  Metanotum 
  smooth, 
  side 
  areas 
  each 
  with 
  a 
  short 
  hair 
  ; 
  the 
  middle 
  area 
  slightly 
  

   swollen 
  and 
  (after 
  potash) 
  exhibiting 
  a 
  trace 
  of 
  reticulation 
  at 
  the 
  sides. 
  Propodaeum 
  

   more 
  than 
  twice 
  as 
  broad 
  as 
  long, 
  sides 
  nearly 
  parallel 
  ; 
  edge 
  between 
  pleura 
  and 
  ster- 
  

   num 
  defined, 
  smooth 
  and 
  very 
  flat 
  ; 
  central 
  keel 
  short 
  and 
  not 
  distinct. 
  Spiracle 
  

   oval, 
  as 
  far 
  from 
  the 
  centre 
  as 
  the 
  length 
  of 
  the 
  segment. 
  Below 
  the 
  spiracle 
  are 
  three 
  

   hairs 
  on 
  the 
  metapleurae. 
  Posterior 
  edge 
  of 
  the 
  propodaeum 
  considerably 
  excavated 
  

   in 
  the 
  middle 
  to 
  receive 
  the 
  abdomen. 
  

  

  Abdomen 
  sessile, 
  brown, 
  slightly 
  shining, 
  petiole 
  minute, 
  tergites 
  subequal 
  in 
  length, 
  

   medianly 
  smooth 
  and 
  faintly 
  reticulate 
  on 
  the 
  overlapping 
  sides 
  ; 
  spiracles 
  small, 
  

   nearly 
  circular. 
  Each 
  tergite 
  bears 
  a 
  posterior 
  row 
  of 
  short 
  hairs 
  (incomplete 
  near 
  

   the 
  sides 
  on 
  tergite 
  1) 
  ; 
  in 
  front 
  of 
  the 
  row 
  at 
  the 
  sides 
  are 
  one 
  or 
  two 
  irregular 
  short 
  

   hairs> 
  and 
  from 
  tergite 
  2 
  onwards 
  there 
  is 
  a 
  more 
  or 
  less 
  continuous 
  post-median 
  row 
  ; 
  

   on 
  each 
  side 
  of 
  the 
  mid 
  line 
  on 
  all 
  the 
  tergites 
  one 
  of 
  the 
  hairs 
  is 
  the 
  longest 
  in 
  its 
  row. 
  

  

  Legs 
  conspicuous 
  for 
  their 
  length, 
  the 
  difference 
  being 
  in 
  the 
  posterior 
  pairs 
  of 
  

   tibiae. 
  All 
  the 
  legs 
  and 
  the 
  posterior 
  coxae 
  pale 
  yellowish 
  ; 
  the 
  anterior 
  and 
  mid 
  

   coxae 
  dark, 
  and 
  the 
  anterior 
  femora 
  a 
  little 
  infuscated. 
  Anterior 
  coxae 
  large, 
  a 
  little 
  

   swollen. 
  In 
  both 
  fore 
  and 
  mid 
  legs 
  the 
  preapical 
  subventral 
  bristle 
  is 
  long 
  and 
  stronger 
  

   than 
  the 
  hairs 
  of 
  the 
  ventral 
  row. 
  The 
  tibiae 
  are 
  densely 
  clothed 
  with 
  hairs 
  or 
  

   short 
  bristles. 
  The 
  hind 
  and 
  mid 
  tibiae 
  are 
  to 
  the 
  corresponding 
  femora
