HEMARIS  TITYUS.  531

Larva*. — First   instar   (newly-hatched):    The    newly-hatched
larva  is   covered   with   small   black   tubercles  bearing  forked  black
hairs;  the  caudal  horn  placed  far  forward   on   the   8th   abdominal
segment,   and    rather    resembling    a    bristle    surmounted   with   two
black  hairs   (Jeffery) ;    the   hairs  on  the  head   and   scutellum  long,
stiff,  and  dark  in  colour,  their  bifid  character  being  merely  suggested
by  a  notch   at   the   tip ;   on   the   other   hand,  the   body   hairs   are
similar  to  those  of  the  newly-hatched  larva  of  H.  fuctformis^  only
black   instead   of  pale-coloured ;   the  caudal  horn   is   covered   with
minute    bristles,   but    no    basal    mammillae    are    apparent    (Bacot).
