punctated.  V entral  surface  ochreous  to  pale  brown ;  dark  brown 
posteriorly ;  area  of  crescentic  groove  below  anus,  paler.  Stigmata, 
pale  with  a  broad  median  dark  brown  band. 
Engorged  female.  Leaden  grey  with  paler  irregular  markings ; 
integument  without  spots. 
Male.  Rich  dark  brown,  shining  with  a  very  clearly  defined 
reticulated  or  net-like  pattern  produced  by  the  paler  ground  colour. 
To  the  unaided  eye  the  animals  appear  both  striped  and  spotted. 
Mouth  parts  and  legs,  dark  red-brown ;  articulations  of  legs  not 
quite  so  clearly  defined  as  in  the  female.  Scutum,  rich  dark 
castaneous,  paler  towards  the  margins,  especially  posteriorly.  The 
bronzy  silvery  reticulations  being  clearly  defined,  but  rather  thickly 
studded  with  black  spots  and  suffused  with  coppery  green  reflections  ; 
the  reticulations  of  the  remaining  portions  of  the  dorsum  enclosing 
well-defined  areas ;  each  of  the  festoons  with  a  pale  bronzy  silvery 
spot,  some  of  which  are  nearly  equal  to  the  length  of  the  festoon, 
others  small  and  scarcely  visible ;  these  merge  into  large  dark 
castaneous  areas,  giving  each  festoon  an  ocellated  appearance. 
Ventral  surface  pale  leaden  grey ;  margins,  pale  red-brown ;  the 
intestinal  tract  showing  through  the  cuticle  as  pale  greyish  and 
blackish  blotches. 
Habits.  Little  is  apparently  known  of  the  life-cycle  ;  but  Hunter 
and  Hooker,*  who  attempted  to  rear  this  species  on  dogs,  say  that 
the  larvae  matured  in  six  to  seven  days,  and  then  left  the  host ;  that 
the  incubation  period  of  the  eggs  varied  from  twenty-six  to  thirty-one 
days ;  and  that  the  larvae  which  hatched  from  these  eggs  in  ihe 
beginning  of  September  were  still  living'  on  ist  of  March  following. 
Hosts.  Found  upon  ‘  horsekind  ’  and  cattle,  and,  according  to 
Mr.  Harry  Jackson,  is  most  plentiful  ‘  between  the  months  of  June 
and  October.  They  attack  the  ears,  tails  and  manes  of  the  animals ; 
and  are  worse  than  the  ordinary  silver  tick,  as  very  often  they  cause 
sores  in  the  ears  and  tail.’  In  addition  to  the  inside  of  the  ear,  other 
natural  cavities  are  also  selected  ;  and  it  bites  man  almost  immediately 
after  gaining  access  to  the  skin,  inflicting  a  painful  wound,  resembling 
the  pain  produced  by  salt  when  rubbed  into  a  freshly-cut  wound,  as 
the  writer  can  testify  from  experience.
