  Family 
  SPHINDID^. 
  

  

  Very 
  similar 
  to 
  the 
  "Cioldae" 
  in 
  appearance 
  and 
  live 
  in 
  fungi. 
  Our 
  

   only 
  species 
  is 
  

  

  SPHINDUS 
  Chev. 
  

  

  S. 
  americanus 
  Lee. 
  Ft. 
  Lee, 
  Snake 
  Hill 
  (Sf) 
  ; 
  Newark 
  (Bf 
  ) 
  ; 
  Anglesea 
  

   (W) 
  ; 
  probably 
  throughout 
  the 
  State; 
  local 
  and 
  not 
  common. 
  

  

  Family 
  LUCANID^. 
  

  

  These 
  are 
  the 
  "stag 
  beetles," 
  so 
  called 
  because 
  in 
  some 
  species 
  the 
  

   male 
  has 
  the 
  mandibles 
  very 
  large, 
  branched, 
  resembling 
  stag 
  antlers. 
  

   Our 
  common 
  species, 
  however, 
  are 
  better 
  known 
  as 
  "pinching 
  bugs," 
  the 
  

   mandibles 
  being 
  of 
  moderate 
  size 
  and 
  not 
  branched. 
  The 
  antennae 
  have 
  

   a 
  leaf-like 
  club 
  at 
  tip, 
  the 
  blades 
  of 
  which 
  cannot 
  be 
  closely 
  opposed 
  or 
  

   folded. 
  T-he 
  larv^ 
  are 
  white-grubs 
  and 
  live 
  in 
  decaying 
  wood. 
  

  

  LUCANUS

   L. 
  elaphus 
  Fabr.

  male 
  (W). 
  

  

  L.

  Thunb. 
  Throughout 
  the 
  State 
  \l, 
  VII, 
  sometimes 
  locally 
  com- 
  

   mon 
  at 
  electric 
  light; 
  but 
  usually 
  in 
  small 
  numbers 
  only. 
  

  

  DORCUS 
  MacL. 
  

   D. 
  parallelus 
  Say. 
  Throughout 
  the 
  State 
  VI, 
  VII, 
  in 
  white-rotten 
  wood; 
  

  

  locally 
  common. 
  

   D. 
  brevis 
  Say. 
  DaCosta 
  (Say); 
  Weymouth 
  (Dke). 
  The 
  rank 
  of 
  this 
  

   species 
  is 
  in 
  doubt, 
  and 
  the 
  general 
  belief 
  is 
  that 
  it 
  is 
  only 
  an 
  aber- 
  

   ration 
  of 
  the 
  above; 
  but 
  that 
  is 
  disputed, 
  and 
  the 
  species 
  is 
  left 
  here 
  

   as 
  good.
