Particles of wax secretions are found in varying amounts on the ventral surface, sometimes in such abun- dance as to make microscopic examinations difficult. Second larval instar.—Length, mm.; width mm. Except in point of size no differences have been discov- ered between this and the correspond- ing instar of A. citri. Third, larval instar (tig. 16).—Length, ; width, mm. Ex- cejjt in size no differ- ences have been dis- covered between this and the correspond- ing instar of .1.
