  wide 
  as 
  the 
  forewing 
  and 
  rounded 
  at 
  its 
  apex. 
  The

  is 
  

   weakly 
  reticulated 
  and

  Theocolax 
  formiciformis 
  appears 
  to 
  be 
  a 
  common 
  parasite 
  of 
  

   Anohium. 
  having 
  been 
  recorded 
  from 
  several 
  species 
  of 
  that 
  

   genus. 
  It 
  is 
  also 
  said 
  by 
  several 
  authors 
  to 
  attack 
  (Hylesinus) 
  

   Leperisinus 
  fraxini 
  (Panzer), 
  but 
  since 
  it 
  is 
  known 
  to 
  have 
  been 
  

   confused 
  in 
  some 
  instances 
  with 
  Cerocephala 
  corniyera 
  Westwood. 
  

   a 
  common 
  parasite 
  of 
  this 
  host, 
  it 
  seems 
  very 
  likely 
  that 
  all 
  of 
  

   the 
  records 
  of 
  Theocolax 
  formiciformifi 
  from 
  Leperisiuus 
  fraxini 
  

   actually 
  refer 
  to 
  Cerocephala 
  cornigea 
  as 
  was 
  suggested 
  by 
  

   Waterston 
  (Rep. 
  Grain

  No. 
  9. 
  p.

  The 
  species 
  is 
  known 
  to 
  occur 
  in 
  England, 
  Sweden. 
  Germany, 
  

   and 
  New 
  Zealand 
  and 
  may 
  be 
  much 
  more 
  widely 
  distributed. 
  It 
  

   is 
  not 
  known 
  to 
  occur 
  in 
  America.

  This 
  Philippine 
  species 
  differs 
  from 
  formiciformis 
  by 
  being 
  

   distinctly 
  smaller, 
  by 
  lacking 
  the 
  toothlike 
  protuberances 
  on 
  each 
  

   side 
  of 
  the 
  facial 
  depression, 
  and 
  by 
  the 
  pedicel 
  in 
  the 
  female 
  

   being 
  as 
  long 
  as 
  the 
  first 
  and 
  second 
  segments 
  of 
  the 
  funicle 
  com- 
  

   bined. 
  It 
  is 
  also 
  somewhat 
  paler 
  in 
  color. 
  All 
  known 
  specimens 
  

   of 
  the 
  species 
  are 
  fully 
  winged 
  and 
  have 
  a 
  conspicuous 
  tuft 
  of 
  

   bristles 
  at 
  the 
  .junction 
  of 
  the 
  marginal 
  and 
  submarginal 
  veins. 
  

   The 
  head 
  is 
  oblong 
  with 
  parallel 
  sides 
  and 
  with 
  the 
  antennae 
  

   inserted 
  distinctly 
  below 
  the 
  ventral 
  extremities 
  of 
  the 
  eyes. 
  

  

  There 
  are 
  eight 
  specimens 
  in 
  the 
  U. 
  S. 
  National 
  Museum, 
  

   inclusive 
  of 
  the 
  type 
  series, 
  all 
  taken 
  by 
  C. 
  F. 
  Baker 
  at 
  Los 
  Banos, 
  

   Philippine 
  Islands. 
  One 
  of 
  these 
  bears 
  a 
  label 
  "on 
  scolytid 
  No.
