Distribution.  The  only  examples  of  this  rather  handsome  species 
were  captured  by  Mr.  H.  Jackson  at  Waltham,  m  the  Mandeville 
district  of  Manchester,  on  the  i8th  January,  1909.  Several  examples 
of  both  sexes  were  forwarded  under  the  name  ‘  Pimento  Tick.’  No 
other  examples  were  seen,  though  carefully  searched  for  in  other 
districts.  This  is  the  first  recorded  occurrence  of  this  species  in 
Jamaica. 
Distribution  outside  the  Island  of  J amaica.  North  America, 
especially  near  the  Gulf  Coast ;  Neumann  also  gives  Mexico,  Peru, 
Brazil,  Paraguay,  Uruguay,  Chili  and  the  Argentine  Republic. 
BULL  FROG  TICK 
Amblyoinnia.  dissimile*  Koch. 
Engorged  or  replete  female.  Dull  ochreous  to  yellowish  grey; 
excretory  system  scarcely  showing  through  the  integument  in  pale 
yellow  but  irregular  lines.  Scutum,  chocolate-brown  with  dull  coppery 
markings,  forming  a  distinct  spot  at  the  apex.  Integument,  with 
numerous  well-defined  black  spots,  which  in  some  individuals  are 
surrounded  with  pale  brownish  yellow.  Length,  17  to  I7'50  mm. 
Greatest  width,  11-50  to  12  mm.  Height,  6-50  to  17-50  mm. 
Nymphs.  Scutum,  deeply  but  widely  punctate  with  two  sub¬ 
median  grooves  ;  dull  ochreous  yellow  ;  posterior  margin,  as  far  as  the 
eyes,  dark  brown ;  eyes,  red-brown.  Capitulum  and  legs  red-brown. 
Body,  leaden-grey  dorsally,  with  the  diverticula  showing  through  the 
cuticle  as  two  irregular  branching  lines,  slightly  diverging  from  the 
median  line  a  little  above  the  centre  ;  venter,  paler  at  the  margins 
(almost  white),  especially  in  front,  and  there  is  a  large  irregular  patch 
of  the  same  colour  surrounding  the  anal  orifice.  Ventrally  a  deep, 
narrow,  and  well-defined  groove  extends  from  the  anal  orifice  to  the 
margin,  and  there  are  also  two  broad  deep  divergent  grooves  on 
either  side  ;  dorsum,  with  a  broad  median  groove  terminating  near  the 
middle  of  the  back,;  and  there  are  two  irregular  depressions  on  both 
sides  of  this. 
Habits.  The  replete  or  fully  engorged  female  is  slightly  larger 
than  any  other  species  of  tick  found  in  the  Island,  the  length  of  this 
tick  being  equal  to  one-seventh  or  one-eighth  of  the  total  length  of 
its  host  (see  PI.  XIII,  fig.  3).  No  males  were  found,  though  very  careful
