with black. Segment 1 transversely oblong basal spot over one half 

 of the length ; 2 complete dorsal longitudinal band, dilated at 

 anterior end and still more near posterior end, this dilatation 

 immediately followed by a contraction and then by a narrow complete 

 posterior ring; 3-7 broad dorsal longitudinal band, not fully inter- 

 rupted by very narrow, dorsally incomplete basal rings, very slightly 

 enlarged near the posterior end of 3-6 (the band as a whole being too 

 broad to make these usual dilatations conspicuous) ; 8-9 entirely blue, 

 exceptionally a terminal dorsal black dot on 9 ; 10 broadly black on 

 dorsum. Appendages (Text-fig. 33) black, tips of superior yellowish. 

 Wings hyaline, slightly tinged with greyish in adults. Pterostigma 

 black, very narrowly bordered with whitish.

and dorsal view. 



Appendages, right side 



9 . Light ochreous, to olivaceous and greenish blue according to 

 maturity. Dark colour at occipital foramen lighter and more diffuse. 

 Postocular spots larger, lined posteriorly only by a narrow line of 

 blackish or altogether fused to light colour of occiput ; line on 

 occipital border rather broad. Ante-humeral stripes considerably 

 broader, their lateral margin approaching very closely the humeral 

 suture. Humeral black limited to a narrow line at the suture ; black 

 dots in dorsal end of first and second lateral sutures. Black lines on 

 legs much narrower, interrupted at third femora and tibiae. Abdomen 

 much stouter than in male, dorsal black band comparatively narrower, 

 otherwise much the same. Strong vulvar spine, vulva to end of 

 abdomen. Pterostigma larger than in male, rather light greyish 

 ochreous.
