
  The 
  

   scales 
  of 
  the 
  head 
  and 
  pronotum 
  appear 
  tessellate, 
  those 
  of 
  the 
  re- 
  

   mainder 
  of 
  the 
  body 
  large 
  and 
  imbricated. 
  Rostrum 
  heavy, 
  some- 
  

   wliat 
  constricted 
  at 
  base 
  beneath, 
  not 
  greatly 
  arched 
  dorsally; 
  median 
  

   sulcus 
  narrow 
  and 
  deep, 
  from 
  about 
  the 
  middle 
  of 
  the 
  rostrum, 
  usually 
  

   terminating 
  abruptly 
  at 
  junction 
  of 
  head 
  and 
  rostrum 
  but 
  occasionally 
  

   carried 
  up 
  onto 
  the 
  front 
  for 
  a 
  short 
  distance; 
  lateral 
  sulci 
  deep, 
  

   narrow, 
  bent 
  outward 
  at 
  junction 
  of 
  head 
  and 
  rostrum 
  and 
  continuing 
  

   down 
  the 
  sides 
  of 
  the 
  rostrum 
  nearly 
  or 
  quite 
  to 
  the 
  eyes. 
  Rostrum 
  

   separated 
  from 
  the 
  front 
  by 
  a 
  vague 
  transverse 
  impression, 
  which 
  is 
  

   sometimes 
  nearly 
  lacking; 
  head 
  and 
  rostrum 
  distinctly 
  but 
  sparsely 
  

   and 
  rather 
  finely 
  punctate, 
  and 
  with 
  subrecumbent 
  white 
  or 
  tawny
