Fig. 44 Abdomen of female third nymphal instar, ventral view of caudal 
portion, showing gonapophyses of eighth (gv. 8) and ninth (gn. 9) segments, and 
pigmentation characteristic of sternum of eighth somite (s. 8). X 26.2. 
Fig. 45 Abdomen of female fourth nymphal instar, ventral view of caudal 
portion. All three pairs of gonapophyses represented: one pair of the eighth 
(gn. 8), and two pairs on the ninth segment (gn. 9, and gn. 9’). The adult ap- 
pendages which these form are shown with similar designations in figures 28 and.

Fig. 46 Abdomen of female fifth nymphal instar, ventral view of entire ab- 
domen, showing growth caudad of gn. 8, which now cover and extend beyond 
gn. 9. gn. 9’ now partly overlap the two median pairs of gonapophyses. X 9.7. 
Fig. 47 Abdomen of parasitized female fifth nymphal instar, from which
