  Hah. 
  Villa 
  Lerdo, 
  in 
  Durango 
  (Hoge). 
  

  

  From 
  B. 
  coxendix 
  (Say), 
  a 
  species 
  belonging 
  to 
  the 
  

   same 
  subgroup 
  of 
  Bemhidium, 
  our 
  species 
  differs 
  in 
  the 
  

   conspicuously 
  longer 
  and 
  narrower 
  thorax. 
  In 
  colours 
  

   and 
  sculpture 
  there 
  is 
  little 
  difference.

  {Hoge). 
  

  

  A 
  remarkable 
  species, 
  in 
  its 
  style 
  of 
  coloration 
  unlike 
  

   any 
  other 
  known 
  of 
  the 
  genus. 
  The 
  elytra 
  have 
  no 
  

   trace 
  of 
  fovese. 
  

  

  Lachnophorus 
  cuprellus. 
  

   L. 
  subaurato 
  (Bates) 
  proxime 
  affinis 
  ; 
  differt

   etc. 
  Nigro-geneus,

  tboraceque 
  Isetius

  Caput

  Thorax 
  

   parvus 
  cordatus 
  mox

  valde 
  

   angustatus,

  Noria

  Sinaloa,

   (Hoge). 
  Three 
  examples. 
  

  

  Closely 
  allied 
  to 
  the 
  Guatemalan 
  L. 
  siibauratus, 
  but 
  

   certainly 
  distinct 
  ; 
  the 
  elytra 
  are 
  more 
  narrowly 
  oblong 
  

   and 
  less 
  convex, 
  the 
  thorax 
  much 
  more 
  narrowly 
  cor- 
  

   date 
  and 
  narrowed 
  more 
  gradually 
  behind, 
  the 
  straight 
  

   sides 
  for 
  a 
  short 
  distance 
  before 
  the 
  base 
  being 
  the 
  same 
  ; 
  

   the 
  surface 
  is 
  not 
  coarsely 
  confluent-punctate, 
  as 
  in
