ved.  The  first  tergite  overlapping  the  head ,  not  sulcate  ;  the  rest , 
except  the  anterior,  furnished  with  the  four  ordinary  sulci  and  in  ad- 
dition (at  least  in  the  hinder,  half  of  the  body)  with  a  longitudinal 
furrow  on  each  side  of  the  middle  line.  Sternites;  the  first  four 
marked  with  a  single  longitudinal  sulcus;  the  rest,  except  the  last, 
with  a  transverse  sulcus  in  addition  to  the  longitudinal  one. 
Anal  somite;  tergite  with  raised  and  thickened  lateral  margins ,  angu- 
late  posterior  margin  ;  sternite  broad,  with  very  convex  posterior  angles. 
Pleurae  normal,  their  hinder  third  smooth,  without  pores;  anterior 
half  somewhat  depressed  and  porous;  pores  both  large  and  small, 
apparently  under  20  in  number.  (Legs  absent.) 
Length  12  mm. 
Except  for  the  difference  in  colouring,  this  species  is  scarcely  di- 
stinguishable from  Cr.  hortensis  (Leach)  ;  it  appears  however  to  be  less 
hairy  and  to  have  a  differently  shaped  maxillary  coxal  plate ,  the  an- 
terior margin  being  apparently  straighter,  the  appendages  more  slender , 
and  the  claw  longer  and  more  curved.

Flores:  Maumerie.  Two  mutilated  specimens. 
Colour  testaceous,  head  and  maxillary  feet  ochraceous.  The  whole 
body  more  or  less  hirsute. 
Head  plate  long,  rather  longer  than  wide  ;  sub-quadrate,  approxima- 
tely of  the  same  width  throughout ,  posteriorly  covered  by  the  ante- 
rior part  of  the  first  tergite,  the  covered  part  marked  behind  with 
two  very  short  sulci.  Antennae  short,  thick,  composed  of  11  or  15 
segments  (?  mutilated). 
Maxillary  coxœ  about  as  wide  as  long  with  the  anterior  border 
furnished  with  two  more  or  less  rounded  unarmed  prosternai  plates; 
maxillary  feet  rather  short,  stout,  the  terminal  claw  exceedingly  short 
and  slender  the  two  claws  so  short  as  to  be  wholly  incapable  of  meet- 
ing in  the  middle  line. 
Basal  plate  invisible.  First  tergite  simple,  marked  neither  with 
transverse  nor  with  longitudinal  sulci  ;  the  tergites  immarginate,  from 
the  third  sulcate,  marked  with  the  four  sulci  characteristic  of  the
