  Female 
  genitalia 
  (fig. 
  56, 
  a, 
  b, 
  c). 
  — 
  Genital 
  tube 
  tubular, 
  mem- 
  

   branous, 
  with 
  supporting 
  rods, 
  or 
  baculi. 
  These 
  consist 
  of 
  a 
  rod 
  at 
  

   each 
  side 
  ventrally 
  and 
  another 
  on 
  each 
  side 
  dorsally. 
  The 
  latter 
  

   two 
  are 
  interrupted, 
  the 
  apical 
  portion 
  of 
  each 
  broadening 
  out 
  as 
  a 
  

   chitinous 
  plate 
  on 
  each 
  side 
  near 
  the 
  apex 
  of 
  the 
  tube. 
  Coxites 
  large, 
  

   fleshy; 
  styli 
  large, 
  chitinous, 
  with 
  long 
  setae. 
  Eighth 
  sternite 
  acutely 
  

   angulate, 
  the 
  apex 
  truncate 
  or 
  narrowly 
  rounded, 
  and 
  hairy. 
  

  

  Male 
  genitalia 
  (fig. 
  56, 
  d). 
  — 
  Heavily 
  chitinized; 
  as 
  seen 
  in 
  profile 
  

   very 
  thick, 
  abruptly 
  curved 
  at 
  about 
  basal 
  two-fifths, 
  base 
  and 
  apex 
  

   nearly 
  straight. 
  As 
  viewed 
  from 
  above, 
  sides 
  nearly 
  parallel, 
  apex 
  

   very 
  broadly 
  and 
  evenly 
  rounded, 
  deeply 
  excavated 
  below 
  the 
  median 
  

   orifice.

  EUPAGODERES 
  DECIPIENS 
  (LeConte), 
  variety 
  DUNNIANUS 
  Casey 
  

  

  Eupagoderes 
  dunnianus 
  Casey, 
  1888, 
  p. 
  240. 
  

  

  This 
  name 
  seems 
  to 
  have 
  caused 
  considerable 
  confusion. 
  Casey's 
  

   description 
  of 
  the 
  species 
  states 
  that 
  it 
  is 
  white, 
  with 
  the 
  striae 
  

   extremely 
  fine, 
  finely 
  and 
  remotely 
  punctate. 
  The 
  description 
  fits 
  

   the 
  type 
  very 
  well, 
  but 
  some 
  specimens 
  included 
  in 
  the 
  Casey 
  collec- 
  

   tion 
  series 
  are 
  the 
  usual 
  brown 
  specimens 
  of 
  decipiens 
  with 
  the 
  striae 
  

   slightly 
  less 
  well 
  marked 
  than 
  usual. 
  I 
  have 
  found 
  no 
  characters 
  

   other 
  than 
  those 
  given 
  above 
  that 
  distinguish 
  dunnianus 
  from 
  deci- 
  

   piens. 
  The 
  genitalia 
  are 
  the 
  same. 
  Although 
  this 
  is 
  merely 
  an 
  

   extreme 
  form 
  of 
  decipiens, 
  I 
  believe 
  the 
  name 
  should 
  be 
  retained, 
  as 
  

   specimens 
  occasionally 
  come 
  to 
  hand 
  that 
  are 
  very 
  robust, 
  white, 
  

   and 
  with 
  subobsolete 
  striae, 
  and 
  these 
  are 
  otherwise 
  difficult 
  to 
  place.
