angle  of  one  side  to  that  of  the  other;  the  posterior  border  straight 
between  these  same  angles.  The  second  tergite  with  its  keel  below 
the  level  of  the  margin  of  the  first  and  the  keel  of  the  third,  anteriorly 
and  posteriorly  produced.  The  keels  of  the  third  and  fourth  with  rounded 
anterior  and  acute  and  produced  posterior  angles.  The  keels  of  the 
rest  above  the  middle  of  the  sides,  horizontal,  complete,  with  rounded 
anterior  angle,  the  posterior  angle  acute  and  produced  beyond  the 
hinder  border  of  the  tergite.  The  dorsal  surface  smooth,  the  sulcus 
deep  and  complete,  running  from  keel  to  keel,  beginning  on  the 
fourth ,  but  not  so  strong  on  this  somite  as  on  the  rest.  Each  somite , 
except  the  anterior,  marked  with  a  fainter  longitudinal  sulcus.  The 
transverse  sulcus  and  the  anterior  furrow  finely  sculptured.  A  row  of 
piliferous  pores  along  the  posterior  border  and  also  a  similar  row  in  front 
of  the  transverse  sulcus.  Lateral  surface  exceedingly  finely  granular. 
Inferior  crest  absent.  Caudal  process  rather  slender,  but  normally 
formed.  Anal  sternite  normally  tuberculate.  Sternal  areas  normal,  not 
spined.  Legs  normal  with  claws  distinct. 
cf.  Slenderer  than  the  Q.  The  process  on  the  sternum  of  the  fifth 
somite,  thick,  long,  and  bifid.  The  copulatory  feet  of  normal  length, 
rather  wide  and  flattened,  terminating  in  two  processes,  the  external 
of  which  is  sublaminate,  more  or  less  contorted ,  with  a  spiniform  process 
on  the  distal  extremity  of  the  external  margin ,  constituting  on  sheath 
or  covering  for  the  internal  process,  which  is  flagelliform.

First  tergite  convex,  laterally  depressed  and  sub-carinate,  the  lateral 
portion  in  front  convex  and  evenly  continuous  with  the  lightly 
convex  anterior  border,  behind  also  convex,  but  depressed  or  sinuate 
at  the  base,  the  posterior  border  being  straight  and  not  sinuate.  The 
second  tergite  with  its  keel  large ,  horizontal ,  anteriorly  and  posteriorly 
produced ,  but  more  posteriorly  than  anteriorly  ;  third  and  fourth  with
